Description
本発明は撮影装置及びその制御方法、移動型放射線撮影装置およびコンピュータプログラムに関し、特に、可搬性を有する電子カセッテとそれを組み合わされる移動型放射線発生装置とから構成される撮影装置に関するものである。
The present invention relates to an imaging apparatus, a control method therefor, a mobile radiation imaging apparatus, and a computer program, and more particularly, to an imaging apparatus including a portable electronic cassette and a mobile radiation generator combined therewith.
対象物に放射線を照射し、対象物を透過した放射線の強度分布を検出して放射線画像を得る装置が、工業用の非破壊検査や医療診断の場で広く一般に利用されている。このような撮影の一般的な手法としてはフィルム/スクリーン方式やCR方式が挙げられる。これらはいずれも感光性フィルムや潜像として画像を蓄積する蛍光体プレートを、非特許文献1により規格化されているカセッテといわれる収納ケースに入れて撮影に用いてきた。
An apparatus for irradiating a target with radiation and detecting a radiation intensity distribution that has passed through the target to obtain a radiographic image is widely used in industrial nondestructive inspection and medical diagnosis. As a general technique for such photographing, a film / screen system and a CR system can be cited. In any of these, a photosensitive film or a phosphor plate that accumulates an image as a latent image is put in a storage case called a cassette standardized by Non-Patent Document 1 and used for photographing.
一方、近年のデジタル技術の進歩により、放射線画像を電気信号に変換し、この電気信号を画像処理した後に、可視画像としてCRT等に再生することにより高画質の放射線画像を得る方式が普及している。図9はこのような放射線画像撮影装置を用いたシステムを示す概念図である。103は放射線検出センサ104を内蔵した放射線画像撮影装置である。放射線発生装置101によって発せられた放射線を被写体102に照射すると、被写体を透過した放射線は蛍光体を介して可視光に変換され、放射線検出センサ104の二次元の格子状に配列した光電変換素子によって電気信号として検出される。この放射線画像撮影装置103に対して読出し駆動や画像転送などの制御を行う制御部105が接続されており、放射線画像撮影装置103から出力された画像をデジタル画像処理し、モニタ106に被写体の放射線画像を表示する。
On the other hand, with the recent progress of digital technology, a method of obtaining a high-quality radiographic image by converting a radiographic image into an electric signal, processing the electric signal, and reproducing it as a visible image on a CRT or the like has become widespread. Yes. FIG. 9 is a conceptual diagram showing a system using such a radiographic imaging apparatus. Reference numeral 103 denotes a radiographic image capturing apparatus incorporating the radiation detection sensor 104. When the subject 102 is irradiated with radiation emitted by the radiation generation device 101, the radiation transmitted through the subject is converted into visible light through the phosphor, and the photoelectric detection elements arranged in a two-dimensional lattice pattern of the radiation detection sensor 104 are used. It is detected as an electrical signal. A control unit 105 that controls read-out driving, image transfer, and the like is connected to the radiation image capturing apparatus 103, performs digital image processing on an image output from the radiation image capturing apparatus 103, and displays radiation of the subject on the monitor 106. Display an image.
従来、この種の撮像装置は、放射線室に設置され利用されてきた。しかし、近年、より迅速かつ広範囲な部位の撮影を可能にするため、薄型で軽量な可搬型の撮影装置(電子カセッテという)が開発されている。その結果、放射線室内でのカセッテ撮影だけではなく、回診の分野にも適用される撮影システムが提案されている(特許文献1(第2-3頁、第1図))。
Conventionally, this type of imaging apparatus has been installed and used in a radiation room. However, in recent years, a thin and lightweight portable imaging apparatus (referred to as an electronic cassette) has been developed in order to enable imaging of a wide range of parts more quickly. As a result, there has been proposed an imaging system that can be applied not only to cassette imaging in a radiation room but also to the field of rounds (Patent Document 1 (page 2-3, FIG. 1)).
近年、電子カセッテに用いられる通信手段として無線通信の利用が進み、通信ケーブルがない状態でデータ通信をすることができる長所から広く使用されるようになってきている。しかし、従来の有線ケーブル方式に比べて、安定した通信を維持する信頼性は相対的に低く、また、放射する電磁波の医療機器、生体機器等への影響も大きくなるので、きちんとした管理をするのが望ましい。
In recent years, the use of wireless communication has progressed as a communication means used in electronic cassettes, and has come to be widely used due to the advantage that data communication can be performed without a communication cable. However, compared to the conventional wired cable system, the reliability to maintain stable communication is relatively low, and the influence of radiated electromagnetic waves on medical devices, biomedical devices, etc. is also increased, so manage properly Is desirable.
本発明は上述の課題に鑑みなされたものであり、撮像装置が無線制限区域に立ち入る場合に、適切に無線通信を制限するための技術を提供することを目的とする。
The present invention has been made in view of the above-described problems, and an object thereof is to provide a technique for appropriately restricting wireless communication when an imaging apparatus enters a wireless restricted area.

前記認識手段が無線制限区域への侵入を認識したことに応じて、前記無線通信機能を制限する制御手段と

さらに、本体21には無線制限を認識するための情報を受信する受信手段36が設けられている。外部に設けられた発信手段からの情報に基づき、無線制限を認識し、通信手段34、35による通信に制限をかける仕組みになっている。本実施形態では図3に示すように施設壁面に設けられたゲート40に無線制限区域切換えを報知するための発信手段41が設けられ、ゲートを通過した際に受信手段36で信号を受信することで無線制限区域の切換えを認識するものである。ここで、無線制限区域とは、医療機器や生体機器等に対する電磁波による影響を抑えるために、移動型撮影装置20が有する無線通信機能を制限すべき区域をいう。このような無線制限区域としては、例えば、病院や検査所等の医療施設における、電磁波の影響を受けうる測定・検査装置や医療機器が設置・使用される区域及びその周辺が挙げられる。例えば、図4に示すようなレイアウトの院内のフロアにおいて、図4において斜線(ハッチング)が施された区域A1は無線通信の影響を受けやすい機器を設置しているスペースであり、無線制限をすべき無線制限区域である。一方、入院患者の病室はA2、A3の区域にあり、ここでは回診撮影のために無線通信が必要になる。そこで、A2、A3の区域の入り口近傍にゲート40、42を配置し、制限区域切換え信号を発信している。このように、移動型撮影装置20は、外部の装置である発信手段41から無線制限区域の存在を示す信号を外部から受信したことに応じて、無線制限区域への侵入を認識する。これにより、この信号の受信に応じて無線通信の制限をすることができる。すなわち、移動型撮影装置20は、無線制限区域を特定する情報を取得し、当該情報に応じて無線通信機能を制限する。
Furthermore, the main body 21 is provided with receiving means 36 for receiving information for recognizing wireless restrictions. Based on the information from the transmitting means provided outside, the wireless restriction is recognized and the communication by the communication means 34 and 35 is restricted. In the present embodiment, as shown in FIG. 3, the gate 40 provided on the wall of the facility is provided with a transmission means 41 for notifying the switching of the restricted radio area, and the signal is received by the reception means 36 when passing through the gate. Recognizes switching of radio restricted areas. Here, the wireless restricted area refers to an area where the wireless communication function of the mobile imaging device 20 should be restricted in order to suppress the influence of electromagnetic waves on medical devices, biological devices, and the like. Examples of such a wireless restricted area include an area where a measurement / inspection apparatus and medical equipment that can be affected by electromagnetic waves are installed and used in a medical facility such as a hospital or a laboratory, and the vicinity thereof. For example, in the hospital floor having the layout as shown in FIG. 4, a hatched area A1 in FIG. 4 is a space in which devices that are easily affected by radio communication are installed, and radio restrictions are imposed. It is a radio restricted area. On the other hand, hospital rooms of hospitalized patients are in the areas of A2 and A3, and here, wireless communication is required for round trip imaging. Therefore, gates 40 and 42 are arranged in the vicinity of the entrances of the areas A2 and A3, and a restricted area switching signal is transmitted. As described above, the mobile imaging device 20 recognizes the intrusion into the wireless restricted area in response to receiving a signal indicating the presence of the wireless restricted area from the transmission unit 41 which is an external device. As a result, radio communication can be restricted in accordance with reception of this signal. That is, the mobile imaging device 20 acquires information specifying the wireless restricted area, and restricts the wireless communication function according to the information.
(処理手順)
以上のような移動型撮影装置20を使用した際のワークフローを図5A、図5Bのフローチャートを参照して説明する。以下、移動型撮影装置20が実行する処理は、制御部32の制御に基づいて実行される。 (Processing procedure)
A workflow when using themobile imaging device 20 as described above will be described with reference to the flowcharts of FIGS. 5A and 5B. Hereinafter, processing executed by the mobile imaging device 20 is executed based on the control of the control unit 32.
以上のような移動型撮影装置20を使用した際のワークフローを図5A、図5Bのフローチャートを参照して説明する。以下、移動型撮影装置20が実行する処理は、制御部32の制御に基づいて実行される。 (Processing procedure)
A workflow when using the
準備手続として、ユーザが移動型撮影装置20を稼働させるための不図示のACケーブルを商用電源に接続すると、移動型撮影装置20は、あらかじめ電力を本体バッテリ31に対して充電する(S100)。不図示の外部通信手段を介し病院内のRIS端末からのオーダー情報を移動型撮影装置20の制御部32にアップロードする(S101)。転送された情報は入出力部33にてリスト表示され(S102)、ユーザとしての技師は情報を確認する(S103)とともに、優先度や移動ルートを考慮し回診撮影の大まかなスケジュールを計画する(S104)。表示される内容は患者氏名、性別などの患者情報や病室番号、撮影部位や撮影姿勢等の撮影要件などである。そして、充電の完了に応じてACケーブルは取り外される(S105)。本体21に撮影部10が搭載されていない場合は、搭載される(S106)。
As a preparation procedure, when a user connects an AC cable (not shown) for operating the mobile imaging device 20 to a commercial power source, the mobile imaging device 20 charges the main battery 31 with power in advance (S100). Order information from the RIS terminal in the hospital is uploaded to the control unit 32 of the mobile imaging apparatus 20 via an external communication means (not shown) (S101). The transferred information is displayed in a list at the input / output unit 33 (S102), and the engineer as the user confirms the information (S103), and plans a rough schedule for the round trip taking into account the priority and travel route ( S104). The displayed contents include patient information such as patient name, sex, hospital room number, imaging requirements such as imaging site and imaging posture. Then, the AC cable is removed in accordance with the completion of charging (S105). If the photographing unit 10 is not mounted on the main body 21, it is mounted (S106).
準備が整うと、ユーザは、予定されたスケジュールに沿って移動型撮影装置20を押しながら所定の病室に移動開始する(S107)。このとき、無線制限を認識するための制御フラグNfのカウンタ値を0にリセットする。移動型撮影装置20は、移動中にゲートを通過をモニタしている(S108)。ゲート通過を検知した場合(S108でYES)はS109へ進み、ゲート通過を検知しなかった場合(S108でNO)はS110へ進む。本実施形態では、ゲート通過に応じて、受信手段36が、ゲート40の発信手段41から制限区域切換え信号を受信すると(S108でYES)、制御部32へ伝達され、制御部32内で、カウンタ値Nfに1加算する(S109)。カウンタ値Nfは2値のフラグであり、Nf=1の場合に1加算されると、Nf=0となる。
When the preparation is completed, the user starts moving to a predetermined hospital room while pushing the mobile imaging device 20 in accordance with the scheduled schedule (S107). At this time, the counter value of the control flag Nf for recognizing the radio restriction is reset to zero. The mobile imaging device 20 monitors the passage through the gate during movement (S108). If the passage of the gate is detected (YES in S108), the process proceeds to S109. If the passage of the gate is not detected (NO in S108), the process proceeds to S110. In the present embodiment, when the receiving unit 36 receives the restricted area switching signal from the transmitting unit 41 of the gate 40 in response to the passage of the gate (YES in S108), the signal is transmitted to the control unit 32, and in the control unit 32, the counter 1 is added to the value Nf (S109). The counter value Nf is a binary flag. If 1 is added when Nf = 1, Nf = 0.
次に、S110でカウンタ値Nfの値が1であるか否かを判定する(S110)。Nf=1の場合(S110でYES)は無線通信の制限を行い(S111)、S115へ進む。Nf=0の場合(S110でNO)は無線通信の制限を解除し(S112)、撮影(S113)を可能にする。
Next, in S110, it is determined whether or not the counter value Nf is 1 (S110). When Nf = 1 (YES in S110), wireless communication is restricted (S111), and the process proceeds to S115. When Nf = 0 (NO in S110), the restriction on wireless communication is released (S112), and photographing (S113) is enabled.
例えば、移動型撮影装置20が他のフロアの撮影基地からエレベータを使って図4のフロアのエレベータ出入口45から出た場合を考える。基地を出た時にはNf=0であるが、図4のフロアに到達するまでに制限区域切換え信号を受信して、カウンタ値Nfに1をセットし、無線制限されたNf=1の状態で図4のフロアに移動したとする。エレベータホールを含む通路区域は無線の影響が強い区域A1に隣接しているので、まだ無線制限を維持したままの移動となる。病棟A2での回診撮影をするため、さらに移動するとゲート40が配置されており、ゲート40から制限区域切換え信号を得るとカウンタ値はNf=0になり、無線制限が解除される。このように、無線制限区域からの退出を認識したことに応じて、無線通信機能の制限を解除するので、これ以降、無線通信が再び可能になる。例えば、無線通信が制限された状態で撮影された画像をまとめてサーバ装置へ送信することができる。
For example, let us consider a case where the mobile imaging device 20 exits from the elevator entrance 45 on the floor in FIG. 4 using an elevator from a photography base on another floor. When Nf = 0 when leaving the base, a restricted area switching signal is received by the time the floor of FIG. 4 is reached, the counter value Nf is set to 1, and the wireless limit Nf = 1 is set. Suppose we moved to the 4th floor. Since the passage area including the elevator hall is adjacent to the area A1 where the influence of radio is strong, the movement is still performed with the radio restriction maintained. In order to take a round trip in the ward A2, the gate 40 is arranged when moving further. When a restricted area switching signal is obtained from the gate 40, the counter value becomes Nf = 0, and the wireless restriction is released. As described above, since the restriction of the wireless communication function is released in response to the recognition of the exit from the wireless restricted area, wireless communication can be performed again thereafter. For example, it is possible to collectively transmit images taken in a state where wireless communication is restricted to the server device.
なお、無線通信を制限する手法としては、例えば、無線通信機能を無効化することの他に、無線通信機能が通信を行える時間帯や、通信の間隔、通信データ量、通信電力を一定の範囲に制限することが考えられる。システム設計者は、無線制限区域に求められる要件に応じて、適切な制限手法を選択することができる。
As a method for restricting wireless communication, for example, in addition to disabling the wireless communication function, a time range in which the wireless communication function can perform communication, a communication interval, communication data amount, and communication power are within a certain range. It is conceivable to limit to The system designer can select an appropriate restriction technique according to the requirements for the wireless restricted area.
こうして所定の病室に到着し停止すると、放射線発生部28を所定の撮影姿勢に対して位置調整したのち、表示部上の撮影部位を選択し、発生装置の管電圧やmAS値等の撮影条件を設定する。条件が整うと、撮影が実行される(S113)。撮影が終了すると撮影部10は収納部30に戻され、管理情報として撮影済であることが反映されリストが自動更新される(S114)。撮影オーダーをチェックし(S115)、オーダーが残っている場合(S115で「残」)は、次の病室へ移動し、一連のフローを繰り返す。撮影オーダーがなくなると(S115で「無」)、移動型撮影装置20は所定の待機基地に返却される。移動型撮影装置20が基地に到着すると(S116でYES)、同時にRISに撮影オーダーの処理結果を出力し(S117)、回診撮影は終了となる。
After arriving and stopping in a predetermined room in this manner, the radiation generating unit 28 is adjusted with respect to a predetermined imaging posture, and then an imaging region on the display unit is selected, and imaging conditions such as the tube voltage and mAS value of the generator are selected. Set. When the conditions are met, shooting is performed (S113). When shooting is completed, the shooting unit 10 is returned to the storage unit 30, and the list is automatically updated to reflect that shooting has been completed as management information (S114). The imaging order is checked (S115), and if the order remains ("Remaining" in S115), it moves to the next hospital room and repeats a series of flows. When there is no shooting order (“No” in S115), the mobile imaging device 20 is returned to a predetermined standby base. When the mobile imaging device 20 arrives at the base (YES in S116), the imaging order processing result is simultaneously output to the RIS (S117), and the round imaging is terminated.
以上のように、本実施形態の移動型撮影装置20(撮影装置)は、無線制限区域を特定する情報を取得する取得手段と、取得手段によって取得された情報に応じて無線通信機能を制限する制御手段とを備える。当該撮影装置が無線制限区域に侵入したことを認識したことに応じて、無線通信機能を制限する。このため、本実施形態の構成によれば、ユーザが無線制限区域への立ち入りを確認して無線通信機能を無効化するなど煩雑な作業を要することなく、無線通信を適切に制限することができる。なお、本実施形態では、無線通信機能を有する医療用の撮影装置の一例として移動型放射線撮影装置の構成例を説明したが、これに限られるわけではなく、無線通信機能を備えた他の種類の医療機器に適用可能であることはいうまでもない。
As described above, the mobile imaging device 20 (imaging device) of the present embodiment limits the wireless communication function according to the acquisition unit that acquires information for specifying the wireless restricted area and the information acquired by the acquisition unit. Control means. In response to recognizing that the photographing apparatus has entered the wireless restricted area, the wireless communication function is restricted. For this reason, according to the configuration of the present embodiment, it is possible to appropriately restrict wireless communication without requiring a complicated operation such as a user confirming access to the wireless restricted area and invalidating the wireless communication function. . In this embodiment, the configuration example of the mobile radiation imaging apparatus has been described as an example of a medical imaging apparatus having a wireless communication function. However, the present invention is not limited to this, and other types having a wireless communication function are available. Needless to say, it can be applied to other medical devices.
<<実施形態2>>
実施形態1では、ゲートに設けられた発信手段から制限区域切替え信号を受信することによって、無線通信制御区域を認識する構成例を説明した。本実施形態では、検知手段25による車輪24の回転検出結果等に基づいて現在位置を認識し、無線通信制御区域への侵入を判定する構成例を説明する。図6は、本発明の第2の実施形態に係る移動型撮影装置(移動型放射線撮影装置)の構成例を示す図である。本実施形態に係る構成の多くは実施形態1の構成と同様であるため、実施形態1との相違点を中心に説明する。 <<Embodiment 2 >>
In the first embodiment, the configuration example has been described in which the radio communication control area is recognized by receiving the restricted area switching signal from the transmission means provided in the gate. In the present embodiment, a configuration example will be described in which the current position is recognized based on the rotation detection result of thewheel 24 by the detection unit 25 and the intrusion into the wireless communication control area is determined. FIG. 6 is a diagram illustrating a configuration example of a mobile imaging apparatus (mobile radiation imaging apparatus) according to the second embodiment of the present invention. Since many of the configurations according to the present embodiment are the same as the configurations of the first embodiment, differences from the first embodiment will be mainly described.

In the first embodiment, the configuration example has been described in which the radio communication control area is recognized by receiving the restricted area switching signal from the transmission means provided in the gate. In the present embodiment, a configuration example will be described in which the current position is recognized based on the rotation detection result of the
図6には、このような撮影部10と組み合わされる移動型撮影装置が50として図示されている。移動型撮影装置50の本体21内部には現在位置を把握するための現在位置認識手段51が設けられており、制御部32に対して、逐次、現在地に関する情報を伝達する。現在位置認識手段51は、移動手段としての車輪24の回転を検出する検知手段25と、移動方向を検知する検知手段52と、重力方向へ移動を検知する検知手段53と、からの情報をもとに、相対的な位置変化や移動量を計算し、現在地を認識する。このように、現在位置認識手段51は、検出された移動型撮影装置50の移動量に基づいて現在地を判定し、当該現在地が無線制限区域に属すると判定される場合に、無線制限区域への侵入を認識する。このように、本実施形態では、移動型撮影装置20は、移動型撮影装置50の移動量に基づいて無線制限区域を特定する情報を取得し、当該情報に応じて無線通信機能を制限している。なお、このような情報は、後述するように、GPS信号やネットワーク網からの情報等に基づいて取得してもよい。
In FIG. 6, a movable photographing apparatus combined with such a photographing unit 10 is illustrated as 50. A current position recognizing means 51 for grasping the current position is provided inside the main body 21 of the mobile photographing device 50, and sequentially transmits information on the current location to the control unit 32. The current position recognizing means 51 includes information from a detecting means 25 for detecting the rotation of the wheel 24 as a moving means, a detecting means 52 for detecting the moving direction, and a detecting means 53 for detecting movement in the direction of gravity. And the relative position change and movement amount are calculated and the present location is recognized. As described above, the current position recognizing unit 51 determines the current location based on the detected movement amount of the mobile imaging device 50, and when it is determined that the current location belongs to the wireless restricted area, Recognize intrusions. As described above, in the present embodiment, the mobile imaging device 20 acquires information for specifying the wireless restricted area based on the movement amount of the mobile imaging device 50, and restricts the wireless communication function according to the information. Yes. Such information may be acquired based on a GPS signal, information from a network, or the like, as will be described later.
一方、実施形態1と同様に、本体21上部には、モニタと入力デバイスからなる入出力部33が設けられている。入出力部33は無線制限区域を設定するために用いられうる。制御部32には院内のマップ情報が保存されており、図7に示すように入出力モニタ60上にマップを表示する機能を有している。マップはフロア毎に作成されており、タブ61により切り替えて確認することが可能である。また、無線の制御区域情報を入力、編集できる機能を有しており、編集ボタン62の選択に応じて、入力、編集モードに遷移することが可能である。図7のように無線禁止区域A1を斜線部(ハッチング)のように定義することで無線制限区域の定義ができる。このように、所定の区域の地図をモニタに表示し、当該地図においてユーザからの選択を受け付ける受付処理を行い、ユーザから選択された区域を無線制限区域として設定することで、ユーザは簡易な操作で無線制限区域を設定することができる。
On the other hand, as in the first embodiment, an input / output unit 33 including a monitor and an input device is provided on the upper portion of the main body 21. The input / output unit 33 can be used to set a wireless restricted area. The controller 32 stores in-hospital map information and has a function of displaying a map on the input / output monitor 60 as shown in FIG. The map is created for each floor, and can be confirmed by switching on the tab 61. In addition, it has a function of inputting and editing wireless control area information, and it is possible to shift to the input / edit mode according to the selection of the edit button 62. As shown in FIG. 7, the wireless restricted area can be defined by defining the wireless prohibited area A1 as a hatched portion (hatched). As described above, the map of the predetermined area is displayed on the monitor, the reception process for accepting the selection from the user on the map is performed, and the area selected by the user is set as the wireless restricted area, so that the user can perform a simple operation. A wireless restricted area can be set.
また、無線制限も無線通信を無効化するレベルや無線通信の頻度を抑えるレベル等を段階的に定義することも可能である。すなわち、無線制限区域を無線通信を制限すべきレベルがそれぞれ割り当てられた部分区域から構成し、撮影装置が存在する部分区域に割り当てられているレベルに応じて、無線通信機能を制限するレベルを制御するように構成することができる。これにより、無線通信を制限すべきレベルに応じてきめ細かく無線通信を制限することができる。
Also, it is possible to define the level of wireless restriction in stages, such as the level of invalidating wireless communication and the level of suppressing the frequency of wireless communication. In other words, the wireless restricted area is composed of partial areas each assigned a level that should restrict wireless communication, and the level for restricting the wireless communication function is controlled according to the level assigned to the partial area where the imaging device exists. Can be configured to. As a result, the wireless communication can be finely restricted according to the level at which the wireless communication should be restricted.
また、入出力モニタ60上には現在地を表示するマーカ63が表示され、無線制限区域との位置関係をモニタ上でも確認することが可能である。あらかじめ無線制限のルール設定ができ、例えば無線禁止区域に対して半径何m以内に近づくと無線通信を制限したり、無線禁止区域に現に侵入した際は無線通信を止めるといった管理が可能になる。このような機能を有することで、操作者が意識せずに自動的に無線通信の管理ができ、無線通信によるトラブルを防ぐことができる。
Also, a marker 63 for displaying the current location is displayed on the input / output monitor 60, and the positional relationship with the wireless restricted area can be confirmed on the monitor. Wireless restriction rules can be set in advance. For example, it is possible to manage such as restricting wireless communication when the radius approaches a wireless prohibited area, or stopping wireless communication when the wireless prohibited area is actually entered. By having such a function, it is possible to automatically manage wireless communication without the operator being aware of it, and to prevent troubles due to wireless communication.
前述の無線通信の頻度を抑えるレベルの設定により、無線通信を無効化するのではなく、通信頻度を抑えるような制御をルール化することで、情報更新に対する時間的な遅れが軽減されるので、緊急のオーダー追加等への対応の柔軟性が向上できる。
By setting the level to reduce the frequency of wireless communication as described above, the time delay for information update can be reduced by creating a rule that suppresses the communication frequency instead of invalidating the wireless communication. Flexibility in responding to urgent order additions can be improved.
<<実施形態3>>
図8に示される第3の実施形態は、実施形態2の変形例である。実施形態2と共通の部分に関しては同じ符号にて記述する。実施形態2の移動型放射線撮影装置では、測位手段として現在位置認識手段51を使用した。これは車輪24の回転を検出したり、移動方向や重力方向へ移動を検知する各検知手段により、移動からの情報をもとに、自ら相対的な位置変化を計算し、現在地を得る自律航法型の測位手段であった。現在では測位技術も進歩し、GPSのように衛星からの信号を利用した測位手段や無線ネットワーク網を利用した測位手段が一般的に使用され、検知位置精度も向上している。本実施形態における図8の移動型放射線撮影装置では、このような電波を利用した測位手段71を搭載している。 <<Embodiment 3 >>
The third embodiment shown in FIG. 8 is a modification of the second embodiment. Portions common to the second embodiment are described with the same reference numerals. In the mobile radiation imaging apparatus according to the second embodiment, the currentposition recognition unit 51 is used as the positioning unit. This is an autonomous navigation system that detects the rotation of the wheel 24, calculates the relative position change by itself based on the information from the movement, and obtains the current position by each detecting means for detecting the movement in the moving direction and the gravitational direction. It was a type of positioning means. At present, positioning technology has advanced, and positioning means using a signal from a satellite and positioning means using a wireless network such as GPS are generally used, and the detection position accuracy is also improved. The mobile radiography apparatus of FIG. 8 in this embodiment is equipped with positioning means 71 using such radio waves.

The third embodiment shown in FIG. 8 is a modification of the second embodiment. Portions common to the second embodiment are described with the same reference numerals. In the mobile radiation imaging apparatus according to the second embodiment, the current
前述した自律航法型の測位手段の場合、相対位置を計算して積算していくため、徐々に位置誤差が発生する可能性があり、かなり精度良い検出能が必要である。これに対して電波を利用した測位手段は、既知の位置からの相対位置検出をその都度行うため、誤差の積み上げは少ない。通常はこの電波を利用した測位手段を利用することで、精度よく位置把握ができる。しかし、無線制限がある場合は使用制限されるため、位置検出精度が落ちてしまう。その際は、自律航法型として現在位置認識手段51を使用する。無線制限が解除されたところで電波による測位手段を使用することで、位置を補正することができる。
In the case of the above-mentioned autonomous navigation type positioning means, the relative position is calculated and accumulated, so that a position error may gradually occur, and a detection capability with a very high accuracy is required. On the other hand, since the positioning means using radio waves detects the relative position from a known position each time, the accumulation of errors is small. Usually, the position can be accurately grasped by using a positioning means using this radio wave. However, if there is a radio restriction, the use is restricted, and the position detection accuracy is lowered. In that case, the current position recognition means 51 is used as an autonomous navigation type. The position can be corrected by using a positioning means using radio waves when the wireless restriction is released.
このように、本実施形態では、測位手段として、受信した電波により位置を計測する計測手段と、自律航法型の測位手段とを有し、撮影装置が無線制限区域に侵入していると認識されている間は、自律航法型の測位手段のみを使用する。このため、無線制限区域における無線通信の制限と、現在地の正確な把握とを両立することが可能となる。
As described above, in the present embodiment, the positioning unit includes a measuring unit that measures a position using the received radio wave and an autonomous navigation type positioning unit, and the imaging apparatus is recognized as entering the wireless restricted area. While using it, only use autonomous navigation type positioning means. For this reason, it becomes possible to achieve both the restriction of wireless communication in the wireless restricted area and the accurate grasp of the current location.
以上の各実施形態によれば、操作者が意識せずとも無線制限を遵守し院内の他装置への影響を抑制できる。なお、上述の実施の形態の放射線画像撮影装置は、特許請求の範囲を逸脱することなく、多様に変形することが可能であることはいうまでもない。
According to each of the above-described embodiments, it is possible to observe the wireless restriction and suppress the influence on other devices in the hospital without being conscious of the operator. In addition, it cannot be overemphasized that the radiographic imaging apparatus of the above-mentioned embodiment can be variously deformed, without deviating from a claim.
以下、図10乃至図19を参照して、本発明の実施形態4乃至実施形態6について説明する。

図10は、実施形態4にかかる撮影部10aの側面断面図である。ここでは、撮影部10aとして電子カセッテを示す。図10に示すように、撮影部10aは、筺体1005と放射線検出パネル1001とを含み放射線管からの放射線を受けて放射線画像を得る撮影部あるいは放射線検出器である。筺体1005は、筺体本体1501と筺体蓋1502とから構成される。そして、筺体1005に放射線検出パネル1001やその他の機器などが内蔵される。なお、筺体蓋1502は、放射線を透過する材料により形成される。放射線検出パネル1001は、基板1101と、光電変換素子1102と、蛍光板1103とで構成される。基板1101は、半導体素子との化学作用のないこと、半導体プロセスの温度に耐えること、寸法安定性などの必要性から、ガラス基板が好適に用いられる。そしてガラス基板には、光電変換素子1102が、半導体プロセスによりマトリクス状に形成される。蛍光板1103は、金属化合物の蛍光体が樹脂板に塗布された構成を有する。また、蛍光板1103は、基板1101と接着されて一体化されている。そして、放射線検出パネル1001は、金属製の基台1002に固定支持されることにより、機械的強度が確保されている。なお、基台1002は、支持部1201を介して筺体本体1501の内部に固定されている。回路基板1003には、光電変換素子1102により変換された電気信号を処理する電子部品1301と、光電変換素子1102を駆動する駆動回路が実装されている。そして、回路基板1003は、フレキシブル回路基板1004によって、光電変換素子1102と接続されている。また、回路基板1003は、基台1002の裏側に設けられた突起1202に固定されている。 <<Embodiment 4 >>
FIG. 10 is a side sectional view of theimaging unit 10a according to the fourth embodiment. Here, an electronic cassette is shown as the photographing unit 10a. As illustrated in FIG. 10, the imaging unit 10 a is an imaging unit or a radiation detector that includes a housing 1005 and a radiation detection panel 1001 and receives radiation from a radiation tube to obtain a radiation image. The housing 1005 includes a housing body 1501 and a housing lid 1502. The housing 1005 incorporates the radiation detection panel 1001 and other devices. Note that the casing lid 1502 is formed of a material that transmits radiation. The radiation detection panel 1001 includes a substrate 1101, a photoelectric conversion element 1102, and a fluorescent plate 1103.

FIG. 12 is a schematic diagram of an example of a hospital layout in which the radiation imaging apparatus 20a is used. In the hospital, a wireless prohibited area A121, wireless available areas A122 and A123, and a switching preparation area A124 are set in advance. The wireless prohibited area A121 is a space where devices that are easily affected by wireless communication are installed, and is an area where wireless communication by the radiation imaging apparatus 20a is prohibited. Wireless possible areas A122 and A123 are areas where wireless communication by the radiation imaging apparatus 20a is permitted. The hospital room of the inpatient is set in the wireless available areas A122 and A123 because wireless communication is required for round-trip imaging. The switching preparation area A124 is an area that is neither the wireless prohibition area A121 nor the radio-capable areas A122, A123, and is provided in a route through which the radio-prohibited area A121 and the radio-capable areas A122, A123 move to each other. Area. That is, the switching preparation area A124 is provided adjacent to the wireless prohibited area A121 on the route to the wireless prohibited area A121.
そして、各区域A121~A124の入り口またはその近傍には、ゲート1240,1242,1243,1244が配置される。図13は、ゲート1240,1242,1243,1244の構成の例を示す模式図である。たとえば、ゲート1240,1242,1243,1244は、設備の壁面に設けられる。それぞれのゲート1240,1242,1243,1244は、信号発信部1341を有する。信号発信部1341は、区域A121~A124の種類に応じて、無線制限を認識するための信号を無線で発信する。

FIG. 13 is a schematic diagram showing an example of the configuration of the gates 1240, 1242, 1243, 1244. For example, the gates 1240, 1242, 1243, and 1244 are provided on the wall surface of the facility. Each gate 1240, 1242, 1243, 1244 has a signal transmission unit 1341. The signal transmission unit 1341 wirelessly transmits a signal for recognizing the wireless restriction according to the types of the areas A121 to A124.
放射線撮影装置20aの信号受信部1136は、ゲート1240,1242,1243,1244に接近すると、信号発信部1341が発する信号を受信する。そして、放射線撮影装置20aの制御部1132は、信号受信部1136により受信した信号から、放射線撮影装置20aとゲート1240,1242,1243,1244との接近の程度の検出や、所定距離に接近したかを検出できる。すなわち、信号発信部1341と信号受信部1136との組み合わせを用いることによって、制御部1132は、ゲート1240,1242,1243,1244に最も接近した時が、放射線撮影装置20aがゲート1240,1242,1243,1244を通過した時であると判定できる。
When the signal receiving unit 1136 of the radiation imaging apparatus 20a approaches the gates 1240, 1242, 1243, and 1244, the signal receiving unit 1341 receives a signal. Then, the control unit 1132 of the radiation imaging apparatus 20a detects the degree of proximity between the radiation imaging apparatus 20a and the gates 1240, 1242, 1243, and 1244 from the signal received by the signal reception unit 1136, or has the proximity approached a predetermined distance? Can be detected. That is, by using a combination of the signal transmission unit 1341 and the signal reception unit 1136, when the control unit 1132 is closest to the gates 1240, 1242, 1243, 1244, the radiation imaging apparatus 20 a is connected to the gates 1240, 1242, 1243. , 1244 can be determined.
このように、放射線撮影装置20aと、放射線撮影装置20aに対して無線制限を認識するための信号を無線で発信する信号発信部1341とによって、放射線撮影システムが構築される。そして、この放射線撮影システムにおいて、放射線撮影装置20aは、ゲート1240,1242,1243,1244の信号発信部1341が発する無線制限を認識するための信号を受信することによって、現在位置や各区域A121~A124との位置関係を判定できる。さらに、放射線撮影装置20aは、各区域A121~A124との接近の程度や、所定距離に接近したかを判定できる。そして、制御部1132は、現在位置(各区域A121~A124との位置関係)に応じて、外部通信部1134と無線通信部1135による無線通信の制限または制限の解除を行う。
As described above, the radiation imaging system is constructed by the radiation imaging apparatus 20a and the signal transmission unit 1341 that wirelessly transmits a signal for recognizing the wireless restriction to the radiation imaging apparatus 20a. In this radiation imaging system, the radiation imaging apparatus 20a receives a signal for recognizing the radio restriction generated by the signal transmission unit 1341 of the gates 1240, 1242, 1243, and 1244, so that the current position and each of the areas A121 to A121. The positional relationship with A124 can be determined. Further, the radiation imaging apparatus 20a can determine the degree of approach to each of the areas A121 to A124 and whether or not it has approached a predetermined distance. Then, the control unit 1132 performs restriction or cancellation of wireless communication by the external communication unit 1134 and the wireless communication unit 1135 according to the current position (positional relationship with each of the areas A121 to A124).
次に、放射線撮影装置20aを回診に使用する際のワークフローについて、図14A、図14Bを参照して説明する。図14A、図14Bは、放射線撮影装置20aの処理を示すフローチャートである。なお、使用者は、放射線撮影装置20aの使用の準備として、放射線撮影装置20aに電力を供給して稼働させるためのACケーブル(図略)を商用電源に接続し、本体バッテリ1131を充電しておく。さらに、放射線撮影装置20aの収納部1130に、撮影部10aが収納されているものとする。

Furthermore, the imaging unit 10a is stored in the storage unit 1130 of the radiation imaging apparatus 20a.
以下に示す例では、ゲート1240,1242,1243,1244の信号発信部1341は、無線制限を認識するための信号として、区域の種類に応じたフラグ値Fe(またはフラグ値Feの切替え信号)を無線で発信している。そして、無線禁止区域A121のフラグ値Feには「2」が割り当てられ、無線可能区域A122,A123のフラグ値Feには「0」が割り当てられ、切替準備区域A124のフラグ値Feには「1」が割り当てられているものとする。一方、制御部1132は、区域の種類を管理するためにフラグ値Feを管理(保持)する演算部を有するものとする。そして、制御部1132は、フラグ値Feにより区域A121~A124との位置関係を認識し、フラグ値Feに応じた条件分岐により、区域A121~A124に応じた処理を実行する。
In the example shown below, the signal transmission unit 1341 of the gates 1240, 1242, 1243, and 1244 uses a flag value Fe (or a flag value Fe switching signal) corresponding to the type of area as a signal for recognizing the radio restriction. Sending wirelessly. Then, “2” is assigned to the flag value Fe of the radio prohibited area A121, “0” is assigned to the flag value Fe of the radio feasible areas A122 and A123, and “1” is assigned to the flag value Fe of the switch preparation area A124. "Is assigned. On the other hand, it is assumed that the control unit 1132 includes a calculation unit that manages (holds) the flag value Fe in order to manage the type of area. Then, the control unit 1132 recognizes the positional relationship with the areas A121 to A124 based on the flag value Fe, and executes processing according to the areas A121 to A124 by conditional branching according to the flag value Fe.
ステップS1401において、制御部1132は、入出力部1133に対して回診のオーダー情報を取得するための操作が行われたか否かを判定する。そして、制御部1132は、オーダー情報の取得操作があるまで待機する。取得のための操作があった場合にはステップS1402に進む。
In step S <b> 1401, the control unit 1132 determines whether or not an operation for obtaining order information for round trips has been performed on the input / output unit 1133. Then, the control unit 1132 stands by until there is an order information acquisition operation. If there is an operation for acquisition, the process proceeds to step S1402.
ステップS1402では、制御部1132は、院内の外部端末から外部通信部1134を介してオーダー情報を取得し、入出力部1133のモニタに取得したオーダー情報を表示する。入出力部1133のモニタに表示するオーダー情報としては、患者氏名や性別などの患者情報や病室番号、撮影部位や撮影姿勢等の撮影条件などである。したがって使用者は、モニタに表示されるオーダー情報を確認し、撮影の優先度や移動ルートを考慮して回診撮影の大まかなスケジュールを計画できる。そして、使用者は、計画したスケジュールに沿って放射線撮影装置20aとともに、回診する病室に移動を開始することになる。
In step S1402, the control unit 1132 acquires order information from an external terminal in the hospital via the external communication unit 1134, and displays the acquired order information on the monitor of the input / output unit 1133. The order information displayed on the monitor of the input / output unit 1133 includes patient information such as a patient name and sex, a room number, a photographing condition such as a photographing part and a photographing posture, and the like. Therefore, the user can check the order information displayed on the monitor, and can plan a rough schedule for the round-trip imaging in consideration of the imaging priority and the moving route. And a user will start a movement to the hospital room to go round with the radiography apparatus 20a along the planned schedule.
ステップS1403において、制御部1132は、保持しているフラグ値Feを「0」に初期化する。
In step S1403, the control unit 1132 initializes the held flag value Fe to “0”.
ステップS1404において、放射線撮影装置20aがゲート1240,1242,1243,1244を通過したか否かを判定する。すなわち、まず、制御部1132は、信号受信部1136によってゲート1240,1242,1243,1244の信号発信部1341が発信するフラグ値Feを受信したか否かを判定する。そして、受信した場合には放射線撮影装置20aがゲート1240,1242,1243,1244に所定距離に接近したかを判定する。所定距離に接近した場合には、ゲート1240,1242,1243,1244を通過したと判定し、そうでない場合には、通過していないと判定する。ゲート1240,1242,1243,1244を通過した場合にはステップS1405に進み、接近していない場合にはステップS1405を経ずにステップS1406に進む。このように、放射線撮影装置20aの制御部1132は、移動中において、信号受信部1136によりフラグ値Feを受信したか否かと、ゲート1240,1242,1243,1244に所定距離に接近したかの判定を継続する。そして、所定距離に接近した場合には、制御部1132は、ゲート1240,1242,1243,1244を通過したと判定する。このようにして制御部1132は、ゲート1240,1242,1243,1244の通過をモニタリングする。なお、この所定距離の具体的な値は限定されるものではなく、適宜設定される。
In step S1404, it is determined whether or not the radiation imaging apparatus 20a has passed through the gates 1240, 1242, 1243, and 1244. That is, first, the control unit 1132 determines whether or not the signal reception unit 1136 has received the flag value Fe transmitted by the signal transmission unit 1341 of the gates 1240, 1242, 1243, and 1244. If it is received, it is determined whether the radiation imaging apparatus 20a has approached the gates 1240, 1242, 1243, and 1244 within a predetermined distance. When approaching a predetermined distance, it is determined that the gates 1240, 1242, 1243, and 1244 have passed, and otherwise, it is determined that they have not passed. If it has passed through the gates 1240, 1242, 1243, 1244, the process proceeds to step S1405. If not, the process proceeds to step S1406 without passing through step S1405. In this way, the control unit 1132 of the radiation imaging apparatus 20a determines whether or not the flag value Fe is received by the signal receiving unit 1136 and whether or not the gates 1240, 1242, 1243, and 1244 have approached a predetermined distance during movement. Continue. When approaching the predetermined distance, the controller 1132 determines that the gates 1240, 1242, 1243, 1244 have passed. In this way, the control unit 1132 monitors the passage of the gates 1240, 1242, 1243, and 1244. The specific value of the predetermined distance is not limited and is set as appropriate.
ステップS1405において、制御部1132は、現在保持しているフラグ値Feを、ステップS1404において受信したフラグ値Feに変更する。例えば、図12に示すように、エレベータEVの出入口には、ゲート1243が配置されているものとする。そして、このゲート1243の信号発信部1341は、フラグ値Feとして「1」を無線で発信している。すなわち、ゲート1243の信号発信部1341は、フラグ値Feを「1」へ切替える位置であることを報知している。このため、使用者が放射線撮影装置20aとともにエレベータEVを下り、ゲート1243を通過すると、制御部1132は、保持しているフラグ値Feを「1」に変更する。また、病室の区域への出入口には、ゲート1240,1244が配置されている。そして、ゲート1240,1244の信号発信部1341は、フラグ値Feとして「0」を無線で発信している。ゲート1242の信号発信部1341は、フラグ値Feとして「2」を無線で発信している。
In step S1405, the control unit 1132 changes the currently held flag value Fe to the flag value Fe received in step S1404. For example, as shown in FIG. 12, it is assumed that a gate 1243 is disposed at the entrance / exit of the elevator EV. The signal transmitter 1341 of the gate 1243 wirelessly transmits “1” as the flag value Fe. That is, the signal transmission unit 1341 of the gate 1243 notifies that it is a position where the flag value Fe is switched to “1”. Therefore, when the user goes down the elevator EV together with the radiation imaging apparatus 20a and passes through the gate 1243, the control unit 1132 changes the held flag value Fe to “1”. In addition, gates 1240 and 1244 are arranged at the entrance to the hospital room area. And the signal transmission part 1341 of the gates 1240 and 1244 is wirelessly transmitting “0” as the flag value Fe. The signal transmitter 1341 of the gate 1242 wirelessly transmits “2” as the flag value Fe.
ステップS1406において、制御部1132は、変更したフラグ値Feを判定する。フラグ値Feが「0」または「1」である場合にはステップS1407に進む。フラグ値Feが「2」である場合にはステップS1408に進む。
In step S1406, the control unit 1132 determines the changed flag value Fe. If the flag value Fe is “0” or “1”, the process proceeds to step S1407. If the flag value Fe is “2”, the process proceeds to step S1408.
ステップS1407に進んだ場合には、放射線撮影装置20aが無線可能区域A122,A123または切替準備区域A124に進入したため、制御部1132は、外部通信部1134と無線通信部1135の無線通信の制限(停止)を解除する。そして、ステップS1410に進む。
When the process proceeds to step S1407, since the radiation imaging apparatus 20a has entered the wireless available area A122, A123 or the switching preparation area A124, the control unit 1132 restricts (stops) wireless communication between the external communication unit 1134 and the wireless communication unit 1135. ). Then, the process proceeds to step S1410.
一方、ステップS1408に進んだ場合には、放射線撮影装置20aが無線禁止区域A121に進入したため、制御部1132は、外部通信部1134と無線通信部1135の無線通信を制限する(使用を停止する)。そして、ステップS1409に進む。ステップS1409においては、制御部1132は、入出力部1133のモニタに、放射線撮影装置20aが無線禁止区域A121に入ったこと、および、外部通信部1134と無線通信部1135の無線通信を制限したこと(使用を停止したこと)を使用者に報知する処理を行う。たとえば、これらを音声により報知したり、モニタに表示したりする。そして、ステップS1404に戻る。
On the other hand, when the process proceeds to step S1408, since the radiographic apparatus 20a has entered the wireless prohibited area A121, the control unit 1132 restricts wireless communication between the external communication unit 1134 and the wireless communication unit 1135 (stops use). . Then, the process proceeds to step S1409. In step S1409, the control unit 1132 indicates that the radiation imaging apparatus 20a has entered the wireless prohibited area A121 and that the wireless communication between the external communication unit 1134 and the wireless communication unit 1135 is restricted on the monitor of the input / output unit 1133. A process of notifying the user that (use has been stopped) is performed. For example, these are notified by voice or displayed on a monitor. Then, the process returns to step S1404.
ステップS1410において、制御部1132は、現在保持しているフラグ値Feが「0」であるか否かを判定する。フラグ値Feが「0」でない場合にはステップS1411に進む。フラグ値Feが「0」である場合にはステップS1413に進む。
In step S1410, the control unit 1132 determines whether or not the currently held flag value Fe is “0”. If the flag value Fe is not “0”, the process proceeds to step S1411. If the flag value Fe is “0”, the process proceeds to step S1413.
ステップS1411に進んだ場合には、放射線撮影装置20aは無線禁止区域A121に隣接した切替準備区域A124に進入したため、制御部1132は、無線制限に対応するための処理(無線通信制限前処理)を実行する。具体的には、制御部1132は、外部通信部1134を介して院内の外部端末に対して自動的に緊急の新規撮影オーダーの問い合わせや、画像転送の優先案件の確認等を行う。無線制限に対応するための処理が終了すると、ステップS1412に進む。
When the process proceeds to step S1411, since the radiographic apparatus 20a has entered the switching preparation area A124 adjacent to the wireless prohibition area A121, the control unit 1132 performs a process (wireless communication restriction pre-processing) to cope with the wireless restriction. Execute. Specifically, the control unit 1132 automatically makes an inquiry about an urgent new imaging order, confirms an image transfer priority case, and the like to an external terminal in the hospital via the external communication unit 1134. When the process for responding to the wireless restriction is completed, the process proceeds to step S1412.
ステップS1412においては、制御部1132は、無線制限に対応するための処理を完了したことを報知する処理を行う。たとえばその旨をモニタに表示するか、または音声で報知する。なお、画像転送の優先案件があった場合には、モニタにその旨のメッセージを表示するか、または音声による報知を行う。さらに、制御部1132は、放射線撮影装置20aが無線禁止区域A121に接近しいている旨のメッセージをモニタに表示させるか、またはその旨を音声で報知する。これにより使用者は、その場で優先案件に係る画像転送の操作を実行するか、移動を継続するかを選択できる。また、優先案件に係る画像転送は、使用者の操作に基づくものではなく、制御部1132が自動で実行してもよい。すなわち、画像転送の優先案件が存在した場合には、制御部1132は、優先案件にかかる画像について優先度を判定し、優先度の高い順から外部端末に送信してもよい。
In step S1412, the control unit 1132 performs processing for notifying that processing for responding to the wireless restriction has been completed. For example, the fact is displayed on the monitor or notified by voice. If there is a priority case for image transfer, a message to that effect is displayed on the monitor or a voice notification is given. Furthermore, the control unit 1132 displays a message indicating that the radiation imaging apparatus 20a is approaching the wireless prohibited area A121 on the monitor, or notifies the fact by voice. Thereby, the user can select whether to execute the image transfer operation related to the priority item on the spot or to continue the movement. Further, the image transfer related to the priority item is not based on the operation of the user, and may be automatically executed by the control unit 1132. That is, when there is a priority case for image transfer, the control unit 1132 may determine the priority of the image related to the priority case, and transmit the priority to the external terminal in descending order of priority.
またステップS1411において、制御部1132は、無線制限に対応するための処理として、撮影部10aの通信部1007を介して、撮影部10aの状態に関する情報を収集する。状態に関する情報としてはバッテリ1006の状態(バッテリ1006の充電率など)、放射線検出パネル1001の駆動状態、内部温度の情報のいずれかまたは全部である。制御部1132は、収集した情報から、撮影に障害になるような情報の確認を行う。そしてステップS1412において、制御部1132は、必要であれば所定の対処を促すようなメッセージを表示するか、または音声により報知する。これにより、制御部1132は、無線制限に対応するための処理が完了したことを、使用者に報知する。
Also, in step S1411, the control unit 1132 collects information regarding the state of the imaging unit 10a via the communication unit 1007 of the imaging unit 10a as a process for dealing with wireless restriction. Information on the state includes any or all of information on the state of the battery 1006 (such as the charging rate of the battery 1006), the driving state of the radiation detection panel 1001, and the internal temperature. The control unit 1132 confirms information from the collected information that may interfere with shooting. In step S1412, the control unit 1132 displays a message that prompts a predetermined countermeasure if necessary, or notifies by voice. As a result, the control unit 1132 notifies the user that the processing for responding to the wireless restriction has been completed.
なお、放射線撮影装置20aが、無線禁止区域A121から退出し、ゲート1242を通過して切替準備区域A124に進入した場合には、制御部1132は、外部通信部1134と無線通信部1135の無線通信の制限を解除する。さらに、制御部1132は、無線禁止区域A121から退出した場合には、上述のようなオーダー情報や撮影部の状態情報を確認する処理を行い、状況に変化があった場合はメッセージを表示もしくは報知を行う。また、画像転送の優先案件が存在する場合には、制御部1132は、外部端末に対して、優先案件に係る画像のデータを送信してもよい。
In addition, when the radiation imaging apparatus 20a exits from the wireless prohibited area A121, passes through the gate 1242, and enters the switching preparation area A124, the control unit 1132 performs wireless communication between the external communication unit 1134 and the wireless communication unit 1135. Remove the restrictions. Furthermore, when the control unit 1132 leaves the wireless prohibited area A121, the control unit 1132 performs processing for confirming the order information and the state information of the photographing unit as described above, and displays or notifies a message when the situation changes. I do. Further, when there is a priority item for image transfer, the control unit 1132 may transmit image data related to the priority item to the external terminal.
ステップS1413において、制御部1132は、入出力部1133に対して撮影の実行を指示する操作があったか否かを判定する。そして、操作があった場合には、ステップS1414に進む。操作がない場合には、ステップS1404に戻る。
In step S1413, the control unit 1132 determines whether or not there has been an operation for instructing the input / output unit 1133 to execute shooting. If there is an operation, the process proceeds to step S1414. If there is no operation, the process returns to step S1404.
ステップS1414においては、制御部1132は、操作に応じた撮影条件で放射線画像の撮影を実行する。すなわち使用者は、前述のように途中の区域を経て、無線可能区域A122,A123に所在する所定の病室に到着すると、放射線撮影装置20aの移動を停止させることになる。そして使用者は、放射線発生部1128を所定の撮影姿勢に対して位置調整したのち、入出力部1133に対して、撮影条件の設定と撮影の実行を指示する操作を行う。たとえば、使用者は、モニタに表示される撮影部位を選択し、発生装置の管電圧やmAS値等の撮影条件を設定する操作を行う。制御部1132は、撮影条件の設定と撮影の実行を指示する操作を受け付けると、操作に応じて撮影条件を設定し、放射線画像の撮影を実行する。
In step S <b> 1414, the control unit 1132 performs radiographic image capturing under imaging conditions corresponding to the operation. That is, the user stops moving the radiation imaging apparatus 20a when he / she arrives at a predetermined hospital room located in the wireless-capable areas A122 and A123 through an intermediate area as described above. The user adjusts the position of the radiation generating unit 1128 with respect to a predetermined imaging posture, and then performs an operation for instructing the input / output unit 1133 to set imaging conditions and execute imaging. For example, the user selects an imaging region displayed on the monitor and performs an operation of setting imaging conditions such as a tube voltage and a mAS value of the generator. When receiving an operation for instructing setting of imaging conditions and execution of imaging, the control unit 1132 sets imaging conditions according to the operation and executes imaging of a radiographic image.
ステップS1415において、制御部1132は、撮影部10aが収納部1130に収納されたか否かを判断する。収納された場合にはステップS1416に進む。収納されていない場合には、ステップS1415を繰り返す。ステップS1416において、制御部1132は、オーダー情報を更新するとともに、更新したオーダー情報をモニタに表示する。これにより使用者は、オーダーが残っているか否かを確認して、回診を継続するか終了するかを判断できる。ステップS1417において、制御部1132は、更新したオーダー情報について、撮影オーダーが残っているか否かを判断する。残っている場合には、ステップS1404に戻る。残っていない場合には、ステップS1418に進む。ステップS1418において、制御部1132は、放射線撮影装置20aが基地に返却されたか否かを判断する。返却された場合にはステップS1419に進む。返却されていない場合にはステップS1404に戻る。ステップS1419において、制御部1132は、外部通信部1134を介して院内の外部端末に撮影オーダーの結果を出力する。
In step S1415, the control unit 1132 determines whether or not the photographing unit 10a is stored in the storage unit 1130. If stored, the process advances to step S1416. If not, step S1415 is repeated. In step S1416, the control unit 1132 updates the order information and displays the updated order information on the monitor. Thus, the user can determine whether or not the order remains and can determine whether to continue or end the round. In step S1417, the control unit 1132 determines whether or not there is a shooting order for the updated order information. If it remains, the process returns to step S1404. If not, the process proceeds to step S1418. In step S1418, the control unit 1132 determines whether or not the radiation imaging apparatus 20a has been returned to the base. If it is returned, the process proceeds to step S1419. If it has not been returned, the process returns to step S1404. In step S1419, the control unit 1132 outputs the result of the imaging order to an external terminal in the hospital via the external communication unit 1134.
以上説明したとおり、本実施形態にかかる放射線撮影装置20aは、無線制限に関する区域の情報を認識し、無線制限する前の確認処理等の処理を事前に実行する。これにより、回診業務の効率の向上を図ることができる。また、本実施形態によれば、放射線撮影装置20aが、区域A121~A124に関する情報から無線通信の制限および制限の解除を実行する。このため、使用者が、区域A121~A124の種類に応じて無線の使用の制限および制限の解除の操作を行わなくてもよい。なお、本実施形態では、無線通信の制限と表示の両方を行う構成を示したが、いずれか一方のみを実行する構成であってもよい。
As described above, the radiation imaging apparatus 20a according to the present embodiment recognizes information on areas related to wireless restriction, and executes processing such as confirmation processing before wireless restriction in advance. As a result, the efficiency of the round-trip operation can be improved. Further, according to the present embodiment, the radiation imaging apparatus 20a executes wireless communication restriction and restriction release from information on the sections A121 to A124. For this reason, the user does not have to perform operations for restricting use of the radio and releasing the restriction according to the types of the areas A121 to A124. In the present embodiment, the configuration in which both the restriction and display of wireless communication are performed has been described, but the configuration in which only one of them is executed may be employed.

図15は、実施形態5にかかる撮影部10bの構成例を模式的に示す断面図である。撮影部10bには、回路基板1003などに対して電源供給を行うバッテリ1006と、画像信号や制御信号などの通信を無線で行う通信部1007とが設けられる。無線通信を行う場合には、撮影部10bの通信部1007は、バッテリ1006から給電を受けて動作し、通信部1007が内蔵する無線通信機能によって通信を行う。無線通信ではなく有線通信を行う場合には、使用者は、撮影部10bの筺体本体1501に設けられたコネクタ1008に、外部からケーブル1161を接続する。これにより、通信部1007は、放射線撮影装置20bの制御部1132と、ケーブル1161を介して直接給電と有線通信を行う。このため、電池切れや無線による通信の不安定さは解消される。
FIG. 15 is a cross-sectional view schematically illustrating a configuration example of the imaging unit 10b according to the fifth embodiment. The imaging unit 10b is provided with a battery 1006 that supplies power to the circuit board 1003 and the like, and a communication unit 1007 that wirelessly communicates image signals and control signals. When performing wireless communication, the communication unit 1007 of the photographing unit 10b operates by receiving power from the battery 1006, and performs communication using a wireless communication function built in the communication unit 1007. When performing wired communication instead of wireless communication, the user connects a cable 1161 from the outside to a connector 1008 provided on the housing body 1501 of the photographing unit 10b. Accordingly, the communication unit 1007 performs direct power feeding and wired communication with the control unit 1132 of the radiation imaging apparatus 20b via the cable 1161. As a result, battery instability and wireless communication instability are eliminated.
図16は、実施形態5に係る放射線撮影装置20bの構成例を示す模式図である。放射線撮影装置20bは、撮影部10bの通信部1007と専用に無線通信する無線通信部1135を有する。入出力部1133の入力デバイスが撮影条件を設定する操作を受け付けると、制御部1132は、設定された撮影条件での撮影指令を、無線通信部1135を介して撮影部10bに無線で送信する。撮影部10bは、受信した撮影指令に従い、放射線発生部1128と同期して放射線画像を撮影する。そして、撮影部10bは、撮影した放射線画像を、通信部1007を介して放射線撮影装置20bの制御部1132に無線通信により送信する。制御部1132は、撮影した放射線画像を記憶部に保存し、最終的には外部端末に転送する。一方、無線通信ではなく有線通信で使用する際には、撮影部10bと制御部1132とは、制御部1132に接続されたケーブル1161を介して優先通信を行う。使用者がケーブル1161の先端のコネクタ1162を撮影部10bのコネクタ1008に接続すると、制御部1132と撮影部10bとが有線通信可能な状態に切替わるとともに、本体バッテリ1131から撮影部10bに電力を供給できる状態となる。
FIG. 16 is a schematic diagram illustrating a configuration example of the radiation imaging apparatus 20b according to the fifth embodiment. The radiation imaging apparatus 20b includes a wireless communication unit 1135 that performs dedicated wireless communication with the communication unit 1007 of the imaging unit 10b. When the input device of the input / output unit 1133 accepts an operation for setting shooting conditions, the control unit 1132 wirelessly transmits a shooting command under the set shooting conditions to the shooting unit 10b via the wireless communication unit 1135. The imaging unit 10b captures a radiographic image in synchronization with the radiation generation unit 1128 in accordance with the received imaging command. Then, the imaging unit 10b transmits the captured radiation image to the control unit 1132 of the radiation imaging apparatus 20b via the communication unit 1007 by wireless communication. The control unit 1132 stores the captured radiographic image in the storage unit, and finally transfers it to the external terminal. On the other hand, when used in wired communication instead of wireless communication, the imaging unit 10 b and the control unit 1132 perform priority communication via the cable 1161 connected to the control unit 1132. When the user connects the connector 1162 at the distal end of the cable 1161 to the connector 1008 of the imaging unit 10b, the control unit 1132 and the imaging unit 10b are switched to a state capable of wired communication, and power is supplied from the main battery 1131 to the imaging unit 10b. Ready to supply.
このように、本実施形態にかかる放射線撮影装置20bは、制御部1132と撮影部10bとの通信部として、有線の通信部と無線の通信部とを有する。そして、制御部1132は、無線通信と有線通信とを切替えるための処理を行う。すなわち、本実施形態においては、本体1121に信号受信部1136が設けられ、信号受信部1136は、外部に設けられたゲート1240,1242,1243,1244の信号発信部1341が発信する無線制限を認識するための信号を受信する。制御部1132は、信号発信部から受信した信号に基づき、無線制限を認識し、無線通信と有線通信とを切替えるための処理、および使用者に切替えを促す処理を実行する。実施形態5では、実施形態4と同様に、図12および図13に示されたゲート1240,1242,1243,1244を使用する。そして、制御部1132は、無線禁止区域A121や、無線禁止区域A121の出入り口近傍において、通信部を切替えるための処理と、使用者に切替えを促す処理を実行する。これにより、使用者は、放射線撮影装置20bが無線禁止区域A121に進入する前に、無線通信から有線通信への切替えを行うことができる。
Thus, the radiation imaging apparatus 20b according to the present embodiment includes a wired communication unit and a wireless communication unit as a communication unit between the control unit 1132 and the imaging unit 10b. Then, the control unit 1132 performs processing for switching between wireless communication and wired communication. That is, in the present embodiment, the main body 1121 is provided with the signal receiving unit 1136, and the signal receiving unit 1136 recognizes the radio restriction transmitted by the signal transmitting unit 1341 of the gates 1240, 1242, 1243, and 1244 provided outside. To receive a signal. The control unit 1132 recognizes the wireless restriction based on the signal received from the signal transmission unit, and executes processing for switching between wireless communication and wired communication, and processing for prompting the user to switch. In the fifth embodiment, similarly to the fourth embodiment, the gates 1240, 1242, 1243, and 1244 shown in FIGS. 12 and 13 are used. And the control part 1132 performs the process for switching a communication part, and the process which prompts a user to switch in radio | wireless prohibition area A121 and the entrance / exit vicinity of radio | wireless prohibition area A121. Thereby, the user can switch from wireless communication to wired communication before the radiation imaging apparatus 20b enters the wireless prohibited area A121.
放射線撮影装置20bを使用する際のワークフローを、図17A、図17Bを参照して説明する。なお、実施形態4と共通するステップには同じ符号を付し、説明を省略する(図14A、図14B参照)。また、フラグ値Feの割り当ても、実施形態4と同じとする。
The workflow when using the radiation imaging apparatus 20b will be described with reference to FIGS. 17A and 17B. In addition, the same code | symbol is attached | subjected to the step which is common in Embodiment 4, and description is abbreviate | omitted (refer FIG. 14A and FIG. 14B). The assignment of the flag value Fe is also the same as in the fourth embodiment.
ステップS1701においては、制御部1132は、撮影部10bと無線通信をしていた場合には、使用者に対して有線通信に切替えるように促す処理を実行する。たとえば、制御部1132は、モニタに、有線通信に切替わっていない旨の表示を行う。または、音声によって、有線通信に切替わっていない旨の報知を行う。
In step S1701, the control unit 1132 executes processing for prompting the user to switch to wired communication when wireless communication is performed with the photographing unit 10b. For example, the control unit 1132 displays on the monitor that the wired communication is not switched. Alternatively, it is notified by voice that it has not been switched to wired communication.
ステップS1702に進んだ場合には、放射線撮影装置20bが切替準備区域A124に進入したため、制御部1132は、無線通信から有線通信に切替えるための処理(切替前処理)を実行する。具体的には、制御部1132は、無線通信部1135により通信している場合には、無線通信の継続時間を推測する。そして、制御部1132は、放射線画像のデータのような情報量の大きいデータを通信している場合には、通信をいったん停止する。追加の撮影オーダー情報のような情報量の少ないデータを通信している場合には、通信を継続する。撮影部10bからの放射線画像のデータの受信である場合には、当該データの受信が完了して記憶部に保存した後、通信を停止する。外部端末への画像のデータの転送である場合には、制御部1132は、転送を中断する旨の信号を当該外部端末に送信するとともに、放射線画像のデータを記憶部に保存する。何らかの障害によって無線通信の状態が低下している場合にも、無線通信を停止する。そして、制御部1132が無線通信の停止を完了すると、ステップS1703に進む。
When the process proceeds to step S1702, since the radiation imaging apparatus 20b has entered the switching preparation area A124, the control unit 1132 executes processing for switching from wireless communication to wired communication (pre-switching processing). Specifically, the control unit 1132 estimates the duration of wireless communication when communication is performed by the wireless communication unit 1135. The control unit 1132 temporarily stops communication when data with a large amount of information such as radiation image data is being communicated. When data with a small amount of information such as additional shooting order information is being communicated, communication is continued. When the radiographic image data is received from the imaging unit 10b, the communication is stopped after the reception of the data is completed and stored in the storage unit. In the case of transferring image data to an external terminal, the control unit 1132 transmits a signal to interrupt the transfer to the external terminal and saves the radiation image data in the storage unit. The wireless communication is also stopped when the state of the wireless communication is lowered due to some trouble. Then, when the control unit 1132 completes the stop of the wireless communication, the process proceeds to step S1703.
ステップS1703においては、制御部1132は、使用者に有線通信への切替えを指示(促す)する処理を実行する。たとえば、制御部1132は、有線通信への切り替えを指示する(促す)メッセージをモニタに表示する。また、音声によって報知してもよい。これにより、放射線撮影装置20bは、使用者により無線通信から有線通信に切替えられるのを待機する切替待機状態に移行する。そして、ステップS1704に進む。なお、ステップS1702の処理が正常に終了しなかった場合には、制御部1132は、その旨をモニタに表示する。切替待機状態に移行すると、使用者は、この指示に従い、その後の撮影オーダーに規定される撮影場所が無線禁止区域A121であるか無線可能区域A122,A123であるかに応じて、切替準備区域A124内において、通信部を無線から有線に切替えることになる。すなわち、作業者は、本体1121から引き出されるケーブル1161のコネクタ1162を、撮影部10bのコネクタ1008に接続する。
In step S1703, the control unit 1132 executes processing for instructing (prompting) the user to switch to wired communication. For example, the control unit 1132 displays a message instructing (prompting) to switch to wired communication on the monitor. Moreover, you may alert | report by an audio | voice. Thereby, the radiation imaging apparatus 20b shifts to a switching standby state in which the user waits for switching from wireless communication to wired communication. Then, the process proceeds to step S1704. If the process in step S1702 has not been completed normally, the control unit 1132 displays that fact on the monitor. When shifting to the switching standby state, the user follows this instruction, and the switching preparation area A124 depends on whether the shooting location specified in the subsequent shooting order is the wireless prohibited area A121 or the wireless available areas A122, A123. The communication unit is switched from wireless to wired. That is, the operator connects the connector 1162 of the cable 1161 drawn from the main body 1121 to the connector 1008 of the imaging unit 10b.
ステップS1704において、制御部1132は、無線通信から有線通信に切替えられたか否かを判定する。たとえば、制御部1132は、ケーブル1161のコネクタ1162が、撮影部10bのコネクタ1008に接続されたか否かを判定する。接続された場合には、無線通信から有線通信に切替えられたと判定し、ステップS1705に進む。そうでない場合には、切替えられていないと判定し、ステップS1704で待機する。ステップS1705において、制御部1132は、撮影部10bとの通信を、ケーブル1161を用いた有線通信に切替える。ステップS1706においては、制御部1132は、通信方式が、現在の区域A121~A124に対して適切に設定されているか否かを判定する。すなわち、制御部1132は、保持しているフラグ値Feが「2」である場合には、ケーブル1161を用いた有線通信であるかを判定する。そして、通信方式が現在の区域A121~A124に対して適切に設定されている場合には、ステップS1413に進む。そうでない場合には、ステップS1404に戻る。
In step S1704, the control unit 1132 determines whether or not the wireless communication is switched to the wired communication. For example, the control unit 1132 determines whether or not the connector 1162 of the cable 1161 is connected to the connector 1008 of the imaging unit 10b. If it is connected, it is determined that the wireless communication is switched to the wired communication, and the process proceeds to step S1705. Otherwise, it is determined that it has not been switched, and waits in step S1704. In step S1705, the control unit 1132 switches communication with the imaging unit 10b to wired communication using the cable 1161. In step S1706, the control unit 1132 determines whether or not the communication method is appropriately set for the current areas A121 to A124. That is, the control unit 1132 determines whether the communication is wired communication using the cable 1161 when the held flag value Fe is “2”. If the communication method is appropriately set for the current areas A121 to A124, the process proceeds to step S1413. Otherwise, the process returns to step S1404.
本実施形態によれば、制御部1132は、無線制限に関する区域の情報を認識し、有線通信と無線通信を切り替える際の確認処理等の前処理を実行する。このため、無線禁止区域A121に進入する場合において、通信中の情報を紛失することなく、無線通信の使用を制限することができる。また、無線通信の使用が制限される区域に進入する場合において、使用者に無線通信の使用の停止を促すことができる。これにより、回診業務の効率の向上を図ることができる。
According to the present embodiment, the control unit 1132 recognizes area information related to wireless restriction, and executes preprocessing such as confirmation processing when switching between wired communication and wireless communication. For this reason, when entering wireless prohibition area A121, use of wireless communication can be restricted without losing information during communication. In addition, when entering an area where the use of wireless communication is restricted, it is possible to prompt the user to stop using the wireless communication. As a result, the efficiency of the round-trip operation can be improved.
<<実施形態6>>
実施形態6は、無線制限の把握を別の態様で行う形態である。撮影部やこの撮影部が適用される放射線撮影装置は、実施形態5と共通である。制御部1132は、オーダー情報を、外部通信部1134を介して院内の外部端末から取得し、制御部1132の記憶部に保存する。そして、制御部1132は、取得したオーダー情報を、操作者が確認できるように、入出力部1133のモニタに、撮影オーダー管理用のワークリストとして表示する。 <<Embodiment 6 >>
Embodiment 6 is a form which grasps | ascertains a radio | wireless restriction in another aspect. The imaging unit and the radiation imaging apparatus to which the imaging unit is applied are the same as those in the fifth embodiment. The control unit 1132 acquires the order information from the external terminal in the hospital via the external communication unit 1134 and stores it in the storage unit of the control unit 1132. Then, the control unit 1132 displays the acquired order information on the monitor of the input / output unit 1133 as a work list for photographing order management so that the operator can confirm it.
実施形態6は、無線制限の把握を別の態様で行う形態である。撮影部やこの撮影部が適用される放射線撮影装置は、実施形態5と共通である。制御部1132は、オーダー情報を、外部通信部1134を介して院内の外部端末から取得し、制御部1132の記憶部に保存する。そして、制御部1132は、取得したオーダー情報を、操作者が確認できるように、入出力部1133のモニタに、撮影オーダー管理用のワークリストとして表示する。 <<
図18は、撮影場所と無線禁止区域A121との対応を管理する情報テーブルを示す図である。図19は、撮影オーダーの管理用のワークリストの表示の例を示す図である。制御部1132は、図18に示すような情報テーブルを有している。たとえば、図18に示す情報テーブルは、A棟の1~3FおよびB棟の3~4Fは無線可能区域として登録され、B棟の1~2Fは無線禁止区域として登録される例を示す。また、使用者は、入出力部1133を介して、この情報テーブルの編集や登録が可能である。すなわち、制御部1132は、入出力部1133への操作に応じて、この情報テーブルの内容を変更する。
FIG. 18 is a diagram showing an information table for managing the correspondence between the shooting location and the wireless prohibited area A121. FIG. 19 is a diagram illustrating a display example of a work list for managing shooting orders. The control unit 1132 has an information table as shown in FIG. For example, the information table shown in FIG. 18 shows an example in which buildings 1 to 3F and buildings 3 to 4F are registered as wireless-enabled areas, and buildings 1 to 2F are registered as wireless prohibited areas. The user can edit and register this information table via the input / output unit 1133. That is, the control unit 1132 changes the contents of this information table in accordance with an operation on the input / output unit 1133.
さらに制御部1132は、撮影オーダーに設定されている撮影場所と前記情報テーブルとから、各撮影オーダーで使用すべき通信部と場所情報とを関連付ける。たとえば、制御部1132は、図18に示すように、「A棟の2Fは無線可能エリアに登録されていれば、撮影オーダーにおけるA205病室での撮影は無線通信可能である」というように、適切な通信部と場所情報とを関連付けする。そして、制御部1132は、図19に示すように、モニタに表示したリストに、A205病室は無線可能区域A122,A123であることを、たとえばアイコンを用いて示す。また、ICU01は無線禁止区域A121であることを有線のアイコンで示す。
Further, the control unit 1132 associates the communication unit to be used in each shooting order with the location information from the shooting location set in the shooting order and the information table. For example, as shown in FIG. 18, the control unit 1132 may appropriately select “if the 2F of the A building is registered in the wireless area, the imaging in the A205 room in the imaging order can be wirelessly communicated”. The communication unit and the location information are associated with each other. Then, as shown in FIG. 19, the control unit 1132 indicates, for example, using an icon in the list displayed on the monitor that the A205 hospital room is a wirelessly available area A122, A123. Further, ICU01 indicates that it is a wireless prohibited area A121 with a wired icon.
そして、各撮影オーダーに設定された通信部に対して現在の通信部が適切かどうかを使用者が認識できるように、制御部1132は、撮影オーダーや設定されている通信部の表示態様を変更する。変更する表示態様の例としては、表示のカラーやコントラストが挙げられる。たとえば、制御部1132は、撮影オーダーに対して現在使用中の通信部が適切である場合には緑色で表示し、そうでない場合には赤色で表示する。また、制御部1132は、撮影オーダーに対して現在使用中の通信部が適切である場合には表示のコントラストを下げる。
Then, the control unit 1132 changes the shooting order and the display mode of the set communication unit so that the user can recognize whether the current communication unit is appropriate for the communication unit set for each shooting order. To do. Examples of the display mode to be changed include display color and contrast. For example, the control unit 1132 displays in green when the communication unit currently in use for the photographing order is appropriate, and displays in red otherwise. In addition, the control unit 1132 reduces the display contrast when the communication unit currently in use is appropriate for the imaging order.
また、次のような構成であってもよい。すなわち、制御部1132は、使用者によって次に実行する撮影オーダーがリスト上から選択されると、次に実行する撮影オーダーに対して現在の通信部が適切か否かを判定する。そして、適切でない場合は、制御部1132は、切替えを促すようなメッセージを、モニタに表示したり音声で発したりする。このような構成によれば、使用者は、各撮影オーダーに対して通信部が適切かどうかを確認しやすくなる。したがって、使用者は、撮影オーダーに応じた通信方式を選択できるようになる。さらに、制御部1132は、撮影オーダー管理用のワークリストの各撮影オーダーを、設定されている通信部(すなわち、適切な通信部)に応じてソートしてもよい。たとえば、制御部1132は、無線可能区域A122,A123に存在する撮影場所をソートして抽出する。これにより使用者は、効率的な回診のルート検討が可能となる。以上のとおり、実施形態5によれば、実施形態4と同様の効果を奏することができる。
Also, the following configuration may be used. That is, when the next shooting order to be executed is selected from the list by the user, the control unit 1132 determines whether or not the current communication unit is appropriate for the next shooting order to be executed. If not appropriate, the control unit 1132 displays a message for prompting switching on the monitor or emits a voice. According to such a configuration, the user can easily confirm whether or not the communication unit is appropriate for each photographing order. Therefore, the user can select a communication method according to the photographing order. Furthermore, the control unit 1132 may sort each shooting order in the work list for shooting order management according to a set communication unit (that is, an appropriate communication unit). For example, the control unit 1132 sorts and extracts the shooting locations existing in the wireless coverage areas A122 and A123. This allows the user to study the route for an efficient round trip. As described above, according to the fifth embodiment, the same effects as those of the fourth embodiment can be obtained.
前述の各実施形態では、ゲート1240,1242,1243,1244に設けられた信号発信部1341から無線制限を認識するための信号を受信することによって、区域A121~A124を認識する構成例を説明した。ここでは、区域A121~A124の新指揮するための他の構成について簡単に説明する。なお、前述の各実施形態と共通の構成については説明を省略する。
In each of the above-described embodiments, the configuration example has been described in which the areas A121 to A124 are recognized by receiving a signal for recognizing the wireless restriction from the signal transmission unit 1341 provided in the gates 1240, 1242, 1243, and 1244. . Here, a brief description will be given of another configuration for newly conducting the areas A121 to A124. In addition, description is abbreviate | omitted about the structure common to each above-mentioned embodiment.
放射線撮影装置20a,20bの本体1121には、現在位置を把握するための現在位置認識部が設けられる。現在位置認識部は、車輪1124の回転を検出する回転検出部1125と、移動方向を検出する検出部と、重力方向へ移動を検出する検出部と、院内のマップを有する。マップには、各区域A121~A124の位置情報が含まれている。そして、現在位置認識部は、これらの各検出部からの情報をもとに、相対的な位置変化や移動量を計算して現在地を認識し、マップを参照して現在地が区域A121~A124のいずれに位置しているかを認識する。認識結果は、制御部1132に逐次送信される。これにより、制御部1132は、放射線撮影装置20a,20bが現在いずれの区域A121~A124に存在するかや、各区域A121~A124との接近の程度を認識できる。なお、前述のマップは、院内のフロアごとに作成されて保持されている。また、入出力部1133のモニタ(表示部)は、このマップをフロアごとに切替えて表示できる。さらに、放射線撮影装置20a,20bは、使用者による入出力部1133の操作にしたがってマップを編集する機能(各区域A121~A124を設定する)を有していてもよい。
The main body 1121 of the radiation imaging apparatuses 20a and 20b is provided with a current position recognition unit for grasping the current position. The current position recognition unit includes a rotation detection unit 1125 that detects the rotation of the wheel 1124, a detection unit that detects a movement direction, a detection unit that detects movement in the direction of gravity, and an in-hospital map. The map includes position information for each of the areas A121 to A124. The current position recognition unit recognizes the current location by calculating a relative position change and movement amount based on the information from each of these detection units, and refers to the map to determine the current location in the areas A121 to A124. Recognize where it is located. The recognition result is sequentially transmitted to the control unit 1132. Thereby, the control unit 1132 can recognize in which area A121 to A124 the radiation imaging apparatuses 20a and 20b are present and the degree of approach to each area A121 to A124. The aforementioned map is created and held for each floor in the hospital. The monitor (display unit) of the input / output unit 1133 can switch and display this map for each floor. Furthermore, the radiation imaging apparatuses 20a and 20b may have a function of editing a map (setting each area A121 to A124) in accordance with an operation of the input / output unit 1133 by the user.
また、放射線撮影装置20a,20bの現在位置認識部は、前述のような自律航法型の各検出部に加え、GPSなどの外部から受信した電波を利用する測位部を有していてもよい。そしてこの場合には、現在位置認識部は、放射線撮影装置20a,20bが無線禁止区域A121に進入した場合には、自立航法型の各検出部を用いて現在位置を認識する。一方、無線禁止区域A121以外の区域に存在する場合には、電波を利用した測位部を用いて現在位置を認識する。このような構成によれば、無線禁止区域A121における無線通信の制限と、現在地の正確な把握とを両立することが可能となる。
Further, the current position recognition unit of the radiation imaging apparatuses 20a and 20b may include a positioning unit that uses radio waves received from the outside such as GPS, in addition to the above-described autonomous navigation type detection units. In this case, the current position recognizing unit recognizes the current position using each of the self-contained navigation type detection units when the radiation imaging apparatuses 20a and 20b enter the wireless prohibited area A121. On the other hand, when it exists in areas other than the wireless prohibition area A121, the current position is recognized using a positioning unit using radio waves. According to such a configuration, it is possible to achieve both the restriction of wireless communication in the wireless prohibited area A121 and the accurate grasp of the current location.

In this case, in the description of each embodiment described above, “a control unit provided in the main body of the radiation imaging apparatus” may be replaced with “a control unit provided in the input / output unit”. As the input / output unit 1133 that is separate from the main body 1121, a portable electronic computer (computer) such as a notebook PC can be used. In this case, the portable computer and the program stored in the recording medium in the computer cooperate to function as the control unit 1132 or the control device. Furthermore, the radiation generation unit 1128 may include a control unit and a signal reception unit, and the control unit may execute the processes shown in the above-described embodiments.

For example, any of the input / output unit, the imaging unit, and the radiation generation unit may include a control unit and a wireless communication unit, and the control unit may execute the above-described processing. These are also included in the technical scope of the present invention.
別の実施形態では、各装置間の通信経路の一部に無線が用いられる。放射線撮影装置は、制御装置としての可搬型の電子計算機と、電子計算機に有線接続された通信の中継器(通信中継器)とを有する。通信の中継器はいわゆるアクセスポイントであり、撮影部10bとの間、あるいは撮影管理システムとの間で無線通信(無線接続)を行う。この場合撮影管理システムが接続する別の無線中継器との間で無線通信を行い、当該別の無線中継器と撮影管理システムの間は有線通信する。かかる実施形態では、制御装置が中継器を制御し、無線禁止器区域に所定距離近づいた場合に、種々の前処理の後に中継器による無線通信を行わないよう制御する。あるいは、中継器を介して撮影部10bが無線通信している場合に、制御装置は撮影部10bの無線通信を停止させる信号を送信した後に、中継器の無線通信を停止させる信号を送信させることとすれば、撮影部10bが接続確立の試行処理を繰り返すという無駄をなくすことができる。
In another embodiment, wireless is used as part of the communication path between the devices. The radiation imaging apparatus includes a portable electronic computer as a control device, and a communication repeater (communication repeater) wired to the electronic computer. The communication repeater is a so-called access point, and performs wireless communication (wireless connection) with the photographing unit 10b or with the photographing management system. In this case, wireless communication is performed with another wireless repeater to which the photographing management system is connected, and wired communication is performed between the other wireless repeater and the photographing management system. In such an embodiment, when the control device controls the repeater and approaches the wireless prohibitor zone by a predetermined distance, control is performed so that wireless communication by the repeater is not performed after various preprocessing. Or when the imaging | photography part 10b is communicating wirelessly via a repeater, after transmitting the signal which stops the wireless communication of the imaging | photography part 10b, a control apparatus transmits the signal which stops the wireless communication of a repeater If this is the case, it is possible to eliminate the waste of the imaging unit 10b repeating the connection establishment trial process.
また別の実施形態では、撮影部10b(放射線検出器)側にGPS及びMPU等からなる位置認識回路を設け、MPUが位置認識回路から無線の使用が制限される無線禁止区域に所定距離に近づいたと認識した場合には、無線通信制限に対応するための処理を実行し、処理が完了した後、撮影部10bの通信部1007による無線通信を制限する制御を行うこととする。このようにすることで、例えば撮影部10bと別体の制御装置がない場合であっても、無線通信制限を実行することができる。
In another embodiment, a position recognition circuit including a GPS and an MPU is provided on the imaging unit 10b (radiation detector) side, and the MPU approaches a radio prohibited area where use of radio is restricted from the position recognition circuit to a predetermined distance. If it is recognized that the communication unit 1007 recognizes that the wireless communication is restricted, control for restricting wireless communication by the communication unit 1007 of the imaging unit 10b is performed after the processing is completed. By doing in this way, for example, even when there is no control device separate from the photographing unit 10b, it is possible to execute wireless communication restriction.

また本体部2121には放射線撮影部2010を収納するための収納部2130が設けられており、移動時には放射線撮影部2010を収納することができる。放射線撮影部2010は使用時に収納部2130から取り出されて使用される。なお収納部2130は本体部2121と一体として形成されてもよく、本体部2121とは別に形成されてもよい。また本体部2121は、バッテリ2131と、制御部2132と、入出力部2133と、外部通信部2134と、無線通信部2135と、受信部2136とを備えている。
Further, the main body 2121 is provided with a storage unit 2130 for storing the radiation imaging unit 2010, and the radiation imaging unit 2010 can be stored when moving. The radiation imaging unit 2010 is taken out from the storage unit 2130 when used. Note that the storage portion 2130 may be formed integrally with the main body portion 2121, or may be formed separately from the main body portion 2121. The main body unit 2121 includes a battery 2131, a control unit 2132, an input / output unit 2133, an external communication unit 2134, a wireless communication unit 2135, and a reception unit 2136.

入出力部2133は、表示出力のためのモニタと、操作者からの入力を受け付けるための操作受付部とを備えており、放射線撮影装置2120の操作のために使用される。本実施形態では、本体部2121の上部に配置されている。操作受付部は、例えば、モニタ上の選択位置を切替えるための物理ボタンや、タッチパネル等で構成してもよい。
The input / output unit 2133 includes a monitor for display output and an operation reception unit for receiving input from the operator, and is used for operation of the radiation imaging apparatus 2120. In the present embodiment, it is arranged at the upper part of the main body 2121.

Such information is transmitted / received to / from an external device in the hospital via an external communication unit 2134 connected to the control unit 2132.
撮影する際には、放射線撮影部2010に内蔵された無線通信部2007と専用に通信する無線通信部2135が用いられる。制御部2132は、入出力部2133により設定された条件での撮影指令を放射線撮影部2010へ送信する。放射線撮影部2010からは、放射線発生部2128と同期して撮影された放射線画像が送信されてくる。撮影された放射線画像は、制御部2132内の画像記録部に保存され、最終的に外部機器に転送される。

The receiving unit 2136 receives predetermined information for recognizing wireless communication restrictions. The control unit 2132 recognizes the restriction of wireless communication based on information transmitted from a transmitter provided outside, and restricts wireless communication by the external communication unit 2134 and the wireless communication unit 2135.
本実施形態では、図22に示すように施設壁面等に設けられた発信装置2240に、所定の信号を発信する発信部2241が設けられている。発信部2241と受信部2136との組合せにより、発信装置2240に対する放射線撮影装置2120の近接度を判定することができる。発信装置2240に最も近接した時が、放射線撮影装置2120が発信装置2240の付近を通過した時であると認識できる。発信部2241から発信される所定の信号の受信強度を判定し、最も強い強度になったときに最も近接したと判定すればよい。
In this embodiment, as shown in FIG. 22, a transmitting unit 2241 that transmits a predetermined signal is provided in a transmitting device 2240 provided on a facility wall surface or the like. The proximity of the radiation imaging apparatus 2120 to the transmission apparatus 2240 can be determined by a combination of the transmission section 2241 and the reception section 2136. It can be recognized that the time closest to the transmission device 2240 is the time when the radiation imaging apparatus 2120 has passed near the transmission device 2240. The reception intensity of a predetermined signal transmitted from the transmission unit 2241 may be determined, and it may be determined that the signal is closest when the strongest intensity is obtained.
あるいは、受信強度が予め設定された閾値を超えた場合に最も近接したと判定するようにしてもよい。あるいは受信強度に応じて、無線通信が制限される区域から所定距離範囲内に放射線撮影装置2120が近接したことを検知してもよい。当該検知に応じて、無線通信が制限されている区域へ移動する前に、予め外部機器に対して撮影済の画像データの転送や、新たな撮影オーダーの有無の確認を行ってもよい。
Alternatively, it may be determined that the reception is closest when the reception intensity exceeds a preset threshold. Alternatively, it may be detected that the radiation imaging apparatus 2120 has approached within a predetermined distance from an area where wireless communication is restricted, according to the reception intensity. In response to the detection, before moving to an area where wireless communication is restricted, image data that has already been captured may be transferred to an external device, or whether or not there is a new imaging order may be confirmed.
例えば、図23に示すようなレイアウトの院内のフロアにおいて、区域A231は無線通信の影響を受けやすい機器を設置しているスペースであり無線制限をすべき区域であるものとする。一方、入院患者の病室は区域A232、区域A233であり、ここでは回診撮影のために無線通信が必要になる。区域A234は、区域A231、区域A232、区域A233の間を行き来するための通過区域である。区域A234は、無線通信制限の切替準備のための区域である。発信装置2240を区域A232の入口付近に、発信装置2342を区域A231の入口付近に、発信装置2344を区域A233の入口付近にそれぞれ配置する。また発信装置2343をエレベータ出入口の付近に配置している。各発信装置2240、2342、2343、2344は、発信部2241をそれぞれ有しており、所定の情報を発信している。放射線撮影装置2120は、各発信装置から発信される情報を受信し、自身の現在位置と各発信装置との相対的な近接度を認識することができる。
For example, in the hospital floor with the layout as shown in FIG. 23, it is assumed that the area A231 is a space in which devices that are easily affected by wireless communication are installed and should be restricted. On the other hand, hospital rooms of hospitalized patients are area A232 and area A233, and wireless communication is required for round-trip imaging here. The area A234 is a passing area for moving between the area A231, the area A232, and the area A233. Area A234 is an area for preparing for switching of wireless communication restriction. The transmitting device 2240 is disposed near the entrance of the area A232, the transmitting device 2342 is disposed near the entrance of the area A231, and the transmitting device 2344 is disposed near the entrance of the area A233. A transmitter 2343 is arranged in the vicinity of the elevator doorway. Each transmission device 2240, 2342, 2343, 2344 has a transmission unit 2241 and transmits predetermined information. The radiation imaging apparatus 2120 can receive information transmitted from each transmitting apparatus and recognize the relative proximity between its current position and each transmitting apparatus.
以下、図24A、図24Bのフローチャートを参照して、実施形態7に係る放射線撮影装置2120が実施する処理の動作手順について説明する。ステップS2400において、制御部2132は、準備状態として、ACケーブル(不図示)を介して接続された商用電源によりバッテリ2131を充電する。ステップS2401において、制御部2132は、外部通信部2134を介して院内のRIS(Radiology Information System)端末等の外部機器からオーダー情報を取得する。
Hereinafter, an operation procedure of processing performed by the radiation imaging apparatus 2120 according to the seventh embodiment will be described with reference to flowcharts of FIGS. 24A and 24B. In step S2400, the control unit 2132 charges the battery 2131 with a commercial power source connected via an AC cable (not shown) as a preparation state. In step S2401, the control unit 2132 acquires order information from an external device such as a hospital RIS (Radiology Information System) terminal via the external communication unit 2134.
ステップS2402において、入出力部2133は、取得されたオーダー情報を表示する。表示されるオーダー情報は、患者氏名、性別などの患者情報や病室番号、撮影部位や撮影姿勢等の撮影要件などである。操作者は、表示されたオーダー情報を確認し、院内回診の優先度や移動ルートを考慮して回診撮影の大まかなスケジュールを計画する。ステップS2403において、制御部2132は、商用電源からのACケーブルの取り外しを検知する。
In step S2402, the input / output unit 2133 displays the acquired order information. The displayed order information includes patient information such as a patient name and sex, a room number, imaging requirements such as an imaging region and an imaging posture, and the like. The operator confirms the displayed order information and plans a rough schedule for the round trip taking into consideration the priority of the hospital round and the travel route. In step S2403, the control unit 2132 detects the removal of the AC cable from the commercial power source.
ステップS2404において、制御部2132は、操作者が放射線撮影装置2120を押しながら計画されたスケジュールに沿って所定の病室へ移動を開始したことを検知する。ここで制御部2132は、区域の無線通信の制限レベルを管理するためのフラグ値Feを管理している。区域の種類には、たとえば無線可能区域、無線切替準備区域、無線制限区域があり、フラグ値として、各々0、1、2が割り当てられている。各発信装置は、各々が配置された区域に対応したフラグ値を所定の信号に含めて発信している。ここで無線可能区域とは、無線通信を制限なく実施可能な区域である。無線制限区域とは、無線通信により当該区域に配置された機器に影響を及ぼす可能性があるため、無線通信自体を制限する区域である。無線切替準備区域とは、無線可能区域及び無線制限区域以外の区域であり、無線制限区域への進入に備えて無線通信が制限される前に必要な切替準備を実施する区域である。フラグ値Feは無線通信の可否を判定するための情報として使用することができる。
In step S2404, the control unit 2132 detects that the operator has started moving to a predetermined room along the planned schedule while pressing the radiation imaging apparatus 2120. Here, the control unit 2132 manages a flag value Fe for managing the restriction level of radio communication in the area. The types of areas include, for example, a radio-enabled area, a radio switching preparation area, and a radio restricted area, and 0, 1, and 2 are assigned as flag values, respectively. Each transmitting device transmits a flag value corresponding to the area in which each transmitting device is included in a predetermined signal. Here, the wireless area is an area where wireless communication can be performed without restriction. The wireless restricted area is an area that restricts wireless communication itself because there is a possibility of affecting a device arranged in the area by wireless communication. The radio switching preparation area is an area other than the radio-enabled area and the radio restricted area, and is an area in which necessary switching preparation is performed before radio communication is restricted in preparation for entering the radio restricted area. The flag value Fe can be used as information for determining whether or not wireless communication is possible.
ステップS2405において、制御部2132は、発信装置から受信する所定の情報に基づいて、放射線撮影装置2120が発信装置を通過したことを検知する。通過検知については、発信装置から受信される所定の信号の受信強度に基づいて判定すればよい。発信装置の通過を検知した場合、ステップS2406へ進む。一方、発信装置の通過を検知していない場合、ステップS2407へ進む。
In step S2405, the control unit 2132 detects that the radiation imaging apparatus 2120 has passed through the transmission apparatus based on predetermined information received from the transmission apparatus. The passage detection may be determined based on the reception intensity of a predetermined signal received from the transmission device. If the passage of the transmission device is detected, the process proceeds to step S2406. On the other hand, if the passage of the transmission device is not detected, the process proceeds to step S2407.
ステップS2406において、制御部2132は、発信装置の発信部から発信されている所定の情報を受信して、当該情報に含まれるフラグ値のデータに基づいて制御部2132が保持しているフラグ値Feを変更する。その後、ステップS2407へ進む。
In step S2406, the control unit 2132 receives predetermined information transmitted from the transmission unit of the transmission device, and the flag value Fe held by the control unit 2132 based on the flag value data included in the information. To change. Thereafter, the process proceeds to step S2407.
ステップS2407において、制御部2132は、フラグ値Fe=2であるか否か判定する。すなわち、放射線撮影装置2120の移動先の区域が無線制限区域であるか否かを判定する。フラグ値Fe=2である場合、ステップS2408へ進む。一方、フラグ値Fe=2でない場合(Fe=0または1である場合)、ステップS2410へ進む。
In step S2407, the control unit 2132 determines whether or not the flag value Fe = 2. That is, it is determined whether or not the area to which the radiation imaging apparatus 2120 is moved is a wireless restricted area. If the flag value Fe = 2, the process proceeds to step S2408. On the other hand, when the flag value is not Fe = 2 (when Fe = 0 or 1), the process proceeds to step S2410.
例えば、図23に示すように、エレベータ出入口には発信装置2343が配置されている。発信装置2343の発信部は、フラグ値Fe=1への切替境界であることを報知している。操作者が放射線撮影装置2120を移動してエレベータを下り、発信装置2343を通過することによりフラグ値Feが1に変更されることになる。また発信装置2240、44の発信部は、フラグ値Fe=0への切替境界であることを報知し、発信装置2342の発信部はフラグ値Fe=2への切替境界であることを報知している。
For example, as shown in FIG. 23, a transmitter 2343 is arranged at the elevator entrance. The transmission unit of the transmission device 2343 notifies that it is a switching boundary to the flag value Fe = 1. The flag value Fe is changed to 1 when the operator moves the radiation imaging apparatus 2120 to descend the elevator and passes the transmission apparatus 2343. Further, the transmission unit of the transmission devices 2240 and 44 notifies that it is a switching boundary to the flag value Fe = 0, and the transmission unit of the transmission device 2342 notifies that it is the switching boundary to the flag value Fe = 2. Yes.
ステップS2408において、制御部2132は、無線通信を制限する。ステップS2409において、制御部2132は、無線通信の制御を切り替えたことを操作者へ報知する。ステップS2410において、制御部2132は、無線通信制御を解除する。
In step S2408, the control unit 2132 restricts wireless communication. In step S2409, the control unit 2132 notifies the operator that the wireless communication control has been switched. In step S2410, the control unit 2132 releases the wireless communication control.
ステップS2411において、制御部2132は、フラグ値Fe=0であるか否か判定する。すなわち、放射線撮影装置2120の移動先の区域が無線可能区域であるか否かを判定する。フラグ値Fe=0である場合、ステップS2412へ進む。一方、フラグ値Fe=0でない場合(Fe=1である場合、すなわち無線切替準備区域である場合)、ステップS2415へ進む。
In step S2411, the control unit 2132 determines whether or not the flag value Fe = 0. That is, it is determined whether or not the area to which the radiation imaging apparatus 2120 is moved is a wireless area. If the flag value Fe = 0, the process proceeds to step S2412. On the other hand, when the flag value is not Fe = 0 (when Fe = 1, that is, when it is a radio switching preparation area), the process proceeds to step S2415.
ステップS2412において、制御部2132は、区域A232、区域A233等の所定の病室に到着して放射線撮影装置2120の移動が停止したことを検知する。操作者は、放射線発生部2128を所定の撮影姿勢に対して位置調整して、入出力部2133のモニタ上で撮影部位を選択し、放射線発生部2128の管電圧や、管電流(mA)と時間(sec)の積であるmAs値等の撮影条件を設定する。準備が完了すると撮影が実行される。
In step S2412, the control unit 2132 detects that the movement of the radiation imaging apparatus 2120 has stopped by arriving at a predetermined hospital room such as the section A232 or the section A233. The operator adjusts the position of the radiation generation unit 2128 with respect to a predetermined imaging posture, selects an imaging region on the monitor of the input / output unit 2133, and sets the tube voltage and tube current (mA) of the radiation generation unit 2128. An imaging condition such as a mAs value that is a product of time (sec) is set. When preparation is completed, shooting is performed.
ステップS2413において、制御部2132は、撮影が終了すると撮影済であることを管理情報に反映し、リストを更新する。また撮影終了に伴い、放射線撮影部2010は操作者により収納部2130に戻される。
In step S2413, when the shooting is completed, the control unit 2132 reflects in the management information that the shooting has been completed, and updates the list. In addition, with the completion of imaging, the radiation imaging unit 2010 is returned to the storage unit 2130 by the operator.
ステップS2414において、操作者は撮影オーダーをチェックし、オーダーが残っている場合は、ステップS2405に戻る。そして次の病室等へ移動し、一連のフローを繰り返す。一方、撮影オーダーが残っていない場合、ステップS2417へ進む。
In step S2414, the operator checks the shooting order. If the order remains, the process returns to step S2405. And it moves to the next hospital room etc. and repeats a series of flows. On the other hand, if no shooting order remains, the process advances to step S2417.
ステップS2415において、制御部2132は、無線通信の制限に備えた前処理を実行する。これは、放射線撮影装置2120がFe=1の無線切替準備区域(図23では区域A234)、すなわち無線制限区域(図23では区域A231)に隣接した区域に移動することから、区域A231へ侵入する可能性を予め想定しておき、将来の無線制限に備えるものである。具体的には、制御部2132は、外部の管理システムに対して自動的に、緊急の撮影オーダーの有無の問い合わせ、新規のオーダーの取得、撮影済の画像データの転送、画像転送の優先案件の確認等の前処理を行う。
In step S2415, the control unit 2132 executes pre-processing for limiting wireless communication. This is because the radiation imaging apparatus 2120 moves to the radio switching preparation area (area A 234 in FIG. 23), that is, an area adjacent to the radio restricted area (area A 231 in FIG. 23), and enters the area A 231. The possibility is assumed in advance to prepare for future radio restrictions. Specifically, the control unit 2132 automatically inquires of an external management system whether there is an urgent photographing order, obtains a new order, transfers photographed image data, and sets an image transfer priority item. Perform pre-processing such as confirmation.
ステップS2416において、制御部2132は、S2415の処理が終了すると、入出力部2133のモニタに前処理が完了した旨のメッセージを表示したり、音声による報知を行ったりする。また、放射線撮影装置2120が無線制限区域に近づいている旨のメッセージを表示もしくは音声で報知してもよい。操作者はこのメッセージを受けて、移動を継続するか否かを選択してもよい。
In step S2416, when the processing of S2415 is completed, the control unit 2132 displays a message indicating that the preprocessing is completed on the monitor of the input / output unit 2133, or performs a voice notification. Further, a message indicating that the radiation imaging apparatus 2120 is approaching the wireless restricted area may be displayed or voiced. Upon receiving this message, the operator may select whether or not to continue the movement.
なお、ステップS2415において、制御部2132は、放射線撮影部2010の無線通信部2007から放射線撮影部2010の状態に関する情報をさらに収集してもよい。状態に関する情報としては、バッテリ状態、センサの駆動状態、内部温度の情報のいずれかを含んでもよい。そしてステップS2416において、制御部2132は、状態に関する情報に基づいて、撮影の障害になるような情報の有無について確認を行い、必要なら所定の処置を促すようなメッセージを表示もしくは報知してもよい。
In step S2415, the control unit 2132 may further collect information regarding the state of the radiation imaging unit 2010 from the wireless communication unit 2007 of the radiation imaging unit 2010. Information on the state may include any of battery state, sensor driving state, and internal temperature information. In step S2416, the control unit 2132 may check whether there is information that may cause a shooting failure based on information about the state, and display or notify a message that prompts a predetermined treatment if necessary. .
なお制御部2132は、放射線撮影装置2120が発信装置2342を通過し、無線制限区域(区域A231)から無線切替準備区域(区域A234)へ退出した場合、無線制限を解除し、オーダー情報や放射線撮影部2010の状態に関する情報を確認する処理を行い、状況に変化があった場合はメッセージを表示もしくは報知する。たとえば、上述の通過検知に加えて、放射線撮影装置2120が現在保持しているフラグ値がFe=2であり、他の発信装置から新たに受信した情報に含まれるフラグ値データがFe=1である場合、無線制限区域(区域A231)から無線切替準備区域(区域A234)へ退出したと判定できる。
The control unit 2132 cancels the wireless restriction when the radiation imaging apparatus 2120 passes through the transmission apparatus 2342 and exits from the wireless restricted area (area A231) to the wireless switching preparation area (area A234), and the order information or the radiographic imaging is released. Processing for confirming information related to the state of the unit 2010 is performed, and when there is a change in the situation, a message is displayed or notified. For example, in addition to the above-described passage detection, the flag value currently held by the radiation imaging apparatus 2120 is Fe = 2, and the flag value data included in the information newly received from another transmitting apparatus is Fe = 1. In some cases, it can be determined that the user has left the wireless restricted area (area A231) to the wireless switching preparation area (area A234).
ステップS2417において、制御部2132は、放射線撮影装置2120が所定の待機基地に到着して返却されたか否かを判定する。返却されたと判定された場合、ステップS2418へ進む。一方、返却されていないと判定された場合、ステップS2405に戻る。
In step S2417, the control unit 2132 determines whether or not the radiation imaging apparatus 2120 has arrived at the predetermined standby base and returned. If it is determined that it has been returned, the process proceeds to step S2418. On the other hand, if it is determined that it has not been returned, the process returns to step S2405.
ステップS2418において、制御部2132は、RISに撮影オーダーの処理結果を出力して、回診撮影を終了する。
In step S2418, the control unit 2132 outputs the imaging order processing result to the RIS, and ends the round imaging.
以上説明したように、本実施形態では、無線制限に関する区域の情報に基づいて無線制限を実施するとともに、無線制限を行う前に確認処理等の処理を予め実行しておくことで、安全かつ効率よく回診業務を実行することができる。本実施形態によれば、無線制限に関する情報を事前にユーザに提供し、不適切な無線通信の発生を低減させることが可能となる。
As described above, in the present embodiment, the radio restriction is performed based on the area information related to the radio restriction, and the process such as the confirmation process is performed in advance before performing the radio restriction. Can often perform round trips. According to the present embodiment, it is possible to provide information related to the wireless restriction to the user in advance and reduce the occurrence of inappropriate wireless communication.

Embodiment 8 will be described with reference to FIGS. 25 to 27A and 27B. In the present embodiment, an example will be described in which not only wireless communication but also wired communication is possible between the radiation imaging apparatus main body and the radiation imaging unit, and wireless or wired switching is possible. Note that the same reference numerals as those in the seventh embodiment are used for common elements constituting the radiation imaging apparatus and the radiation imaging unit.
図25乃至図27A、図27Bを参照して、実施形態8について説明する。本実施形態では、放射線撮影装置本体と放射線撮影部との間で無線通信だけではなく有線通信も可能であり、無線または有線を切替可能な例を説明する。なお、放射線撮影装置や放射線撮影部を構成する共通の要素に関しては、実施形態7と同じ参照符号を用いている。 <<
図25は、本実施形態に係る放射線撮影装置が有する放射線撮影部2050の側面断面図であり、図26は、本実施形態に係る移動型の放射線撮影装置2060の構成例を説明するための図である。
FIG. 25 is a side cross-sectional view of the radiation imaging unit 2050 included in the radiation imaging apparatus according to the present embodiment, and FIG. 26 is a diagram for describing a configuration example of the mobile radiation imaging apparatus 2060 according to the present embodiment. It is.
図25に示すように、放射線撮影部2050は、画像信号や制御信号などの信号伝送を担う通信部2009を備えている。無線状態で使用する際は、バッテリ2006による回路基板2003等への給電と、通信部2009に内蔵された無線通信機能による通信が行われる。一方、無線ではなく有線ケーブルが使用される場合は、筐体本体2005aの外装に形成されたコネクタ2008に対して外部から有線ケーブルを接続する。有線ケーブルを介して直接給電と通信を行うため、電池切れや無線による通信の不安定さは解消される。
As shown in FIG. 25, the radiation imaging unit 2050 includes a communication unit 2009 that is responsible for signal transmission such as image signals and control signals. When used in a wireless state, power is supplied to the circuit board 2003 and the like by the battery 2006, and communication is performed using a wireless communication function built in the communication unit 2009. On the other hand, when a wired cable is used instead of wireless, the wired cable is connected from the outside to a connector 2008 formed on the exterior of the housing body 2005a. Since power supply and communication are performed directly via a wired cable, battery instability and wireless communication instability are eliminated.
図26に示すように、放射線撮影装置2060と組み合わせて撮影を行う際には、放射線撮影部2050に内蔵された通信部2009と専用に通信する無線通信部2135が用いられる。一方、放射線撮影部2050を無線ではなく、有線で使用する場合には、制御部2132に接続されたケーブル2161を使用する。ケーブル2161の先端のコネクタ2162を放射線撮影部2050のコネクタ2008に接続することで、電力供給と通信を有線で行うことができる。
As shown in FIG. 26, when imaging is performed in combination with the radiation imaging apparatus 2060, a wireless communication unit 2135 that communicates exclusively with the communication unit 2009 built in the radiation imaging unit 2050 is used. On the other hand, when the radiation imaging unit 2050 is used not by radio but by wire, a cable 2161 connected to the control unit 2132 is used. By connecting the connector 2162 at the end of the cable 2161 to the connector 2008 of the radiation imaging unit 2050, power supply and communication can be performed by wire.
放射線撮影装置2060の制御部2132は、実施形態7で説明したような発信装置の発信部から発信される切替信号を受信して、有線/無線を切り替える。放射線撮影装置2060が無線制限区域に入る前に、有線/無線の切替えを行い、無線制限区域では有線を使用するように制御する。
The control unit 2132 of the radiation imaging apparatus 2060 receives the switching signal transmitted from the transmission unit of the transmission apparatus as described in the seventh embodiment, and switches between wired / wireless. Before the radiation imaging apparatus 2060 enters the wireless restricted area, wired / wireless switching is performed, and control is performed so that wired is used in the wireless restricted area.
以下、図27A、図27Bのフローチャートを参照して、実施形態8に係る放射線撮影装置2060が実施する処理の手順について説明する。制御部2132は、区域の無線通信の制限レベルを管理するためのフラグ値Feを管理している。本実施形態に係る区域の種類には、たとえば無線可能区域、無線/有線切替区域、有線区域(無線制限区域)があり、フラグ値として、各々0、1、2が割り当てられている。各発信装置は、実施形態7と同様に各々が配置された区域に対応したフラグ値を発信している。
Hereinafter, the procedure of processing performed by the radiation imaging apparatus 2060 according to the eighth embodiment will be described with reference to the flowcharts of FIGS. 27A and 27B. The control unit 2132 manages a flag value Fe for managing the restriction level of radio communication in the area. The types of areas according to the present embodiment include, for example, a wireless area, a wireless / wired switching area, and a wired area (wireless restriction area), and 0, 1, and 2 are assigned as flag values, respectively. Each transmitter transmits a flag value corresponding to the area in which each transmitter is disposed, as in the seventh embodiment.
ステップS2700-S2708、S2710、S2713-S2715、S2719-S2720の各処理は、ステップS2400-S2408、S2410、S2412-S2414、S2417-S2418の各処理と同様であるため説明を省略する。
Steps S2700-S2708, S2710, S2713-S2715, and S2719-S2720 are the same as steps S2400-S2408, S2410, S2412-S2414, and S2417-S2418, and thus description thereof is omitted.
ステップS2709において、制御部2132は、S2708で無線通信が制限された後、操作者に対して、無線制限がなされたこと、有線への切替がまだなされていないことを報知する。これにより操作者に有線への切替を促す。
In step S2709, after the wireless communication is restricted in step S2708, the control unit 2132 notifies the operator that the wireless restriction has been made and that the switch to wired has not yet been made. This prompts the operator to switch to wired.
ステップS2711において、制御部2132は、フラグ値Fe=0であるか否か判定する。すなわち、放射線撮影装置2060の移動先の区域が無線可能区域であるか否かを判定する。フラグ値Fe=0である場合、ステップS2712へ進む。一方、フラグ値Fe=0でない場合(Fe=1である場合、すなわち無線/有線切替区域である場合)、ステップS2716へ進む。
In step S2711, the control unit 2132 determines whether or not the flag value Fe = 0. That is, it is determined whether or not the area to which the radiation imaging apparatus 2060 is moved is a wireless area. If the flag value Fe = 0, the process proceeds to step S2712. On the other hand, when the flag value is not Fe = 0 (when Fe = 1, that is, when the area is a wireless / wired switching area), the process proceeds to step S2716.
ステップS2712において、制御部2132は、有線または無線の設定と区域情報とが適切か否かを判定し、撮影ができる状況であれば、ステップS2713へ進み、無線または有線で撮影を実施する。一方、撮影ができない状況であれば、ステップS2705に戻る。
In step S2712, the control unit 2132 determines whether the wired or wireless setting and the area information are appropriate. If it is possible to perform photographing, the control unit 2132 proceeds to step S2713 and performs wireless or wired photographing. On the other hand, if the situation is that shooting is not possible, the process returns to step S2705.
ステップS2716において、制御部2132は、切替前処理を実行する。現在無線通信を行っている場合は、無線通信の継続時間を推測する。画像情報のような情報量の大きいデータを通信している場合は一旦中断し、追加オーダー情報のように情報量の少ない場合は継続する。
In step S2716, the control unit 2132 executes pre-switching processing. If wireless communication is currently being performed, the duration of wireless communication is estimated. When data with a large amount of information such as image information is being communicated, the data is temporarily interrupted, and when the amount of information is small, such as additional order information, it is continued.
通信内容が放射線撮影部2050からの画像情報転送である場合には放射線撮影部2050に対して内部メモリに画像を保存するように指示した後に中断する。外部の管理システム等の外部機器との間での画像転送である場合は、中断する旨を管理システムに送信するとともに、放射線撮影装置2060の内部の未送信メモリに画像データを保存する。何らかの障害により無線通信の状態が悪い場合も同様に処理を中断する。
When the communication content is image information transfer from the radiation imaging unit 2050, the radiography unit 2050 is instructed to save the image in the internal memory, and then interrupted. In the case of image transfer with an external device such as an external management system, a message to the effect of interruption is transmitted to the management system, and image data is stored in an untransmitted memory inside the radiation imaging apparatus 2060. The processing is similarly interrupted when the state of wireless communication is bad due to some trouble.
ステップS2717において、制御部2132は、無線通信が終了した後、有線接続への切替指示のためのアナウンスを行う。処理が正常に終了できなかった場合には、その旨のメッセージを表示もしくは報知してもよい。
In step S2717, the control unit 2132 makes an announcement for an instruction to switch to wired connection after wireless communication is completed. If the process cannot be completed normally, a message to that effect may be displayed or notified.
ステップS2718において、操作者は、切替指示に従って無線から有線への切り替えを行う。切替え作業は本体から延在しているケーブル2161のコネクタ2162と、放射線撮影部2050のコネクタ2008とを接続することにより行う。有線ケーブルが接続されたことを検知すると自動的に有線通信に切り替わる。
In step S2718, the operator switches from wireless to wired according to the switching instruction. The switching operation is performed by connecting the connector 2162 of the cable 2161 extending from the main body and the connector 2008 of the radiation imaging unit 2050. When it detects that a wired cable is connected, it automatically switches to wired communication.
以上説明したように、本実施形態では、無線または有線を切替え、無線制限区域では無線通信を制限するとともに有線通信を使用する。これにより、操作者が意識せずとも無線通信の制限を遵守して、院内等の他の機器への影響を低減することが可能となる。
As described above, in this embodiment, wireless or wired is switched, and wireless communication is restricted and wired communication is used in the wireless restricted area. As a result, it is possible to reduce the influence on other devices such as in-hospitals by observing restrictions on wireless communication without being conscious of the operator.
<<実施形態9>>
図28及び図29を参照して、実施形態9について説明する。本実施形態では、無線通信の制限を区域ごとに把握できるように構成する例を説明する。なお、放射線撮影装置や放射線撮影部を構成する共通の要素に関しては、実施形態7と同じ参照符号を用いている。 << Ninth Embodiment >>
The ninth embodiment will be described with reference to FIGS. 28 and 29. FIG. In this embodiment, an example will be described in which the restriction of wireless communication can be grasped for each area. Note that the same reference numerals as those in the seventh embodiment are used for common elements constituting the radiation imaging apparatus and the radiation imaging unit.

The ninth embodiment will be described with reference to FIGS. 28 and 29. FIG. In this embodiment, an example will be described in which the restriction of wireless communication can be grasped for each area. Note that the same reference numerals as those in the seventh embodiment are used for common elements constituting the radiation imaging apparatus and the radiation imaging unit.
図28は、本実施形態に係る撮影オーダー管理リストの一例を示す図である。制御部2132は、撮影場所2801(撮影区域情報)と無線制限の有無を示す通信形態2802とを関連付けて各対応関係を情報テーブルとして管理する。撮影区域がA棟の1F、2F、3F、B棟の3F、4Fでは通信形態は無線通信であり、B棟の1F、2F(ICU)では有線通信である。
FIG. 28 is a diagram showing an example of a shooting order management list according to the present embodiment. The control unit 2132 associates the shooting location 2801 (shooting area information) with the communication form 2802 indicating the presence or absence of wireless restriction, and manages each correspondence as an information table. When the shooting areas are 1F, 2F, 3F of Building A, 3F, 4F of Building B, the communication mode is wireless communication, and when the shooting area is 1F, 2F (ICU) of Building B, wired communication.
情報テーブルは、入出力部2133を介して操作者により編集、登録、削除等の入力可能に構成する。たとえば入出力部2133のモニタ上に表示されたインタフェースを使用して入力を行う。制御部2132は、撮影オーダーに含まれる撮影場所情報と、情報テーブルとから、各撮影オーダーに対して撮影で使用すべき通信形態を決定する。
The information table is configured so that an operator can input edits, registrations, deletions, and the like via the input / output unit 2133. For example, input is performed using an interface displayed on the monitor of the input / output unit 2133. The control unit 2132 determines the communication mode to be used for shooting for each shooting order from the shooting location information included in the shooting order and the information table.
図29は、本実施形態に係る入出力部2133(表示部)の表示例を示す。検査ID、患者IDや氏名、撮影オーダー、撮影場所、通信形態の組み合わせが撮影オーダー管理用ワークリストとして表示制御されている。たとえばA棟の2Fは無線可能エリアに登録されており、A205で示される病室での撮影は無線通信が可能である。A205の行の右部には無線通信可能であることを示すアイコン(4本の長さの異なる縦線)が表示されており、操作者はこのアイコンを確認することで有線または無線を判断することができる。これに対して、ICU01の行の右部には有線通信すべきことを示すアイコン(ケーブルを模した図形)が表示されている。
FIG. 29 shows a display example of the input / output unit 2133 (display unit) according to the present embodiment. A combination of examination ID, patient ID and name, imaging order, imaging location, and communication form is displayed and controlled as an imaging order management work list. For example, 2F of Building A is registered in the wireless area, and radio communication is possible for the imaging in the hospital room indicated by A205. An icon indicating that wireless communication is possible (four vertical lines having different lengths) is displayed on the right side of the row of A205, and the operator determines whether wired or wireless by checking this icon. be able to. On the other hand, an icon (a figure imitating a cable) indicating that wired communication is to be performed is displayed on the right side of the row of ICU01.
なお、現状の通信形態が適切な設定かどうかを認識できるように、異なるカラーやコントラストでアイコンを表示してもよい。たとえば、適切な場合は緑、不適切な場合は赤でアイコンを表示したり、不適切な場合には適切な場合よりもコントラストを下げてアイコンの表示を薄くしたりしてもよい。また、操作者が次の撮影をオーダーリストから選択した場合に、通信形態が適切でない場合、切り替えを促すようなメッセージを表示または音声で報知してもよい。このように現状の通信形態が撮影オーダー毎に適切か否かを確認しやすくすることで、不適切な使用を防ぐことができる。さらに、撮影オーダー管理用ワークリストをソートする機能を有していてもよい。たとえば無線通信が使用可能な区域をソートで抽出して表示することで、操作者は効率的なルート検討が可能となる。
Note that icons may be displayed in different colors and contrasts so that it can be recognized whether the current communication form is an appropriate setting. For example, the icon may be displayed in green when appropriate, red in inappropriate, or the icon may be displayed lighter with lower contrast than appropriate when inappropriate. Further, when the operator selects the next shooting from the order list, if the communication mode is not appropriate, a message that prompts switching may be displayed or voiced. Thus, by making it easy to confirm whether or not the current communication form is appropriate for each shooting order, inappropriate use can be prevented. Further, it may have a function of sorting the shooting order management work list. For example, by extracting and displaying areas where wireless communication can be used, the operator can efficiently examine routes.
以上本発明の実施形態について説明してきたが、さらに以下の処理を実施してもよい。具体的には、無線通信が制限される区域について、使用不可能な周波数や使用不可能な周波数を入出力部2133の表示部に表示してもよい。たとえば、「2.4GHzは使用可能であるが5GHzは使用不可能である」、「IEEE802.11bは使用可能であるがIEEE802.11aは使用不可能である」といった情報を表示してもよい。
Although the embodiment of the present invention has been described above, the following processing may be further performed. Specifically, for an area where wireless communication is restricted, an unusable frequency or an unusable frequency may be displayed on the display unit of the input / output unit 2133. For example, information such as “2.4 GHz is usable but 5 GHz is unusable” and “IEEE802.11b is usable but IEEE802.11a is unusable” may be displayed.
また、RISから撮影オーダーを取得した際に、撮影オーダーに対応する撮影区域に無線通信制限区域が含まれる場合、回診時に有線ケーブルが必要になることを操作者に報知してもよい。
In addition, when the radiographing order is acquired from the RIS, if the radiocommunication restricted area is included in the radiographing area corresponding to the radiographing order, the operator may be informed that a wired cable is required at the roundabout.
さらに、無線通信が制限される区域において放射線撮影部と放射線撮影装置本体とが有線ケーブルで接続されていない場合には、操作者に有線ケーブルの接続を促すために警告を報知してもよい。これに加えてまたはこれに代えて、放射線撮影を禁止してもよい。たとえば、撮影条件の入力受付を不可に制御したり、曝射スイッチを押下できないようにロックしたり、曝射スイッチを押下しても反応しないように制御したりしてもよい。
Furthermore, when the radiographic unit and the radiographic apparatus main body are not connected by a wired cable in an area where wireless communication is restricted, a warning may be notified to prompt the operator to connect the wired cable. In addition to or instead of this, radiography may be prohibited. For example, the reception of imaging conditions may be controlled to be unacceptable, the exposure switch may be locked so that the exposure switch cannot be pressed, or the exposure switch may be controlled so as not to react even if the exposure switch is pressed.
無線通信が制限されている場合であっても緊急時には撮影を行いたい場合がある。そのため、緊急時を想定して無線通信を許可するための入力を受け付ける物理的なボタンを設けてもよい。なお物理的なボタンに限らず、入出力部にGUIを構成して、タッチパネル等に仮想ボタンを設けてもよい。
Even if wireless communication is restricted, you may want to take a picture in an emergency. Therefore, a physical button that accepts an input for permitting wireless communication in an emergency may be provided. In addition to the physical buttons, a virtual button may be provided on a touch panel or the like by configuring a GUI in the input / output unit.
また、ある区域から別の区域への進入または退出の検知のために、2つの発信装置を区域の出入り口付近に所定距離離間した状態で配置してもよい。各発信装置から発信される2つの情報を受信して各受信強度の変化に基づいて放射線撮影装置の移動方向を判定することにより、進入または退出を認識するように構成してもよい。
Also, in order to detect entry or exit from one area to another area, two transmitters may be arranged in the vicinity of the area entrance / exit at a predetermined distance. You may comprise so that an approach or exit may be recognized by receiving two information transmitted from each transmitter, and determining the moving direction of a radiography apparatus based on the change of each received intensity.

また、本発明は、以下の処理を実行することによっても実現される。即ち、上述した実施形態の機能を実現するソフトウェア(プログラム)を、ネットワーク又は各種記憶媒体を介してシステム或いは装置に供給し、そのシステム或いは装置のコンピュータ(またはCPUやMPU等)がプログラムを読み出して実行する処理である。 (Other embodiments)
The present invention can also be realized by executing the following processing.
