Description

放射線画像撮影システムRadiation imaging system
　本発明は、放射線画像撮影システムに関する。 The present invention relates to a radiographic image capturing system.
　従来、病気診断等を目的として、Ｘ線画像に代表される、放射線を用いて撮影された放射線画像が広く用いられている。こうした医療用の放射線画像は、従来スクリーンフィルムを用いて撮影されていたが、近年は、放射線画像のデジタル化が実現されており、例えば、被写体を透過した放射線を輝尽性蛍光体層が形成された輝尽性蛍光体シートに蓄積させた後、この輝尽性蛍光体シートをレーザ光で走査し、これにより輝尽性蛍光体シートから発光される輝尽光を光電変換して画像データを得るＣＲ（Computed Radiography）撮影装置が広く普及している。 Conventionally, for the purpose of disease diagnosis and the like, a radiographic image taken using radiation, which is typified by an X-ray image, has been widely used. Such medical radiographic images were conventionally taken using a screen film, but in recent years, digitization of radiographic images has been realized. For example, a stimulable phosphor layer forms radiation transmitted through a subject. After being stored in the photostimulable phosphor sheet, the photostimulable phosphor sheet is scanned with laser light, and thereby the photostimulated light emitted from the photostimulable phosphor sheet is photoelectrically converted to image data. A CR (Computed Radiography) imaging device that obtains a widespread use is widely used.
　また、最近では、医療用の放射線画像を得る手段として、照射された放射線を検出しデジタル画像データとして取得するＦＰＤ（Flat Panel Detector）が知られており、ＦＰＤを用いた撮影装置が実用化されるようになってきた。 Recently, as a means for obtaining a medical radiation image, an FPD (Flat Panel Detector) that detects irradiated radiation and acquires it as digital image data is known, and an imaging apparatus using the FPD has been put into practical use. It has come to be.
　ＦＰＤ撮影装置は、例えば、照射された放射線を光に変換するシンチレータとこの光を電気信号に変換するフォトダイオード等の光電変換素子を有し、光電変換素子に蓄積された電気信号を読み出して画像データを得るようになっている。 The FPD imaging apparatus has, for example, a scintillator that converts irradiated radiation into light and a photoelectric conversion element such as a photodiode that converts this light into an electrical signal, and reads out an electrical signal accumulated in the photoelectric conversion element to generate an image. Get data.
　ＦＰＤ撮影装置では、ＣＲ撮影装置と比較して少ない放射線量で同等の画質の画像を得ることができるため、患者の被曝量の低減が可能である。また、ＦＰＤの改良により、従来より感度が高く、より少ない放射線量で従来のＦＰＤと同等の画質の画像を得ることが可能なＦＰＤも登場している。 Since the FPD imaging device can obtain an image with the same image quality with a smaller radiation dose than the CR imaging device, it is possible to reduce the exposure dose of the patient. In addition, FPDs that have higher sensitivity than conventional ones and can obtain an image having the same image quality as conventional FPDs with a smaller amount of radiation have also appeared.
　そのため、近年では、特許文献１に記載のように、ＣＲ撮影装置やＦＰＤ撮影装置が混在するシステムや、異なる種類のＦＰＤ装置が混在するシステムも利用されている。 Therefore, in recent years, as described in Patent Document 1, a system in which CR imaging devices and FPD imaging devices are mixed and a system in which different types of FPD devices are mixed are also used.
特開２００１－１４９３５８号公報JP 2001-149358 A
　ところで、ＣＲ撮影装置とＦＰＤ撮影装置が混在するシステムにおいて、ＦＰＤ撮影装置に対してＣＲ撮影装置と同じ放射線量で撮影を行うと、本来ＦＰＤ撮影装置で診断に必要な画質の画像を得るために必要な線量に対して過剰に放射線が照射されてしまい、患者の被曝線量低減というメリットが得られなくなってしまうという問題がある。また、ＦＰＤ撮影装置はＣＲ撮影装置に比べてダイナミックレンジが狭いという特性があるため、過剰な放射線量で撮影を行うと画像の一部の画素の信号値が飽和してしまい、高精度な診断情報（画像）が得られなくなってしまう恐れがある。逆に、ＦＰＤ撮影装置に合わせた放射線量で撮影を行うと、ＣＲ撮影装置では線量が不十分であり、Ｓ／Ｎ比が低下するため画像処理を行っても、高精度な診断情報（画像）を得ることができない恐れがある。
　異なる種類のＦＰＤ撮影装置が混在するシステムにおいても、同様の問題が発生する。 By the way, in a system in which a CR imaging device and an FPD imaging device coexist, when the FPD imaging device performs imaging with the same radiation dose as that of the CR imaging device, in order to obtain an image of an image quality originally necessary for diagnosis by the FPD imaging device. There is a problem that radiation is excessively applied to the necessary dose, and the merit of reducing the patient's exposure dose cannot be obtained. In addition, since the FPD imaging device has a characteristic that the dynamic range is narrower than that of the CR imaging device, when imaging is performed with an excessive radiation dose, the signal value of some pixels of the image is saturated, and high-accuracy diagnosis is performed. Information (image) may not be obtained. Conversely, when imaging is performed with a radiation dose that matches the FPD imaging apparatus, the CR imaging apparatus has insufficient dose, and the S / N ratio decreases, so even if image processing is performed, highly accurate diagnostic information (image ) You may not get.
The same problem occurs in a system in which different types of FPD photographing apparatuses are mixed.
　上記問題は、放射線発生装置を制御するコンソールにおいて、使用する撮影装置の種類に応じて最適な放射線照射条件を設定し、設定した放射線照射条件で撮影を行うことで解決することができる。コンソールは、技師等の撮影実施者の被曝を防止するため、撮影室外に設置されているのが通常である。しかし、コンソールにおいて一旦放射線照射条件を設定した後、撮影室内において撮影装置の変更が生じた場合、例えば、立位撮影用のＦＰＤ装置と臥位撮影用のＣＲ撮影装置が存在するシステムにおいて、立位の撮影を行う予定であったが患者が車椅子で立位では撮影できないので臥位のＣＲ撮影装置に変更する必要が生じたような場合、撮影実施者は、一旦撮影室を出てコンソールで放射線発生装置の放射線照射条件の設定を変更する操作が必要となり、効率的な撮影を行うことができない。 The above problem can be solved by setting an optimal radiation irradiation condition according to the type of imaging apparatus to be used in the console for controlling the radiation generating apparatus, and performing imaging under the set radiation irradiation condition. The console is usually installed outside the photographing room in order to prevent exposure of a photographer such as an engineer. However, once the radiation irradiation conditions are set in the console and the imaging apparatus is changed in the imaging room, for example, in a system including an FPD apparatus for standing imaging and a CR imaging apparatus for lying imaging. However, if the patient needs to switch to a supine CR imaging device because the patient cannot take a picture in a standing position in a wheelchair, the person who performed the imaging should leave the imaging room and use the console. An operation for changing the setting of the radiation irradiation condition of the radiation generating apparatus is required, and efficient imaging cannot be performed.
　本発明の課題は、撮影装置の種類に変更が生じた場合に撮影室内で容易に放射線照射条件の変更操作が行えるようにすることである。 It is an object of the present invention to make it possible to easily change the radiation irradiation condition in the photographing room when the kind of the photographing device is changed.

As shown in FIG. 3, the console 5 includes a control unit 51, a storage unit 52, an input unit 53, a display unit 54, a wireless communication unit 55, a network communication unit 56, an I / F57 etc. are provided and each part is connected by the bus | bath 58. FIG.
　制御部５１は、ＣＰＵ、ＲＡＭ等により構成される。制御部５１のＣＰＵは、記憶部５２に記憶されているシステムプログラムや処理プログラム等の各種プログラムを読み出してＲＡＭに展開し、展開されたプログラムに従って各種処理を実行するコンソール５の制御手段である。
　例えば、制御部５１は、後述する放射線照射制御処理を実行する。また、制御部５１は、所定時間毎にネットワーク通信部５６を介してＲＩＳ／ＨＩＳ６に問い合わせを行い、新たにＲＩＳ／ＨＩＳ６で登録された撮影オーダ情報を取得する。 The control unit 51 includes a CPU, a RAM, and the like. The CPU of the control unit 51 is a control unit of the console 5 that reads out various programs such as a system program and a processing program stored in the storage unit 52, expands them in a RAM, and executes various processes according to the expanded programs.
For example, the control unit 51 executes a radiation irradiation control process described later. In addition, the control unit 51 makes an inquiry to the RIS / HIS 6 via the network communication unit 56 every predetermined time, and acquires imaging order information newly registered in the RIS / HIS 6.
　記憶部５２は、例えばＨＤＤ（Hard Disk Drive）や半導体の不揮発性メモリ等で構成されている。記憶部５２には、画像データから患部を検出するための自動部位認識に基づく階調処理・周波数処理等の画像処理を行うためのプログラム等、各種のプログラムが記憶されているほか、撮影画像の画像データを診断に適した画質に調整するための画像処理パラメータ（階調処理に用いる階調曲線を定義したルックアップテーブル、周波数処理の強調度等）等が記憶されている。 The storage unit 52 includes, for example, an HDD (Hard Disk Drive), a semiconductor nonvolatile memory, or the like. The storage unit 52 stores various programs such as a program for performing image processing such as gradation processing and frequency processing based on automatic region recognition for detecting an affected area from image data, and also stores captured images. Stored are image processing parameters for adjusting image data to an image quality suitable for diagnosis (lookup table defining a gradation curve used for gradation processing, enhancement degree of frequency processing, and the like).
　また、記憶部５２には、照射条件テーブル５２１が記憶されている。照射条件テーブル５２１には、撮影部位毎に、ＦＰＤ撮影装置１用とＣＲ撮影装置２用のそれぞれの放射線照射条件が記憶されている。ここで、一般的に、ＦＰＤでは、ＣＲと比較して低い放射線照射量でＣＲと同等の画質を得ることができる。そこで、照射条件テーブル５２１には、放射線発生装置３における照射放射線量がＦＰＤ撮影装置１＜ＣＲ撮影装置２となるように、それぞれの放射線照射条件が設定されている。
　なお、照射条件テーブル５２１には、撮影部位毎に、基準となる撮影装置（例えば、ＣＲ撮影装置２）の放射線照射条件と、他方の撮影装置（例えばＦＰＤ撮影装置１）の照射条件算出用の補正値（例えば、照射時間を基準の５０％とする等）が記憶されることとしてもよい。 In addition, the storage unit 52 stores an irradiation condition table 521. The irradiation condition table 521 stores radiation irradiation conditions for the FPD imaging apparatus 1 and the CR imaging apparatus 2 for each imaging region. Here, in general, with FPD, an image quality equivalent to that of CR can be obtained with a lower radiation dose than CR. Therefore, the radiation condition is set in the irradiation condition table 521 so that the radiation dose in the radiation generator 3 is FPD imaging device 1 <CR imaging device 2.
In the irradiation condition table 521, the radiation irradiation condition of the reference imaging apparatus (for example, the CR imaging apparatus 2) and the irradiation condition calculation of the other imaging apparatus (for example, the FPD imaging apparatus 1) are calculated for each imaging region. A correction value (for example, the irradiation time is set to 50% of the reference) may be stored.
　また、記憶部５２には、撮影装置決定テーブル５２２が記憶されている。撮影装置決定テーブル５２２には、立位、臥位のそれぞれに対応する撮影装置の種類の情報が記憶されている。本実施の形態では、立位にＦＰＤ撮影装置１が、臥位にＣＲ撮影装置２が対応付けられている。 Also, the storage unit 52 stores an imaging device determination table 522. The imaging device determination table 522 stores information on the types of imaging devices corresponding to the standing position and the lying position. In the present embodiment, the FPD photographing apparatus 1 is associated with the standing position, and the CR photographing apparatus 2 is associated with the lying position.
　入力部５３は、文字入力キー、数字入力キー、及び各種機能キー等を備えたキーボードと、マウス等のポインティングデバイスを備えて構成され、キーボードで押下操作されたキーの押下信号とマウスによる操作信号とを、入力信号として制御部５１に出力する。また、入力部５３は、撮影実施者が放射線照射の指示を入力するための放射線照射スイッチを備えている。 The input unit 53 includes a keyboard having character input keys, numeric input keys, various function keys, and the like, and a pointing device such as a mouse, and a key pressing signal pressed by the keyboard and an operation signal by the mouse. Are output to the control unit 51 as an input signal. In addition, the input unit 53 includes a radiation irradiation switch for allowing a radiographer to input a radiation irradiation instruction.
　表示部５４は、例えば、ＣＲＴ（Cathode Ray Tube）やＬＣＤ（Liquid Crystal Display）等のモニタを備えて構成されており、制御部５１から入力される表示信号の指示に従って、各種画面を表示する。
　なお、表示部５４の画面上に、透明電極を格子状に配置した感圧式（抵抗膜圧式）のタッチパネル（図示せず）を形成し、表示部５４と入力部５３とが一体に構成されるタッチスクリーンとしてもよい。この場合、タッチパネルは、手指やタッチペン等で押下された力点のＸＹ座標を電圧値で検出し、検出された位置信号が操作信号として制御部５１に出力されるように構成される。なお、表示部５４は、一般的なＰＣ（Personal Computer）に用いられるモニタよりも高精細のものであってもよい。 The display unit 54 includes a monitor such as a CRT (Cathode Ray Tube) or an LCD (Liquid Crystal Display), for example, and displays various screens according to instructions of display signals input from the control unit 51.
A pressure-sensitive (resistive film pressure type) touch panel (not shown) in which transparent electrodes are arranged in a grid pattern is formed on the screen of the display unit 54, and the display unit 54 and the input unit 53 are configured integrally. It may be a touch screen. In this case, the touch panel is configured to detect the XY coordinates of the power point pressed by a finger, a touch pen, or the like as a voltage value, and output the detected position signal to the control unit 51 as an operation signal. The display unit 54 may have a higher definition than a monitor used in a general PC (Personal Computer).
　無線通信部５５は、無線アクセスポイント４を介してＦＰＤ撮影装置１のＦＰＤカセッテ１ｂと情報の送受信を行うものである。本実施形態において、無線通信部５５は無線アクセスポイント４を介して定期的にＦＰＤカセッテ１ｂに対してポーリング信号を送信する。 The wireless communication unit 55 transmits / receives information to / from the FPD cassette 1b of the FPD photographing apparatus 1 via the wireless access point 4. In the present embodiment, the wireless communication unit 55 periodically transmits a polling signal to the FPD cassette 1b via the wireless access point 4.

Note that the imaging order information is not limited to the information exemplified here, but may include other information, or may be a part of the information exemplified above.
The PACS 7 stores the image data output from the console 5.
（放射線画像撮影システム１００の動作）
　次に、放射線画像撮影システム１００の動作について、技師等の撮影実施者の作業と併せて説明する。
　図４に、コンソール５により実行される放射線照射制御処理のフローチャートを示す。放射線照射制御処理は、制御部５１と記憶部５２に記憶されているプログラムとの協働により実行される。 (Operation of Radiation Imaging System 100)
Next, the operation of the radiographic image capturing system 100 will be described together with the work of a radiographer such as an engineer.
FIG. 4 shows a flowchart of the radiation irradiation control process executed by the console 5. The radiation irradiation control process is executed in cooperation with the control unit 51 and a program stored in the storage unit 52.
　まず、撮影実施者は、前室Ｒ２において、コンソール５の入力部５３を操作して撮影オーダ情報の一覧を表示する撮影オーダリスト画面を表示部５４に表示させる。そして、入力部５３を操作することにより撮影オーダリスト画面から撮影対象の撮影オーダ情報を指定する。 First, the shooter operates the input unit 53 of the console 5 in the front room R2 to display a shooting order list screen for displaying a list of shooting order information on the display unit 54. Then, by operating the input unit 53, the imaging order information of the imaging target is designated from the imaging order list screen.
　コンソール５においては、入力部５３により撮影対象の撮影オーダ情報が指定されると（ステップＳ１）、記憶部５２の撮影装置決定テーブル５２２が参照され、指定された撮影オーダ情報に応じた撮影装置（ＦＰＤ撮影装置１又はＣＲ撮影装置２）が選択される（ステップＳ２）。そして、記憶部５２の照射条件テーブル５２１が参照され、選択された撮影装置に対応する放射線照射条件の情報がＩ／Ｆ５７を介して放射線発生装置３に送信されて設定される（ステップＳ３）。 In the console 5, when shooting order information to be shot is specified by the input unit 53 (step S1), the shooting device determination table 522 of the storage unit 52 is referred to and a shooting device (in accordance with the specified shooting order information ( The FPD photographing device 1 or the CR photographing device 2) is selected (step S2). Then, the irradiation condition table 521 of the storage unit 52 is referred to, and information on the radiation irradiation conditions corresponding to the selected imaging apparatus is transmitted to the radiation generation apparatus 3 via the I / F 57 and set (step S3).
　撮影実施者は、撮影対象の撮影オーダ情報を指定すると、撮影室Ｒ１に移動し、撮影に用いる撮影装置の撮影台の高さを調整する等して患者Ｍの被写体となる部位を撮影台に配置する。撮影台の高さの調整値はコンソール５に出力され、コンソール５により放射線発生装置３の位置が制御される。このとき、例えば、撮影オーダ情報では立位で撮影することとなっているが患者Ｍが車椅子を使用していて立つことができない等、撮影装置の種類を変更する必要が生じる場合がある。この場合、撮影実施者は、撮影装置の種類の変更をコンソール５に通知するための操作を行う。本実施の形態においては、撮影装置の種類の変更をコンソール５に通知することを指示するための操作手段として、起動スイッチ１２を用いる。例えば、ＦＰＤ撮影装置１からＣＲ撮影装置２に変更する場合には、ＦＰＤカセッテ１ｂの起動スイッチ１２をＯＮからＯＦＦに切り換え操作する。ＣＲ撮影装置２からＦＰＤ撮影装置１に変更する場合は、ＦＰＤカセッテ１ｂの起動スイッチ１２をＯＦＦからＯＮに切り換え操作する。なお、撮影装置の種類の変更を通知するためのスイッチとして、電源スイッチ１８を用いてもよい。即ち、ＦＰＤ撮影装置１からＣＲ撮影装置２に変更する場合には、ＦＰＤカセッテ１ｂの電源スイッチ１８をＯＮからＯＦＦに切り換え、ＣＲ撮影装置２からＦＰＤ撮影装置１に変更する場合は、ＦＰＤカセッテ１ｂの電源スイッチ１８をＯＦＦからＯＮに切り換え操作するようにしてもよい。 When the radiographer designates radiographing order information to be radiographed, the radiographer moves to the radiographing room R1 and adjusts the height of the radiographing base of the radiographing apparatus used for radiographing, so that the part that becomes the subject of the patient M becomes the radiographic stand Deploy. The adjustment value of the height of the imaging table is output to the console 5, and the position of the radiation generator 3 is controlled by the console 5. At this time, for example, it is necessary to change the type of the imaging device such that the patient M cannot stand while using the wheelchair although the imaging order information is to take an image while standing. In this case, the photographer performs an operation for notifying the console 5 of a change in the type of the photographing apparatus. In the present embodiment, the activation switch 12 is used as an operation unit for instructing the console 5 to notify the console 5 of the change in the type of the photographing apparatus. For example, when changing from the FPD imaging device 1 to the CR imaging device 2, the activation switch 12 of the FPD cassette 1b is switched from ON to OFF. When changing from the CR photographing device 2 to the FPD photographing device 1, the activation switch 12 of the FPD cassette 1b is switched from OFF to ON. Note that the power switch 18 may be used as a switch for notifying the change of the type of the photographing apparatus. That is, when changing from the FPD imaging device 1 to the CR imaging device 2, the power switch 18 of the FPD cassette 1b is switched from ON to OFF, and when changing from the CR imaging device 2 to the FPD imaging device 1, the FPD cassette 1b. The power switch 18 may be switched from OFF to ON.
　コンソール５においては、撮影装置の種類の変更が検知されたか否かの判断が行われる（ステップＳ４）。例えば、ステップＳ２において撮影装置としてＦＰＤ撮影装置１が選択された場合においては、無線通信部５５によるＦＰＤカセッテ１ｂへのポーリング信号に対する応答信号が受信されている状態から無応答になったことが検知されると、撮影装置の種類の変更が検知されたと判断される。ステップＳ２において撮影装置としてＣＲ撮影装置２が選択された場合においては、無線通信部５５によるＦＰＤカセッテ１ｂへのポーリング信号に対する応答信号が無応答から応答受信状態となったことが検知されると、撮影装置の種類の変更が検知されたと判断される。 In the console 5, it is determined whether or not a change in the type of the photographing apparatus has been detected (step S4). For example, when the FPD imaging device 1 is selected as the imaging device in step S2, it is detected that there is no response from the state where the response signal to the polling signal to the FPD cassette 1b by the wireless communication unit 55 is received. Then, it is determined that a change in the type of the photographing apparatus has been detected. When the CR imaging device 2 is selected as the imaging device in step S2, when it is detected that the response signal for the polling signal to the FPD cassette 1b by the wireless communication unit 55 has changed from no response to a response reception state, It is determined that a change in the type of the photographing apparatus has been detected.
　撮影装置の種類の変更が検知されていないと判断されると（ステップＳ４；ＮＯ）、撮影に用いる撮影装置の種類及び撮影実施者による位置調整に応じて、放射線発生装置３の位置が調整される（ステップＳ６）。そして、入力部５３の放射線照射スイッチが押下されたか否かが判断され（ステップＳ７）、放射線照射スイッチが押下されていないと判断されると（ステップＳ７；ＮＯ）、処理はステップＳ４に戻る。放射線照射スイッチが押下されたと判断されると（ステップＳ７；ＹＥＳ）、放射線発生装置３に放射線照射の指示信号が送信され、設定された放射線照射条件で放射線が照射され（ステップＳ８）、放射線照射制御処理は終了する。 If it is determined that a change in the type of the imaging device has not been detected (step S4; NO), the position of the radiation generator 3 is adjusted according to the type of imaging device used for imaging and the position adjustment by the imaging operator. (Step S6). Then, it is determined whether or not the radiation irradiation switch of the input unit 53 has been pressed (step S7). If it is determined that the radiation irradiation switch has not been pressed (step S7; NO), the process returns to step S4. If it is determined that the radiation irradiation switch has been pressed (step S7; YES), a radiation irradiation instruction signal is transmitted to the radiation generator 3, and radiation is irradiated under the set radiation irradiation conditions (step S8). The control process ends.
　一方、撮影装置の種類の変更が検知されたと判断されると（ステップＳ４；ＹＥＳ）、ステップＳ２で選択された装置とは異なる他方の撮影装置に対応する放射線照射条件が放射線発生装置３に送信され、放射線発生装置３の放射線照射条件が設定変更される（ステップＳ５）。また、撮影に用いる撮影装置の種類及び撮影実施者による位置調整に応じて、放射線発生装置３の位置が調整される（ステップＳ６）。そして、入力部５３の放射線照射スイッチが押下されたか否かが判断され（ステップＳ７）、放射線照射スイッチが押下されていないと判断されると（ステップＳ７；ＮＯ）、処理はステップＳ４に戻る。放射線照射スイッチが押下されたと判断されると（ステップＳ７；ＹＥＳ）、Ｉ／Ｆ５７を介して放射線発生装置３に放射線照射の指示信号が送信され、設定された放射線照射条件で放射線が照射され（ステップＳ８）、放射線照射制御処理は終了する。 On the other hand, if it is determined that a change in the type of the imaging apparatus has been detected (step S4; YES), radiation irradiation conditions corresponding to the other imaging apparatus different from the apparatus selected in step S2 are transmitted to the radiation generation apparatus 3. Then, the radiation irradiation conditions of the radiation generator 3 are set and changed (step S5). Further, the position of the radiation generating apparatus 3 is adjusted according to the type of the imaging apparatus used for imaging and the position adjustment by the imaging operator (step S6). Then, it is determined whether or not the radiation irradiation switch of the input unit 53 has been pressed (step S7). If it is determined that the radiation irradiation switch has not been pressed (step S7; NO), the process returns to step S4. If it is determined that the radiation irradiation switch has been pressed (step S7; YES), a radiation irradiation instruction signal is transmitted to the radiation generation apparatus 3 via the I / F 57, and radiation is irradiated under the set radiation irradiation conditions ( Step S8), the radiation irradiation control process ends.
　以上のように、第１の実施の形態においては、ＦＰＤ撮影装置１とＣＲ撮影装置２を備えた放射線画像撮影システム１００において、コンソール５での撮影装置の選択後に撮影室Ｒ１内に設けられた、撮影装置の種類の変更をコンソール５に通知する指示を入力するための操作手段、例えば、ＦＰＤカセッテ１ｂの起動スイッチ１２が操作されると、コンソール５は、操作手段から撮影装置の種類の変更指示が入力されたことを検知して放射線発生装置３の放射線照射条件等を変更先の撮影装置に応じた放射線照射条件等に変更する。従って、撮影実施者は、撮影室Ｒ１において、例えば、患者が車椅子である、撮影装置が故障している等の理由により撮影装置の種類を変更しなければならなくなった場合においても、従来のように撮影室Ｒ１から出てコンソール５を操作して放射線照射条件を手動で変更する必要がなく、撮影室Ｒ１内で容易に放射線照射条件の変更操作を行うことが可能となる。その結果、撮影装置の変更が生じてもスムーズに撮影を進行させることが可能となり、撮影効率を向上させることが可能となる。 As described above, in the first embodiment, in the radiographic imaging system 100 including the FPD imaging device 1 and the CR imaging device 2, the radiographic imaging system 100 is provided in the imaging room R <b> 1 after the selection of the imaging device on the console 5. When the operation means for inputting an instruction for notifying the console 5 of the change in the type of the photographing apparatus, for example, the start switch 12 of the FPD cassette 1b is operated, the console 5 changes the type of the photographing apparatus from the operation means. Upon detecting that an instruction has been input, the radiation irradiation condition of the radiation generating device 3 is changed to a radiation irradiation condition or the like corresponding to the change-destination imaging apparatus. Therefore, even when the photographer has to change the type of the photographing apparatus in the photographing room R1, for example, because the patient is a wheelchair or the photographing apparatus is out of order. Thus, it is not necessary to change the radiation irradiation condition manually by leaving the imaging room R1 and operating the console 5 to change the radiation irradiation condition easily in the imaging room R1. As a result, even if the photographing apparatus is changed, photographing can be performed smoothly, and photographing efficiency can be improved.
　なお、一人の患者に対し、例えば、胸部正面と胸部側面のように、２つの撮影オーダがある場合、上記実施の形態においては、１回の放射線照射毎に撮影装置の種類の変更操作が必要となる。しかし、同一の撮影装置を使用する場合は、これでは操作が煩雑である。そこで、コンソール５の入力部５３に、条件継続ボタン／条件解除ボタン等を設け、放射線照射ボタンの押下のために撮影実施者が前室Ｒ２にきたとき等にこの条件継続ボタンが押下されたら、その後解除されるまでは同じ撮影装置を使用する条件で放射線発生装置３を制御するようにしてもよい。 In addition, when there are two imaging orders for one patient, for example, the front of the chest and the side of the chest, in the above embodiment, it is necessary to change the type of the imaging apparatus for each radiation irradiation. It becomes. However, when the same photographing apparatus is used, this is complicated. Therefore, if a condition continuation button / condition release button or the like is provided on the input unit 53 of the console 5 and the condition continuation button is pressed when the radiographer comes to the front room R2 to press the radiation irradiation button, The radiation generation apparatus 3 may be controlled under the condition of using the same imaging apparatus until it is released thereafter.
　また、上記第１の実施の形態においては、撮影装置の種類の変更をコンソール５に通知する指示を入力するための操作手段としてＦＰＤカセッテ１ｂの起動スイッチ１２又は電源スイッチ１８を用いることとしたが、ＦＰＤ撮影装置１の撮影台１ａを含む本体が簡易操作部１ｃを備える構成とし、この簡易操作部１ｃから撮影装置の種類の変更の指示を入力可能な構成としてもよい。また、ＣＲ撮影装置２の撮影台２ａを含む本体が簡易操作部２ｃを備える構成とし、この簡易操作部２ｃから撮影装置の種類の変更の指示を入力可能な構成としてもよい。この場合、簡易操作部１ｃ（２ｃ）から撮影装置の種類の変更の指示が入力されると、ＦＰＤ撮影装置１（ＣＲ撮影装置２）は撮影装置の種類の変更を通知する通知信号をコンソール５に出力し、コンソール５は、図４のステップＳ４において、ＦＰＤ撮影装置１（ＣＲ撮影装置２）からの通知信号の受信を検知すると、撮影装置の種類を変更する。
　このような構成とすれば、ＦＰＤ撮影装置１がＦＰＤ専用機であってもコンソール５は上記放射線照射制御処理を実行することが可能となる。 In the first embodiment, the start switch 12 or the power switch 18 of the FPD cassette 1b is used as an operation means for inputting an instruction for notifying the console 5 of a change in the type of the photographing apparatus. The main body including the photographing stand 1a of the FPD photographing apparatus 1 may be configured to include the simple operation unit 1c, and an instruction to change the type of the photographing apparatus may be input from the simple operation unit 1c. Further, the main body including the photographing stand 2a of the CR photographing device 2 may be configured to include the simple operation unit 2c, and a configuration in which an instruction to change the type of the photographing device can be input from the simple operation unit 2c. In this case, when an instruction to change the type of the imaging device is input from the simple operation unit 1c (2c), the FPD imaging device 1 (CR imaging device 2) sends a notification signal for notifying the change of the type of the imaging device to the console 5. When the console 5 detects the reception of the notification signal from the FPD imaging device 1 (CR imaging device 2) in step S4 of FIG. 4, the console 5 changes the type of the imaging device.
With such a configuration, even if the FPD imaging apparatus 1 is an FPD dedicated machine, the console 5 can execute the radiation irradiation control process.
[第２の実施の形態]
　次に、本発明の第２の実施の形態について説明する。
　まず、第２の実施の形態の構成について説明する。
　図５に、第２の実施の形態における放射線画像撮影システム２００の全体構成を示す。図５に示すように、第２の実施の形態における放射線画像撮影システム２００は、立位撮影用のＦＰＤ撮影装置８と、臥位撮影用のＦＰＤ撮影装置９と、放射線発生装置３と、無線アクセスポイント４と、コンソール５とを備えて構成されている。ＦＰＤ撮影装置８、ＦＰＤ撮影装置９、放射線発生装置３及び無線アクセスポイント４は、撮影室Ｒ１に設けられている。コンソール５は、前室Ｒ２に設けられている。コンソール５は、通信ケーブル等を介してＦＰＤ撮影装置８、ＦＰＤ撮影装置９、放射線発生装置３のそれぞれに接続されている。また、コンソール５は、ネットワークＮを介してＲＩＳ／ＨＩＳ６及びＰＡＣＳ７にデータ送受信可能に接続される。 [Second Embodiment]
Next, a second embodiment of the present invention will be described.
First, the configuration of the second embodiment will be described.
FIG. 5 shows an overall configuration of a radiographic image capturing system 200 according to the second embodiment. As shown in FIG. 5, the radiographic image capturing system 200 according to the second embodiment includes an FPD image capturing device 8 for standing position image capturing, an FPD image capturing device 9 for position image capturing, a radiation generating device 3, and a wireless device. An access point 4 and a console 5 are provided. The FPD photographing device 8, the FPD photographing device 9, the radiation generating device 3, and the wireless access point 4 are provided in the photographing room R1. The console 5 is provided in the front chamber R2. The console 5 is connected to each of the FPD imaging device 8, the FPD imaging device 9, and the radiation generating device 3 via a communication cable or the like. The console 5 is connected to the RIS / HIS 6 and the PACS 7 via the network N so that data can be transmitted and received.
　本実施の形態において、ＦＰＤ撮影装置８とＦＰＤ撮影装置９に用いられる検出部は、互いにシンチレータ種が異なる。即ち、ＦＰＤ撮影装置８又はＦＰＤ撮影装置９の何れか一方に用いられる検出部のシンチレータ種がＣｓＩ（ヨウ化セシウム）である場合、他方のシンチレータ種はＧＯＳ（希土類蛍光体）である。本実施の形態においては、ＦＰＤ撮影装置８がＣｓＩ、ＦＰＤ撮影装置９がＧＯＳとして説明する。
　なお、ＦＰＤ撮影装置８とＦＰＤ撮影装置９は、双方が上述のカセッテ型の撮影装置であっても一体型の専用機であってもよいし、カセッテ型と一体型が混在していてもよい。 In the present embodiment, the detection units used in the FPD photographing apparatus 8 and the FPD photographing apparatus 9 have different scintillator types. That is, when the scintillator species of the detection unit used in either the FPD imaging device 8 or the FPD imaging device 9 is CsI (cesium iodide), the other scintillator species is GOS (rare earth phosphor). In the present embodiment, the FPD photographing apparatus 8 will be described as CsI, and the FPD photographing apparatus 9 will be described as GOS.
Note that the FPD photographing device 8 and the FPD photographing device 9 may both be the above-described cassette type photographing device or an integrated dedicated machine, or the cassette type and the integral type may be mixed. .
　放射線画像撮影システム２００の各装置の構成は、第１の実施の形態で説明したものと略同様であるが、コンソール５の記憶部５２には、照射条件テーブル５２３、撮影装置決定テーブル５２４が記憶されている。 The configuration of each device of the radiographic imaging system 200 is substantially the same as that described in the first embodiment, but the storage unit 52 of the console 5 stores an irradiation condition table 523 and an imaging device determination table 524. Has been.
　照射条件テーブル５２３には、撮影部位毎に、ＦＰＤ撮影装置８用とＦＰＤ撮影装置９用のそれぞれの放射線照射条件が記憶されている。ここで、ＣｓＩとＧＯＳでは、ＣｓＩの方が感度が高い。そのため、ＦＰＤ撮影装置８ではＦＰＤ撮影装置９よりも低い照射線量でＦＰＤ撮影装置９と同等の画質を得ることができる。そこで、放射線発生装置３における照射放射線量がＦＰＤ撮影装置８＜ＦＰＤ撮影装置９となるように、それぞれの放射線照射条件が設定されている。
　なお、照射条件テーブル５２３には、撮影部位毎に、基準となる撮影装置（例えば、ＦＰＤ撮影装置９）の放射線照射条件と、他方の撮影装置（例えばＦＰＤ撮影装置８）の照射条件算出用の補正値（例えば、照射時間を基準の５０％とする等）が記憶されることとしてもよい。 The irradiation condition table 523 stores the radiation irradiation conditions for the FPD imaging apparatus 8 and the FPD imaging apparatus 9 for each imaging region. Here, CsI and GOS have higher sensitivity. Therefore, the FPD photographing apparatus 8 can obtain an image quality equivalent to that of the FPD photographing apparatus 9 with an irradiation dose lower than that of the FPD photographing apparatus 9. Therefore, the respective radiation irradiation conditions are set so that the radiation dose in the radiation generation device 3 is FPD imaging device 8 <FPD imaging device 9.
In the irradiation condition table 523, for each imaging region, a radiation irradiation condition for a reference imaging apparatus (for example, the FPD imaging apparatus 9) and an irradiation condition calculation for the other imaging apparatus (for example, the FPD imaging apparatus 8) are calculated. A correction value (for example, the irradiation time is set to 50% of the reference) may be stored.
　撮影装置決定テーブル５２４には、立位、臥位のそれぞれに対応する撮影装置の種類が記憶されている。本実施の形態では、立位にＦＰＤ撮影装置８が、臥位にＦＰＤ撮影装置９が対応付けられている。 The photographing device determination table 524 stores the types of photographing devices corresponding to the standing position and the prone position. In the present embodiment, the FPD photographing apparatus 8 is associated with the standing position, and the FPD photographing apparatus 9 is associated with the lying position.
　その他の放射線画像撮影システム２００の構成については、第１の実施の形態で説明したものと同様であるので説明を省略する。 Other configurations of the radiographic image capturing system 200 are the same as those described in the first embodiment, and a description thereof will be omitted.
　次に、第２の実施の形態における動作について説明する。
　放射線画像撮影システム２００の動作は、第１の実施形態で説明したものと同様である。即ち、コンソール５では、図４に示す放射線照射制御処理が実行される。第２の実施の形態における放射線照射制御処理は、処理中で照射条件テーブル５２３や撮影装置決定テーブル５２４が参照されるほかは、第１の実施の形態と同様であるので説明を省略する。
　放射線照射制御処理を実行することによって、コンソール５は、シンチレータ種の異なるＦＰＤ撮影装置８、９を備えた放射線撮影システム２００において、撮影に使用する撮影装置が変更となった場合に、撮影室Ｒ１内における撮影装置変更操作に応じて放射線発生装置３の放射線照射条件を変更先の撮影装置に応じた放射線照射条件に変更する。 Next, the operation in the second embodiment will be described.
The operation of the radiographic image capturing system 200 is the same as that described in the first embodiment. That is, the console 5 executes the radiation irradiation control process shown in FIG. The radiation irradiation control process in the second embodiment is the same as that of the first embodiment except that the irradiation condition table 523 and the imaging apparatus determination table 524 are referred to during the process, and thus the description thereof is omitted.
By executing the radiation irradiation control process, the console 5 can change the imaging room R1 when the imaging apparatus used for imaging is changed in the radiation imaging system 200 including the FPD imaging apparatuses 8 and 9 having different scintillator types. The radiation irradiation condition of the radiation generating device 3 is changed to the radiation irradiation condition according to the change-destination imaging apparatus in accordance with the imaging apparatus changing operation.
　撮影装置の種類の変更の指示を入力するための操作手段としては、第１の実施の形態と同様、ＦＰＤカセッテの起動スイッチや電源スイッチ、又は撮影装置に備えられた簡易操作部が用いられる。 As the operation means for inputting an instruction to change the type of the photographing apparatus, as in the first embodiment, an FPD cassette start switch, a power switch, or a simple operation unit provided in the photographing apparatus is used.
　以上のように、第２の実施の形態においては、シンチレータ種の異なるＦＰＤ撮影装置を備えた放射線画像撮影システム２００において、コンソール５での撮影装置の選択後に、撮影室Ｒ１内に設けられた、撮影装置の種類の変更をコンソール５に通知する指示を入力するための操作手段、例えば、ＦＰＤカセッテの起動スイッチ、電源スイッチ、又は撮影装置に備えられた簡易操作部等が操作されると、コンソール５は、操作手段から撮影装置の種類の変更指示が入力されたことを検知して放射線発生装置３の放射線照射条件等を変更先の撮影装置に応じた放射線照射条件等に変更する。従って、撮影実施者は、撮影室Ｒ１において、例えば、患者が車椅子である、撮影装置が故障している等の理由により撮影装置の種類を変更しなければならなくなった場合においても、従来のように撮影室Ｒ１から出てコンソール５を操作して放射線照射条件を手動で変更する必要がなく、撮影室Ｒ１内で容易に放射線照射条件の変更操作を行うことが可能となる。その結果、撮影装置の変更が生じてもスムーズに撮影を進行させることが可能となり、撮影効率を向上させることが可能となる。 As described above, in the second embodiment, in the radiographic image capturing system 200 including the FPD image capturing devices of different scintillator types, provided in the image capturing room R1 after selecting the image capturing device on the console 5. When an operation means for inputting an instruction for notifying the console 5 of a change in the type of the imaging device, such as an FPD cassette activation switch, a power switch, or a simple operation unit provided in the imaging device, is operated. 5 detects that an instruction to change the type of the imaging apparatus is input from the operation means, and changes the radiation irradiation condition or the like of the radiation generation apparatus 3 to the radiation irradiation condition or the like according to the imaging apparatus of the change destination. Therefore, even when the photographer has to change the type of the photographing apparatus in the photographing room R1, for example, because the patient is a wheelchair or the photographing apparatus is out of order. Thus, it is not necessary to change the radiation irradiation condition manually by leaving the imaging room R1 and operating the console 5 to change the radiation irradiation condition easily in the imaging room R1. As a result, even if the photographing apparatus is changed, photographing can be performed smoothly, and photographing efficiency can be improved.
　なお、上述した第１及び第２の実施の形態における記述は、本発明に係る好適な放射線画像撮影システムの一例であり、これに限定されるものではない。
　例えば、上記第１及び第２の実施の形態においては、最も好ましい形態として撮影装置を２台として説明したが、３台以上備える構成としてもよい。この場合、撮影装置に備えた簡易操作部からどの撮影装置に変更するか（変更先）を入力可能な構成とし、コンソール５に変更先となる撮影装置を通知することとすれば、コンソール５において、変更先の撮影装置に対応する放射線照射条件を放射線発生装置３に設定することが可能となる。 The description in the first and second embodiments described above is an example of a suitable radiographic imaging system according to the present invention, and the present invention is not limited to this.
For example, in the first and second embodiments described above, two imaging devices have been described as the most preferable mode, but a configuration including three or more imaging devices may be employed. In this case, if the simple operation unit provided in the photographing apparatus is configured to be able to input which photographing apparatus is to be changed (change destination) and the console 5 is notified of the photographing apparatus to be changed, the console 5 Thus, it becomes possible to set the radiation generation condition corresponding to the imaging apparatus to be changed in the radiation generation apparatus 3.
　また、上記実施の形態においては、操作手段として、ＦＰＤカセッテの起動スイッチや電源スイッチ、撮影装置に備えられた簡易操作部等を使用することとして説明したが、撮影室Ｒ１内に備えられているのであれば、撮影装置とは別体の操作装置であってもよい。 In the above-described embodiment, the FPD cassette activation switch, power switch, simple operation unit provided in the photographing apparatus, and the like are used as the operation means. However, the operation unit is provided in the photographing room R1. In this case, it may be a separate operating device from the photographing device.
　また、ＦＰＤは、上記に挙げたシンチレータ種のほか、直接型と間接型の違いによっても感度は異なる。これらの種類が互いに異なるＦＰＤ撮影装置が混在するシステムにおいても、本発明を適用することができる。 In addition to the scintillator types listed above, FPDs have different sensitivities depending on the direct type and indirect type. The present invention can also be applied to a system in which different types of FPD photographing apparatuses are mixed.
　その他、放射線画像撮影システムを構成する各装置の細部構成及び細部動作に関しても、本発明の趣旨を逸脱することのない範囲で適宜変更可能である。 In addition, the detailed configuration and detailed operation of each device constituting the radiographic imaging system can be changed as appropriate without departing from the spirit of the present invention.
