【発明の属する技術分野】
この発明は、例えばX線透視装置などのように、天板に乗せられた被検体のX線撮影を行う医用X線診断装置に係り、特に被検体を天板に楽に乗り降りさせられるようにするための技術に関する。
【0002】
【従来の技術】
図9は、病院等の医療施設で使われている従来のX線透視装置の透視台側の基本構成を示す模式図である。従来のX線透視装置は、図9(a)に示すように、被検体(患者)Mが載置されるとともに、位置および姿勢を変化させられる天板51と、天板51を挟んで対向するX線管53及びX線検出器であるイメージインテンシファイア(I・I管)54を有するとともに天板51に設置されているX線撮像機構52とを透視台側に備えている。そして、このX線透視装置は、図9(b)に示すように、天板51の位置・姿勢を変化させることにより天板51を起倒動などさせて、X線管53から被検体Mに照射するX線によって生じる被検体Mの透過X線像がI・I管54によって検出されてX線検出データとして後段に出力される一方、I・I管54から出力されたX線検出データに基づきX線透視画像が作成表示される構成となっている。
【0003】
【発明が解決しようとする課題】
しかしながら、上記の従来のX線透視装置の場合、天板51に被検体を乗り降りさせるのが楽でないという問題がある。被検体を天板51に楽に乗り降りさせられないと、X線透視がスムーズに進められない。
【0004】
具体的には、被検体Mが例えば大人の健常者である場合は、天板51やX線撮像機構52の状態が乗り降りに少々適当でなくても、さして不自由なこともないが、被検体Mが老人や怪我人などの要介護者や小児などの場合は、天板51やX線撮像機構52の状態が乗り降りに不適当であれば、天板51の乗り降りは難しくなる。つまり、要介護者や小児は高さが適当でない天板51に自分で乗り降りするのは無理だし、天板51に設置されているX線撮像機構52は、要介護者や小児の乗り降りを手助けしようとする介護者の作業の邪魔になるのである。
【0005】
勿論、天板51やX線撮像機構52の状態が天板51の乗り降りに不適当である場合、オペレータが操作卓(図示省略)からマニュアル操作(手動操作)で天板51の高さやX線撮像機構52の位置などを調整することになるが、この調整がオペレータにとっては楽なことではない。起倒動などの為に天板51の位置や姿勢を大きく変化させるX線透視装置の場合、被検体Mを天板51に乗り降りさせる場合の天板51やX線撮像機構52の状態が一定しておらずマチマチで、天板51やX線撮像機構52の状態を次の被検体Mの乗り降りにちょうど適合する状態に手動操作で変更する作業は、かなり手間がかかり、オペレータにとっては相当の負担なのである。
【0006】
この発明は、上記の事情に鑑み、被検体を天板に楽に乗り降りさせることができる医用X線診断装置を提供することを課題とする。
【0007】
【課題を解決するための手段】
前記課題を解決するために、請求項1の発明に係る医用X線診断装置は、被検体が載置される天板と、前記天板の位置とその姿勢の少なくとも一方を変化させて天板の位置姿勢状態を変化させる天板駆動手段と、前記天板を挟んで対向するX線照射手段およびX線検出手段を有して天板またはその近傍に配設されているX線撮像手段と、前記X線撮像手段の位置を変化させるX線撮像系移動手段とを備えた医用X線診断装置において、被検体の乗降に適合した前記天板の位置姿勢状態と前記X線撮像手段の位置とを乗降適合状態として予め登録する乗降適合状態登録手段と、前記天板の位置姿勢状態と前記X線撮像手段の位置とを、前記乗降適合状態登録手段に登録された乗降適合状態に一致するように前記天板駆動手段および前記X線撮像系移動手段を制御する乗降適合状態設定手段とを備え、前記乗降適合状態登録手段は、被検体の状況に応じた複数の乗降適合状態を登録し、前記乗降適合状態登録手段に登録されている複数の乗降適合状態の中の特定の乗降適合状態を指定する乗降適合状態指定手段を備え、前記乗降適合状態設定手段は前記乗降適合状態指定手段からの指定された乗降適合状態に従って前記制御を実行することを特徴とするものである。
【0008】
また、請求項2の発明は、請求項1に記載の医用X線診断装置において、前記X線撮像手段は前記天板に設置され、前記X線撮像系移動手段は前記X線撮像手段の位置を天板の長手方向に変化させるように構成されていることを特徴とするものである。
【0010】
〔作用〕
次に、この発明の医用X線診断装置の作用を説明する。
請求項1に記載の医用X線診断装置は、被検体を天板に乗り降りさせる場合、天板の位置とその姿勢の少なくとも一方を変化させて天板の位置姿勢状態を変化させる天板駆動手段およびX線撮像手段の位置を変化させるX線撮像系移動手段を乗降適合状態設定手段により制御し、天板の位置姿勢状態とX線撮像手段の位置とを、乗降適合状態登録手段に登録された乗降適合状態に一致させ、乗降適合状態に設定しておいてから、天板に被検体を乗り降りさせる。天板の位置姿勢状態もX線撮像手段の位置も乗降適合状態になっているので、被検体を天板に乗り降りさせるのは楽である。
【0011】
すなわち、請求項1に記載の医用X線診断装置によれば、オペレータによる手動調整操作によらずに、乗降適合状態設定手段により、天板の位置姿勢状態とX線撮像手段の位置とを、乗降適合状態登録手段に登録された乗降適合状態に一致させるので、天板の位置姿勢状態もX線撮像手段の位置も全て自動的に乗降適合状態に設定されるのである。
【0012】
また、請求項2に記載の医用X線診断装置によれば、乗降適合状態設定手段による制御作動の際、X線撮像手段の位置が、X線撮像系移動手段によって天板の長手方向に移動して被検体の乗り降りを楽にさせる乗降適合状態へ自動的に設定される。
【0013】
また、請求項1に記載の医用X線診断装置によれば、被検体を天板に乗り降りさせる際、オペレータが乗降適合状態指定手段によって乗降適合状態登録手段に登録されている複数の乗降適合状態の中の適当な乗降適合状態を指定すると、乗降適合状態設定手段は、天板の位置姿勢状態とX線撮像手段の位置とを、指定された乗降適合状態に一致させる。即ち、天板の位置姿勢状態もX線撮像手段の位置も指定された適切な乗降適合状態に自動的に設定されるのである。
【0014】
【発明の実施の形態】
続いて、この発明の医用X線診断装置の一実施例としてのX線透視装置を図面を参照しながら説明する。図1は実施例に係るX線透視装置の全体構成を示すブロック図である。
【0015】
実施例のX線透視装置は、図1に示すように、被検体Mが載置される天板1と、天板1の位置および姿勢を変化させて天板1の位置姿勢状態を変化させる天板駆動部2と、天板1を挟んで対向するX線管4およびX線検出器5を有していて天板1に設置されているX線撮像機構3とを透視台側に備えている。そして、このX線透視装置は、天板1の位置・姿勢を変化させることにより天板1を起倒動などさせて、X線管4から天板1の上の被検体Mに照射するX線によって生じる被検体Mの透過X線像がX線検出器5によって検出されてX線検出データとして後段へ出力されるとともに、X線検出器5から出力されたX線検出データに基づきX線透視画像が作成表示されるよう構成されている。以下、実施例のX線透視装置の各部構成を具体的に説明する。
【0016】
この実施例装置は、例えば、天板1の位置・姿勢を変化させて天板1の位置姿勢状態を変化させるように構成されている。具体的には、天板駆動部2は、矢印RAで示すように天板1の長手(前後)方向に天板1を往復直線移動が可能であるとともに、矢印RBで示すように天板1の幅(左右)方向に天板1を往復直線移動が可能であるのに加え、矢印RCで示すように天板1の垂直(上下)方向に天板1を往復直線移動が可能であるだけでなく、さらに矢印RDで示すように天板1全体を往復回転移動が可能であるように構成されている。つまり矢印RA〜RDで示すような天板1の移動を組み合わせて実行し天板1の位置および姿勢を変化させることにより、図2に示すように、天板51を起倒動などさせられる構成となっているのである。つまり、矢印RA〜RDで示す移動が天板1の位置・姿勢を変化させるファクターとなっているのである。なお、上述した矢印RA〜RDで示す移動を行わせる機構としては、ラックとピニオンを用いた移動機構やボールネジを用いた移動機構などによって実現可能である。
【0017】
より具体的に説明すれば、図1および図2に示すように、天板駆動部2には、床に垂直に立設されている支持柱2aを上下方向(矢印RCの方向)に昇降可能な昇降ブロック2bが配設されている。この昇降ブロック2bには、天板1の幅方向(矢印RBの方向)に延びる軸を回転軸としてこの軸周りに回動可能な回動アーム2cと、天板1を前後(矢印RAの方向)・左右(矢印RBの方向)に直線移動させる機構(図示省略)とが配設されている。天板1の下側は、回動アーム2cにより支持されている。このように、天板駆動部2は、昇降ブロック2bの昇降動作や回動アーム2cの回転動作や前後・左右の直線移動用の機構による直線移動動作により、矢印RA〜RDで示す天板1の移動が行われる構成となっている。なお、矢印RA〜RDで示す天板1の移動を行う天板駆動部2のコントロールは天板制御部7によって実行される。
【0018】
一方、天板1に設置されているX線撮像機構3は、もちろん矢印RA〜RDで示すような天板1の移動に伴って天板1と一体的に移動するだけでなく、矢印REで示すようにX線撮像系移動部6により天板1の長手方向に往復直線移動させられ、X線撮像機構3の位置が天板の長手方向に変化させられるよう構成されている。矢印REで示す移動がX線撮像機構3の位置を変化させるファクターとなっているのである。すなわち、図3に示すように、X線撮像機構3は、X線撮像系移動部6によって、実線で示す前端位置から一点鎖線で示す後端位置の間を変化することができるよう構成されているのである。上述した矢印REで示すような直線移動を行う機構としては、やはりラックとピニオンを用いた移動機構やボールネジを用いた移動機構などによって実現可能である。
【0019】
より具体的に説明すれば、図1および図3に示すように、X線撮像系移動部6は、X線管4とX線検出器5とが対向状態で取り付けられているコ字状のサポート支柱6aと、天板1の裏側に天板1と一体化するように配設されているとともに両脇の側面が開口している枠状プレート6bとを備えており、枠状プレート6bの内部にX線検出器5を収容した状態でサポート支柱6aが天板1の長手(前後)方向に直線移動してX線撮像機構3の位置が天板1の長手方向に変化する構成となっている。なお、矢印REで示すX線撮像機構3の移動を行うX線撮像系移動部6のコントロールは撮像系位置制御部8によって実行される。
【0020】
一方、X線管4は前面側にX線の照射範囲を規定するコリメータ4aを備えており、また実施例装置の場合、X線管4も左右の首振り微動や仰俯方向の首振り微動あるいは上下方向の直進微動も行える構成になっている。
【0021】
他方、X線検出器5は、X線検出素子が縦横に多数のアレイ配列されたいわゆるフラットパネル型X線センサ(FPD)であり、I・I管に比べると薄型・軽量となっている。実施例の装置の場合、X線検出器5の方も天板1の長手方向の直線微動を行うことによりX線検出面積の不足をカバーするような動作も可能な構成となっている。
【0022】
X線透視実行の際は、X線管4は、高電圧発生器などを含む照射制御部9のコントロールにより、管電圧・管電流等の設定照射条件に合致したX線を被検体Mに照射するよう構成されている。なお、上記の天板制御部7や撮像系位置制御部8あるいは照射制御部9によるコントロールは、操作卓11などの入力操作に伴って撮影制御部10から送出される指令信号に従って行われる。
【0023】
また、X線検出器5の後段には、検出器5から出力されるX線検出データを収集し、画像処理部13へ送り出す信号収集部12が配設されている。また、画像処理部13には、信号収集部12からのX線検出データをディジタル信号に変換するAD変換部14と、ディジタル化されたX線検出データを記憶する検出データメモリ15と、検出データメモリ15に記憶されたX線検出データにエッジ強調やフィルタリングなどの必要な画像処理を施すことによりX線画像を作成するデータ処理部16と、画像処理で得られたX線透視画像を記憶するX線画像メモリ17とが配設されている。X線透視の場合、通常、撮影中、X線画像メモリ17に格納されたX線画像は次々と更新され続けることになる。
【0024】
さらに、実施例のX線透視装置では、X線画像メモリ17に記憶されたX線透視画像を表示する画像表示モニタ18や、X線透視中、操作卓11や入力操作による指令等に従って、X線画像メモリ17に記憶されるX線透視画像をフィルムなどのシートに焼き付けてX線写真として出力する画像焼付け記録部19、および、X線透視画像を記録して保存する画像保存メモリ20も設けられている。
【0025】
そして、さらに実施例のX線透視装置は、天板1に対する被検体Mの乗降に適合した天板1の位置および姿勢(天板1の位置姿勢状態)とX線撮像機構3の位置とを乗降適合状態として登録している乗降適合状態登録メモリ21と、天板1の位置および姿勢(天板1の位置姿勢状態)とX線撮像機構3の位置とを乗降適合状態登録メモリ21に登録された乗降適合状態に一致させるように天板駆動部2およびX線撮像系移動部6を制御する乗降適合状態設定部22とを備えている点が、構成上の顕著な特徴となっている。以下、乗降適合状態登録メモリ21および乗降適合状態設定部22について、より具体的に説明する。
【0026】
乗降適合状態登録メモリ21は、複数の乗降適合状態を記憶しているとともに、操作卓11によって乗降適合状態登録メモリ21に登録されている複数の乗降適合状態の中の特定の乗降適合状態を指定することができるようにも構成されている。
【0027】
つまり、被検体Mが例えば大人の健常者である場合は、天板1やX線撮像機構3の状態が乗り降りに少々適当でなくても、さして不自由なこともないが、特に被検体Mが老人や怪我人などの要介護者や小児などの場合には、天板1やX線撮像機構3の状態には乗り降りに適した乗降適合状態がある。つまり、普通、乗降適合状態は、一つではなくて、被検体Mの状況に応じた幾つもの乗降適合状態があるのである。
【0028】
被検体Mが例えば小児や足の負傷者である場合は、例えば、図4に示すように、天板1が水平姿勢で高さが低い位置にあって、かつX線撮像機構3が後端側(足側)に寄って位置する状態が乗降適合状態(以下、「乗降適合状態A」と記す)となる。乗降適合状態Aに設定されていれば、小児や足の負傷者は、天板1の中央側(天板1の前端側(頭側)と天板1の後端側(足側)との中央付近)に腰を下すようにして天板1に乗ることができ、小児や足の負傷者でも、X線撮像機構3に邪魔されずに、被検体Mを天板1に楽に乗り降りさせられる。
【0029】
被検体Mが例えば寝たきりの要介護者などの場合は、例えば、図5に示すように、天板1を水平姿勢にするとともに、天板1の高さをこの天板1に横付けされる被検体搬送用ストレッチャー等の移動台車23の高さ位置と同じにし、かつ、X線撮像機構3を天板1の前端側(頭側)に寄せた位置にする状態を乗降適合状態(以下、「乗降適合状態B」と記す)としている。乗降適合状態Bであれば、例えば、移動台車23を天板1の側方に隣接するように横付けし、要介護者でも、X線撮像機構3に邪魔されることなく、天板1の両脇側(両側方側)から複数人の介護者によって手助けされながら、移動台車23の被検体Mを天板1へ楽に乗せられるし、逆に天板1の被検体Mを移動台車23へ楽に降ろせる。
【0030】
また、被検体Mが健常者であって透視内容によっては、天板1が垂直に起立した姿勢でX線撮像機構3が前端側(頭側)に位置する状態が乗降適合状態(以下、「乗降適合状態C」と記す)となる。乗降適合状態Cであれば、X線撮像機構3に邪魔されずに、被検体Mを楽に天板1を乗り降りさせることができる。
【0031】
勿論、乗降適合状態設定部22により設定される乗降適合状態は、上記の乗降適合状態A〜Cに限られるのものではなく、乗降適合状態A〜C以外の乗降適合状態も登録することができ、その状態に設定することもできる。なお、この乗降適合状態A〜C以外の乗降適合状態としては、例えば、X線撮像機構3が真ん中にあって天板1の長手方向両側に介護者が立ち易い乗降適合状態や、図5において天板1の高さが低い他は同じ状態であって車椅子に乗った被検体Mに好適である乗降適合状態などがあり、天板1の高さ(位置)および姿勢(水平、起立、傾斜姿勢など)とX線撮像機構3の位置との組み合わせにより種々の状態が挙げられる。
【0032】
さらに、実施例装置の場合、図6に示すように、操作卓11による入力操作により、操作卓11の液晶表示部11aの画面に、乗降適合状態登録メモリ21に登録されている乗降適合状態A〜Cを呼び出して乗降適合状態A〜Cのリストを表示させられるとともに、オペレータが乗降適合状態A〜Cの中の特定のものをタッチして入力した後、続いて画面の中の実行スイッチ11bをタッチすれば、乗降適合状態設定部22により天板制御部7および撮像系位置制御部8経由で天板駆動部2およびX線撮像系移動部6が制御され、天板1の位置および姿勢とX線撮像機構3の位置とが、上述の指定された乗降適合状態に一致させられて、上述の指定された乗降適合状態に自動的に設定される。なお、図6に示す11cは、各種の入力スイッチが設けられた入力パネルである。
【0033】
続いて、以上に述べた実施例の装置によってX線透視を実行する際の進行プロセスを被検体Mの天板1の乗り降りを中心に図面を参照しながら説明する。図7は実施例のX線透視装置によるX線透視の進行プロセスを示すフローチャートである。
【0034】
〔ステップS1〕先ず、オペレータは、図6に示すように、操作卓11の液晶表示部11aの画面に、乗降適合状態登録メモリ21に登録されている複数の乗降適合状態A〜Cのリストを呼び出して表示させる。
【0035】
〔ステップS2〕オペレータは、乗降適合状態A〜Cの中からX線透視対象の被検体(例えば、小児)Mにマッチした乗降適合状態Aをタッチ(タッチ画面入力)して指定した後、実行スイッチ11bをタッチ(タッチ画面入力)する。
【0036】
〔ステップS3〕乗降適合状態設定部22が作動し、天板1の位置および姿勢とX線撮像機構3の位置とが指定した乗降適合状態に一致させられ、図4に示すように、乗降適合状態Aが自動的に設定される。
【0037】
〔ステップS4〕乗降適合状態Aに設定された天板1に被検体Mを乗せる。
【0038】
〔ステップS5〕天板1に乗せられた被検体MのX線透視を実行する。
【0039】
〔ステップS6〕X線透視が済むと、オペレータは操作卓11の液晶表示部11aの画面に乗降適合状態A〜Cのリストを再び呼び出して表示する。
【0040】
〔ステップS7〕オペレータは乗降適合状態A〜Cの中の乗降適合状態Aを再度タッチして指定した後、実行スイッチをタッチする。
【0041】
〔ステップS8〕乗降適合状態設定部22がやはり作動し、図4に示すように、乗降適合状態Aがもう一度、自動的に設定される。
【0042】
〔ステップS9〕乗降適合状態Aに設定された天板1から被検体Mを降ろせば、X線透視は全て完了することとなる。
【0043】
以上に詳述したように、実施例のX線透視装置によれば、オペレータによる手動調整操作によらずとも、操作卓11により乗降適合状態登録メモリ21に登録されている乗降適合状態A〜Cの中の適当な状態を画面タッチ操作で指定すれば、乗降適合状態設定部22が作動して、天板1の位置および姿勢とX線撮像機構3の位置とが指定した乗降適合状態に一致させられて、指定した適切な乗降適合状態が自動的に設定されるので、被検体Mを天板1に非常に楽に乗り降りさせることが出来、X線透視はスムーズに進行する。
【0044】
この発明は、上記実施の形態に限られることはなく、下記のように変形実施することができる。
【0045】

【0056】
また、請求項2の発明の医用X線診断装置によれば、乗降適合状態設定手段による制御作動が行われる際、X線撮像系移動手段によってX線撮像手段の位置が天板の長手方向に移動させられて被検体の乗り降りを楽にさせる乗降適合状態に自動的に設定される。

FIG. 9 is a schematic diagram showing a basic configuration on the fluoroscopic table side of a conventional X-ray fluoroscopic apparatus used in a medical facility such as a hospital. As shown in FIG. 9 (a), the conventional X-ray fluoroscopic apparatus is opposed to a top plate 51 on which a subject (patient) M is placed and the position and posture of the top plate 51 can be changed. An X-ray tube 53 and an image intensifier (I / I tube) 54 as an X-ray detector, and an X-ray imaging mechanism 52 installed on the top plate 51 are provided on the fluoroscopic table side. Then, as shown in FIG. 9B, the X-ray fluoroscopic apparatus moves the top plate 51 up and down by changing the position / posture of the top plate 51, so that the subject M is removed from the X-ray tube 53. X-ray detection data output from the I / I tube 54, while the transmission X-ray image of the subject M generated by the X-rays irradiated on the X-ray is detected by the I / I tube 54 and output as X-ray detection data to the subsequent stage. X-ray fluoroscopic images are created and displayed based on the above.
[0003]
[Problems to be solved by the invention]
However, in the case of the conventional X-ray fluoroscopic apparatus, there is a problem that it is not easy to get on and off the subject on the top plate 51. X-ray fluoroscopy cannot proceed smoothly unless the subject can easily get on and off the top board 51.
[0004]
Specifically, when the subject M is, for example, an adult healthy person, the state of the top 51 or the X-ray imaging mechanism 52 is not suitable for getting on and off. When the sample M is a care recipient such as an elderly person or an injured person or a child, if the state of the top 51 or the X-ray imaging mechanism 52 is inappropriate for getting on and off, it is difficult to get on and off the top 51. In other words, it is impossible for a care recipient or child to get on and off the top board 51 whose height is not appropriate, and the X-ray imaging mechanism 52 installed on the top board 51 helps the care recipient or child to get on and off. It interferes with the work of the caregiver who is trying.
[0005]
Of course, when the state of the top plate 51 and the X-ray imaging mechanism 52 is inappropriate for getting on and off the top plate 51, the operator manually operates (manually operates) the height of the top plate 51 or X-rays from the console (not shown). The position of the imaging mechanism 52 and the like are adjusted, but this adjustment is not easy for the operator. In the case of an X-ray fluoroscopy device that greatly changes the position and orientation of the top 51 due to tilting and the like, the state of the top 51 and the X-ray imaging mechanism 52 when the subject M gets on and off the top 51 is constant. The work of manually changing the state of the top 51 or the X-ray imaging mechanism 52 to a state that just fits the next boarding / exiting of the subject M takes a lot of time and is quite troublesome for the operator. It is a burden.
[0006]
In view of the above circumstances, an object of the present invention is to provide a medical X-ray diagnostic apparatus capable of easily getting on and off a subject on a top board.
[0007]

Since the position / posture state of the top board and the position of the X-ray imaging means are both in the boarding / exiting state, it is easy to get on and off the subject.
[0011]
That is, according to the medical X-ray diagnostic apparatus according to claim 1, the position / posture state of the top board and the position of the X-ray imaging means are determined by the boarding / adapting state setting means without using the manual adjustment operation by the operator. Since it matches with the boarding / alighting state registered in the boarding / alighting state registration means, the position / posture state of the top plate and the position of the X-ray imaging means are all automatically set to the boarding / aboarding state.
[0012]

The boarding / alighting state registration memory 21 registered as the boarding / alighting state, the position and orientation of the top board 1 (the position and orientation state of the top board 1), and the position of the X-ray imaging mechanism 3 are registered in the boarding / alighting state registration memory 21. It is a prominent feature of the configuration that it has a boarding / alighting state setting unit 22 that controls the top board driving unit 2 and the X-ray imaging system moving unit 6 so as to match the boarding / alighting state that has been made. . Hereinafter, the boarding / alighting state registration memory 21 and the boarding / alighting state setting unit 22 will be described more specifically.
[0026]
The boarding / alighting adaptation state registration memory 21 stores a plurality of boarding / alighting adaptation states, and designates a specific boarding / alighting adaptation state among the plurality of boarding / alighting adaptation states registered in the boarding / alighting adaptation state registration memory 21 by the console 11. It is also configured to be able to.
[0027]
That is, when the subject M is, for example, an adult healthy person, the state of the top board 1 and the X-ray imaging mechanism 3 is not suitable for getting on and off, and it is not inconvenient. However, in the case of a care recipient such as an elderly person or an injured person or a child, the state of the top board 1 or the X-ray imaging mechanism 3 has a boarding / exiting state suitable for getting on and off. In other words, the boarding / adapting state is not usually one, but there are several boarding / conforming states according to the condition of the subject M.
[0028]
When the subject M is, for example, a child or a leg injured person, for example, as shown in FIG. 4, the top plate 1 is in a horizontal position with a low height and the X-ray imaging mechanism 3 is at the rear end.

In the boarding / exiting state B, for example, the movable carriage 23 is placed side by side so as to be adjacent to the side of the top board 1, so that even a person requiring care does not interfere with the X-ray imaging mechanism 3. While being assisted by a plurality of caregivers from the side (both sides), the subject M of the movable carriage 23 can be easily placed on the top board 1, and conversely, the subject M of the top board 1 can be easily placed on the movable carriage 23. Can be lowered.
[0030]
In addition, depending on the fluoroscopic content of the subject M, the state in which the X-ray imaging mechanism 3 is positioned on the front end side (head side) with the top 1 standing upright is a boarding / exiting state (hereinafter, “ Boarding / alighting state C ”). In the boarding / alighting adaptation state C, the subject M can easily get on and off the top board 1 without being disturbed by the X-ray imaging mechanism 3.
[0031]
Of course, the boarding / alighting adaptation state set by the boarding / alighting adaptation state setting unit 22 is not limited to the above-mentioned boarding / alighting adaptation states A to C, and boarding / aboarding adaptation states other than the boarding / alighting adaptation states A to C can be registered. , It can also be set to that state. In addition, as the boarding / alighting adaptation states other than the boarding / alighting adaptation states A to C, for example, the boarding / alighting adaptation state in which the X-ray imaging mechanism 3 is in the middle and the caregiver can easily stand on both sides in the longitudinal direction of the top plate 1, or There is a boarding / adapting state suitable for the subject M on the wheelchair in the same state except that the height of the top plate 1 is low, and the height (position) and posture (horizontal, standing, tilting) of the top plate 1 There are various states depending on the combination of the posture and the like and the position of the X-ray imaging mechanism 3.
[0032]
Furthermore, in the case of the embodiment apparatus, as shown in FIG. 6, the boarding / alighting adaptation state A registered in the boarding / alighting adaptation state registration memory 21 on the screen of the liquid crystal display unit 11 a of the console 11 by an input operation by the console 11. ˜C is called to display a list of the boarding / alighting adaptation states A to C, and after an operator touches and inputs a specific one of the boarding / alighting adaptation states A to C, the execution switch 11b in the screen is subsequently displayed. Is touched, the top / bottom driving unit 2 and the X-ray imaging system moving unit 6 are controlled by the boarding / alight matching state setting unit 22 via the top panel control unit 7 and the imaging system position control unit 8, and the position and orientation of the top panel 1 are controlled.
