Abstract
Description
従来のX線透視装置は、図10(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54とを有するとともに、X線管53及びX線検出器54を対向保持したまま天板51の長手方向に沿って移動させる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10(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X線検出器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、X線検出器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。
前記被検体の乗降に適合した前記天板の位置姿勢状態及び前記X線照射手段の位置を乗降適合状態として予め記憶する乗降適合状態記憶手段と、前記天板の位置姿勢状態及び前記X線照射手段の位置が前記乗降適合状態記憶手段に記憶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線照射手段駆動手段を制御する乗降適合状態制御手段と、当該乗降適合状態制御手段への指示を入力する入力手段とを備えたことを特徴とする。
以下、乗降適合状態記憶メモリ21および乗降適合状態制御部22について、図2の例を元に、より具体的に説明する。
2 …天板駆動部
3 …X線撮像機構(X線撮像手段)
4 …X線管
5 …X線検出器
6 …X線撮像系移動部
11 …操作卓(乗降適合状態指定手段)
21 …乗降適合状態制御メモリ(乗降適合状態登録手段)
22 …乗降適合状態制御部
M …被検体
