PROBLEM TO BE SOLVED: To solve the problem of a waiting time, that the handling by an operator becomes cumbersome since the waiting time is required until a sensor becomes stable, because the sensor becomes unstable at the time of switching when the sensor driving is switched for imaging a still image and for imaging an moving image.SOLUTION: An X-ray imaging apparatus includes: an X-ray generating unit an X-ray sensor unit which detects the X ray which has been generated by the X-ray generating unit and a control unit which controls the driving of the X-ray generating unit and the X-ray sensor unit. The control section performs alignment imaging in which the still image of a subject which is made the reference for performing the positioning of either one of the X-ray generating unit and the X-ray sensor unit is imaged, and main imaging in which imaging of a moving image of the subject is performed after the alignment imaging while making the same driving conditions of the X-ray sensor unit.COPYRIGHT: (C)2013,JPO&INPIT【課題】 静止画撮影と動画撮影とでセンサ駆動を切り替える場合、その切替え時にセンサが不安定になるため、センサが安定するまでの待機時間が必要であった。しかし、この待機時間は操作者の使い勝手を悪くする。【解決手段】 X線撮影装置は、X線発生部と、前記X線発生部で発生したX線を検出するX線センサ部と、前記X線発生部及び前記X線センサ部の駆動を制御する制御部とを有し、前記制御部は、X線発生部及びX線センサ部の少なくともいずれか一方の位置決めを行うための基準とする被写体の静止画を撮影する位置決め撮影と、該位置決め撮影の後に前記被写体の動画撮影を行う本撮影とを、X線センサ部の駆動条件を共通にして実行する。【選択図】 図1
