PROBLEM TO BE SOLVED: To provide an X-ray diagnostic apparatus capable of moving an X-ray detector in a desired direction so as not to block a visual field of an operator during a procedure under fluoroscopy.SOLUTION: An X-ray diagnostic apparatus 100 includes an arm 12 for supporting an X-ray irradiation direction of an X-ray tube 101 for irradiating an X-ray and a detector 111 for detecting the X-ray so that they are opposed to each other with a subject P in between, an X-ray diaphragm 102 for narrowing the X-ray to an irradiation range of a predetermined size, an X-ray diaphragm control part 165 for controlling the X-ray diaphragm, a movement control part 166 for receiving the irradiation range from the X-ray diaphragm control part 165, and calculating an amount of movement of the detector 111, and a detector moving part 113 for moving the detector 111 in a parallel direction relative to the detection surface based on the amount of movement calculated by the movement control part 166.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】X線透視下での手技中に、オペレータの視野を遮ることがないようにX線検出器を所望の方向へ移動することが可能なX線診断装置を提供する。【解決手段】X線診断装置100は、X線を照射するX線管101のX線照射方向と、X線を検出する検出器111とが被検体Pを挟んで互いに対向するように支持するアーム12と、X線を所定の大きさの照射範囲に絞るX線絞り102と、X線絞りの制御を行うX線絞り制御部165と、照射範囲をX線絞り制御部165から受け付けて、検出器111の移動量を算出する移動制御部166と、移動制御部166が算出した移動量に基づいて、検出器111を検出面に対して平行方向に移動させる検出器移動部113を具備する。【選択図】図1
