Abstract:
1. A method for controlling an X-ray diagnostic apparatus comprising a floor-mounted rotary arm mounted at one end on a floor rotatably about a substantially vertical rotation axis; a stand supported at the other end of the floor-mounted rotary arm rotatably about a substantially vertical rotation axis; a substantially C-shaped arm slidably supported by the stand; an X-ray tube supported at one end of the C arm; an X-ray detector supported at the other end of the C arm rotatably about a shooting axis passing through an X-ray focus of the X-ray tube and a center of the detection surface; a display screen and a controller, the method comprising the steps of: moving the X-ray tube and the X-ray detector linearly by controlling rotation of the floor-mounted rotary arm and rotation of the stand; and maintaining the orientation of an image in the display screen by controlling axial rotation of the X-ray detector in synchronization with the rotation of the floor-mounted rotary arm and the rotation of the stand.
