Abstract
A controller controls 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 supported by the stand, an X-ray tube supported at one end of the C-arm, and an X-ray detector supported at the other end of the C-arm rotatably about a shooting axis passing through the X-ray focus of the X-ray tube and the center of the detection surface. The controller includes the steps of moving the X-ray tube and the X-ray detector linearly by controlling the rotation of the floor-mounted rotary arm and the rotation of the stand, and maintaining the orientation of the image in a display screen by controlling the axial rotation of the X-ray detector in synchronization with the rotation of the floor-mounted rotary arm and the rotation of the stand.
