    • In an X-ray CT scan, a distance between an X-ray generator and a rotation center and/or a distance between a X-ray detector and the rotation center can be changed according to a magnification of an image. A rotary device has an X-ray generator and an X-ray detector opposing to each other, provided to interpose an object between them. A rotary mechanism rotates the rotary device around a rotary axis, and a movement mechanism moves the rotary axis or the object in a plane perpendicular to the rotary axis. The rotation center in a viewpoint of CT scan different from the rotary axis is always kept at a point in a region of interest in the object according to a motion synthesized from the rotation of the rotary device and the movement of the rotary axis or the object.
