An X-ray CT system and an X-ray CT method in which an operator can bring an object as close as possible to an X-ray source at all times by preventing interference of the object with the X-ray source at the time of rotation without confirmation by an operator by rotating a rotary stage before CT photography. The object W mounted on the rotary stage (3) is photographed by means of an optical camera (6), and the shape and size of the object W and positional information thereof with respect to the rotational axis R are obtained by image processing using that data. Interference of the object W with the X-ray source (1) is monitored based on them, or the rotary stage (3) is positioned automatically to an noninterfering position closest to the X-ray source (1). |
