<P>PROBLEM TO BE SOLVED: To provide an X-ray CT apparatus allowing change of an optical magnification ratio and a photographic range. <P>SOLUTION: This X-ray CT apparatus includes: an X-ray tube 121 irradiating a subject P with X-rays; a first detector 131a detecting the X-rays transmitted through the subject; a second detector 131b detecting the X-rays transmitted through the subject, and having a curvature different from the first detector 131a; a drive means provided in the X-ray tube 121; and an operation part 170 inputting a changeover signal for changing over the first detector 131a and the second detector 131b. The X-ray tube 121 can be moved between the focus position of the first detector 131a and the focus position of the second detector 131b by the drive means based on the changeover signal from the operation part 170. <P>COPYRIGHT: (C)2013,JPO&INPIT |
