PROBLEM TO BE SOLVED: To provide good images by making it possible to flexibly pick up images of desired parts, and correcting deviations caused by the deflection of a support member. SOLUTION: Magnetism generated from a transmitter 8 is received by receivers 9a, 9b, and its input signals are inputted to the position calculating part 121 of an image processing part 12. The position calculating part 121 calculates the actual positions of an X-ray generating part 1 and an X-ray detecting part 2 from the input signals and outputs the actual positions to a deviation calculating part 124. The deviation calculating part 124 is given data about the proper positions of the X-ray generating part 1 and the X-ray detecting part 2 from a control part 10 and calculates deviations from the actual positions to output the deviations to a reconfiguring part 123. Since the reconfiguring part 123, when constituting a three-dimensional taken image on the basis of X-ray detection data obtained from the X-ray detecting part 2, reconfigures the taken image while performing corrections allowing for the deviations, good images can be obtained. Because of a C-arm type, images of the desired parts can be picked up flexibly.
