X-RAY COMPUTED TOMOGRAPHY APPARATUS

摘要

PROBLEM TO BE SOLVED: To reduce a decline in an image resolution and the occurrence of artifacts due to shakes in rack rotation. SOLUTION: The X-ray computed tomography apparatus comprises: an X-ray tube 3 for generating X-rays which is supported so as to be freely rotated around a rotating shaft; a multi-channel type X-ray detector 8 rotated together with the X-ray tube and for detecting the X-rays transmitted through a subject; a reconstitution processing part 28 for reconstituting the image of the subject on the basis of the output of the X-ray detector; and a storage part 34 for storing information relating to the deviation of a center channel for each rotation angle of the X-ray tube in order to provide the information relating to the deviation of the center channel of the X-ray detector caused by the rotation deviation of the X-ray tube and the X-ray detector for the reconstitution processing part for each rotation angle of the X-ray tube.
