ABSTRACT:
The present invention is intended to improve the quality of a three-dimensional display image, an MPR display image, or an MIP display image presented by an X-ray CT system that performs a conventional (axial) scan, a cine scan, or a helical scan. The X-ray CT system includes an image reconstruction unit or an image display unit. The image reconstruction unit or image display unit measures deviations of tomographic images in an x direction that is a horizontal direction and deviations thereof in a y direction that is a vertical direction according to the continuity in a z direction of an object that exhibits high CT numbers and that is visualized as a reference in the tomographic images; such as, a cradle, a head holder, the surface of a subject's body, or a bone. The image reconstruction unit or image display unit then compensates the deviations.
