Abstract:
    An X-ray computed tomography apparatus includes an X-ray tube which generates X-rays, an X-ray detector which detects X-rays transmitted through a subject to be examined, a mechanism which continuously rotates the X-ray tube and the X-ray detector, a storage unit which stores projection data detected by the X-ray detector, a read unit which reads out projection data sets of parts of a pair spaced apart from each other by 360 DEG from the storage unit, an index generating unit which generates a plurality of indices indicating movement of a heart on the basis of a difference between the projection data sets of the parts of the pair, a cardiac phase determination unit which determines a cardiac phase on the basis of the indices, and a reconstruction unit which reconstructs an image on the basis of a full projection data set corresponding to the determined cardiac phase.
