Abstract
In order to provide an X-ray CT apparatus and the like that can specify an optimal cardiac phase in a wide variety of cases, an X-ray CT apparatus collects X-ray information and electrocardiographic waveform databy performing cardiac scanning using an scanning unit(step S). Then, reconstructed images of a plurality of cardiac phases are created (step S), and a region-of-interest image is generated by extracting a region of interest for each of the reconstructed images of the plurality of cardiac phases (step S). Then, a variation distribution image is generated by calculating a variation for each region-of-interest image (step S). Then, the degree of harmony of each cardiac phase is calculated using the variation distribution image (step S). Then, an optimal cardiac phase is determined on the basis of at least the degree of harmony (step S).
