Abstract
An X-ray CT apparatus according to an embodiment includes a photon counting detector that outputs a signal that enables measurement of an energy value of an X-ray photon incident thereon, and processing circuitry configured to determine a time to make a transition from a prescan to a main scan by estimating, from projection data, an amount of a contrast agent present on an X-ray path including a monitored region set for a subject in the prescan, the projection data having been generated by detection of X-rays by the photon counting detector, the X-rays having been transmitted through the monitored region.
