Abstract
A photon counting computed tomography (CT) apparatus actually measures corrective measurement values by radiating X-rays from an X-ray tube and counting X-ray photons in each of a plurality of energy bands in a vacant state in which no subject is arranged in an imaging range of the photon counting CT apparatus and/or in a state in which one or more types of corrective materials are arranged at a position through which X-rays radiated from the X-ray tube pass, and corrects measurement values in a material decomposition map based on the actually measured corrective measurement values.
