Abstract
A photon-counting X-ray computed tomography (CT) apparatus according to an embodiment includes an X-ray tube, a detector, a photon counting circuitry, a correcting circuitry, and a calculating circuitry. The X-ray tube irradiates a subject with X-rays. The detector includes a plurality of detection elements that detect photons of X-rays incident on the detection elements. The photon counting circuitry counts the count of X-ray photons for each energy bin set in an X-ray energy distribution, for each position of the X-ray tube, and for each of the detection elements. The correcting circuitry corrects the count of the X-ray photons counted by the photon counting circuitry, based on a detection characteristic, of the detection elements. The calculating circuitry calculates the reliability of a pixel in a reconstruction image, based on the correction.
