Photon counting ct apparatus

Abstract

According to one embodiment, a photon counting computed tomography (CT) apparatus includes an X-ray generator configured to generate an X-ray, an X-ray detector of a photon counting type configured to detect the X-ray that has passed through a subject, and processing circuitry configured to acquire count data by counting the number of X-ray photons for each energy band, based on a detection result of the X-ray by the X-ray detector, set a first condition and a second condition as band settings that are settings of the energy band, and execute successively a first scan that is performed under the first condition, and a second scan that is performed under the second condition, on the subject placed on a tabletop.

Dependencies are inferred from the claim text.
