Zusammenfassung:PROBLEM TO BE SOLVED: To provide a photon counting mode while retaining a high counting capability of X-ray photons in an integral mode.SOLUTION: An X-ray tube 14 generates X rays. The radiation detector 16 repeatedly detects X rays generated from the X-ray tube 14 and transmitted through a subject, and repeatedly generates electric signals according to the energy of the repeatedly detected X rays. A support mechanism 12 supports the X-ray tube 14 and the radiation detector 16 in such a way as rotatable around a rotation axis. An integral DAS 26a collects electric signals in the integral mode. A photon counting DAS 26b collects electric signals in the photon counting mode.
