X-RAY COMPUTER TOMOGRAPHIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To allow CT image data in an integration mode to be output in a short period of time in an X-ray computer tomographic apparatus capable of executing a photon counting-mode.SOLUTION: An X-ray tube 13 generates X-ray photons. An X-ray detector 15 detects the X-ray photons generated by the X-ray tube 13. A data collection section 29 generates photon counting-mode raw data corresponding to respective ones of a plurality of energy regions of the X-ray photons generated by the X-ray tube 13 on an energy spectrum on the basis of output of the X-ray detector. An integration mode raw data generation section 43 adds the photon counting-mode raw data corresponding to the respective ones of the plurality of energy regions and generates integration mode data. A storage section 47 stores the integration mode data generated therein.
