PROBLEM TO BE SOLVED: To control the temperature of a photoelectric conversion part in the vicinity of a predetermined temperature so as to execute temperature control for a SiPM to acquire stable output since the output of the SiPM, for example, is significantly dependent on the temperature.SOLUTION: An X-ray CT apparatus includes: a scintillator for converting an X-ray into light; a photoelectric conversion part for generating an electric signal based on the light converted by the scintillator; and temperature control means for controlling heat absorption for the temperature of the photoelectric conversion part in the vicinity of a predetermined temperature. |
