PROBLEM TO BE SOLVED: To improve image quality of a CT image by facilitating temperature control of a detection element through a simple structure, particularly to apply temperature control even when an X-ray detector is made closer to or integrated with a DAS (data acquisision system), in an X-ray CT apparatus.SOLUTION: This X-ray CT apparatus 1 includes an X-ray tube 21 which generates an X-ray, an X-ray detector 22 which detects the X-ray, a temperature sensor 32 which perceives the temperature of the X-ray detector 22, a DAS 24 which acquires data from the X-ray detector 22, and a controller 26 which controls the temperature of the X-ray detector 22 to which the temperature sensor 32 is attached through adjustment of a workload of the DAS 24 during a non-scanning time. |
