PROBLEM TO BE SOLVED: To provide an X-ray CT (Computed Tomography) system capable of being operated by limiting average power consumption. SOLUTION: The system includes a power saving mode. In the power saving mode, average supply power Wa to an X-ray tube is calculated, which is the power when performing an input scanning plan (S24), so as to determine whether the average supply power Wa is equal to or more than a prescribed value Wth (S25). When the determination is NO, the scanning parameter of the scanning plan is changed to allow the average supply power Wa to be equal to or less than the prescribed value Wth (S26). In this case, only the parameter for specifying a non-exposure time is changed in a peak power priority mode, only the parameter for specifying supplied power is changed in a time priority mode, and both the parameters are changed in a balance mode.
