PROBLEM TO BE SOLVED: To provide an X-ray CT apparatus including a control circuit in which a low-load indication light and a high-load indication light are compatible to enable control of both of the indication lights with a single circuit configuration.SOLUTION: An X-ray CT apparatus includes an indication light control unit putting an indication light on or off in accordance with the operation status of the apparatus. In the apparatus, the indication light control unit includes: a control circuit outputting an on signal or an off signal for putting on the indication light or putting off the indication light in accordance with the operation status of the apparatus; a semiconductor relay for applying or interrupting the current of AC power supply supplied to the indication light on the basis of the on signal or the off signal; and a capacitor connected to the load in parallel when making the indication light loaded by the AC power supply. |
