An X-ray computed tomography apparatus includes an X-ray tube configured to emit X-rays, an X-ray detector configured to detect X-rays passing through a subject in order to acquire projection data, a processor configured to reconstruct tomographic image data on the basis of the projection data, and an interlock unit configured to monitor generation of an arc in the X-ray tube. When an arc in the X-ray tube is detected, the interlock unit stops emitting X-ray emission from the X-ray tube. When a predetermined period of time elapse from the stop of X-ray emission, the interlock unit restarts X-ray emission from the X-ray tube.
