Abstract
The X-ray imaging apparatus includes: a main power supply operation unit for switching ON/OFF of power supply to the X-ray imaging apparatus; a braking unit for decelerating a rotation speed of the anode to a predetermined braking speed lower than a resonance range which is a rotation speed of the anode at which resonance occurs in the X-ray tube; and a non-braking stop prediction unit configured to detect a predetermined situation in which a non-braking stop state is predicted, the non-braking stop state being a state in which the main power supply operation unit is operated to be turned to an OFF state without decelerating the rotating anode by the braking unit. The non-braking stop prediction unit activates the braking unit by detecting the predetermined situation to decrease the rotation speed of the anode to the braking speed.
