X-ray imaging apparatus

An X-ray imaging apparatus provided with a cathode, an anode, a rotation drive unit for rotating the anode to a predetermined operation speed, and an X-ray tube for emitting X-rays from the anode toward a subject by applying a high voltage between the cathode and the anode, the anode being rotated at the predetermined operation speed, the X-ray imaging apparatus comprising:

• a main power supply operation unit configured to switch ON/OFF of power supply to the X-ray imaging apparatus;
• a braking unit configured to decrease a rotation speed of the anode to a braking speed lower than a resonance speed that 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,
• wherein 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.
