    摘要: 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.

    摘要: Provided is an X-ray imaging system capable of performing X-ray imaging quickly. The X-ray imaging system is provided with: an X-ray tube device including a cathode and an anode, the X-ray tube device being capable of performing X-ray imaging by irradiating an imaging target with X-rays in a state of rotating the anode; a light irradiation device including a collimator defining an X-ray irradiation range of the X-rays with respect to the imaging target, a visible light irradiation unit for emitting visible light to the imaging target and a light irradiation operation unit for performing an operation for making the visible light irradiation unit in the light irradiation state; and a controller for controlling operations of the X-ray tube device and the light irradiation device. The controller rotates the anode at an imaging possible rotation speed capable of performing X-ray imaging when the light irradiation operation unit is operated.
