Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray tube, a driver, a supporter, and processing circuitry. The X-ray tube including a rotating anode. The driver rotates the rotating anode. The supporter supports the X-ray tube in an inclinable manner. The processing circuitry acquires information indicating an attitude of the supporter and controls the driver based on information indicating the acquired attitude.

Abstract: An X-ray diagnostic apparatus comprises an X-ray tube and processing circuitry. The X-ray tube includes a rotary anode. The processing circuitry is configured to derive an acquiring condition from a fluoroscopic image, and start to increase, in accordance with the acquiring condition derived, a rotating speed of the anode from a low rotating speed to a high rotating speed before the X-ray tube finishes emitting an X-ray to acquire the fluoroscopic image.

Abstract: An X-ray diagnostic apparatus according to embodiments includes an X-ray tube assembly and a grid potential control circuitry. The X-ray tube assembly includes a filament that emits electrons, a target that generates X-rays by receiving the electrons, and a grid having a potential for adjusting a potential gradient around the filament. The grid potential control circuitry switches the potential of the grid to a potential where the potential gradient around the filament becomes greater than a potential gradient generated by a potential of the filament and a potential of the target.
