The X-ray diagnostic apparatus according to any of embodiments includes an X-ray tube, an X-ray detector and processing circuitry. The X-ray tube is configured to irradiate an imaging region of a subject with X-rays. The X-ray detector is configured to detect the X-rays. The processing circuitry is configured to acquire an incident angle of the X-rays corresponding to a clinical purpose of the imaging region, and acquire image data from an image sensor that images the imaging region. The processing circuitry is configured to rotate the X-ray tube in accordance with the acquired incident angle of the X-rays, and slide a position of a central path of the X-rays with respect to the imaging region based on the image data.

X-ray diagnostic apparatus

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.

X-ray diagnostic apparatus and X-ray high-voltage generator

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.
