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, an X-ray variable diaphragm, an X-ray detector, and processing circuitry. The X-ray tube irradiates X-rays. The X-ray variable diaphragm limits an irradiation region of the X-rays. The X-ray detector detects the X-rays that have passed through an object. The processing circuitry controls a movement of the X-ray tube, the X-ray detector, and an aperture of the X-ray variable diaphragm such that, when the irradiation region on the X-ray detector moves within an imaging range, a movement velocity of the irradiation region relative to the imaging range is maintained constant.
