Abstract: 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.

Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray irradiator, a scatterer, a grid, and a detector. The X-ray irradiator irradiates X-rays. The scatterer is provided between the X-ray irradiator and an object, that scatters the irradiated X-rays. The grid is provided between the scatterer and the object, that transmits the scattered X-rays within a predetermined angular range. The detector detects X-rays transmitted through the object together with an incident angle of the X-rays.
