摘要:
According to one embodiment, an X-ray diagnostic apparatus includes an X-ray generation unit, X-ray detection unit, X-ray beam limiting unit, and X-ray beam limiting control unit. The X-ray generation unit generates X-rays. The X-ray detection unit detects the X-rays generated by the X-ray generation unit and transmitted through an object placed on a tabletop. The X-ray beam limiting unit includes a plurality of filters to harden radiation quality of the generated X-rays. The X-ray beam limiting control unit controls the X-ray beam limiting unit to place a filter between the X-ray generation unit and the object, which filter is specified from the plurality of filters based on the thickness of the object and the distance between the X-ray generation unit and the X-ray detection unit.
