Abstract
According to one embodiment, an X-ray diagnostic apparatus includes an X-ray tube, an X-ray detection unit, an X-ray filter, an input unit, and an X-ray filter support unit. The X-ray tube generates X-rays. The X-ray detection unit detects the X-rays transmitted through a subject. The X-ray filter is arranged between the X-ray tube and the object and has an opening. The X-ray filter support unit supports the X-ray filter so as to make the X-ray filter movable in an imaging axis direction of the X-rays.

An X-ray diagnostic apparatus comprising:
- an X-ray tube configured to generate X-rays;
- an X-ray detector configured to detect X-rays generated from the X-ray tube and transmitted through an object;
- an X-ray filter configured to be arranged between the X-ray tube and the object and having an opening;
- and
- an X-ray filter support unit configured to support the X-ray filter so as to make the X-ray filter movable along an imaging axis direction of the X-rays.
An X-ray diagnostic apparatus comprising:
- an X-ray tube configured to generate X-rays;
- an X-ray detector configured to detect X-rays generated from the X-ray tube and transmitted through an object;
- a plurality of types of X-ray filters configured to be arranged between the X-ray tube and the object;
- and
- an X-ray filter support unit configured to support the plurality of types of X-ray filters so as to make the plurality of types of X-ray filters movable along an imaging axis direction of the X-rays,
- wherein the plurality of types of X-ray filters include respective attenuation coefficients different from each other.
A diagnostic method comprising the steps of:
- arranging an X-ray filter between an X-ray tube and an object;
- irradiating the object with X-rays using the X-ray tube;
- detecting X-rays generated from the X-ray tube and transmitted through the object;
- and
- moving the X-ray filter along an imaging axis direction of the X-rays.
