<P>PROBLEM TO BE SOLVED: To assist accurate diagnosis. <P>SOLUTION: An X-ray diagnostic apparatus includes an X-ray generation part, an X-ray detection part, an arm, an arm drive part, and a photography control unit. The X-ray generation part generates X-ray. The X-ray detection part detects X-ray radiated by the X-ray generation part. The arm supports the X-ray generation part and the X-ray detection part so that the X-ray generation part and the X-ray detection part face each other while holding a subject between them. The arm drive part performs rotary driving of the arm. The photography control unit controls the X-ray generation part, the X-ray detection part, and the arm drive part so as to photograph the subject by X-ray from a first direction and a second direction. The photography control unit decides the first direction and the second direction so that a part of interest showing a part of a photography object part of the subject is included in an overlap area where a first photography visual field when the X-ray is emitted from the first direction overlaps a second photography visual field when X-ray is emitted from the second direction and that parts other than the part of interest are not included in the overlap area. <P>COPYRIGHT: (C)2012,JPO&INPIT |
