Abstract:
1. An X-ray diagnostic apparatus comprising: a tabletop on which an object is placed; a tabletop support configured to support the tabletop movably in a longitudinal direction, a raising/reclining direction, and an upper/lower direction of the tabletop; an arm configured to hold an X-ray tube and an X-ray detector movably in an approaching/separating direction with respect to the tabletop support, the X-ray tube being configured to irradiate the object placed on the tabletop with X-rays, the X-ray detector being configured to detect X-rays transmitted through the object; a position storing unit configured to store a photographing position of the arm and a photographing position of the tabletop in association with each other for each photographing of the object; and a mechanism controlling unit configured to move, when the arm is at a retraction position at which irradiation of the object on the tabletop with X-rays is impossible, the tabletop in the raising/reclining direction and the upper/lower direction so as to maintain a position in at least the upper/lower direction of a region of the object corresponding to a photographing position of the arm stored by the position storing unit.
