Abstract
A second C-shaped arm 5 is provided along an inner periphery of a first C-shaped arm 4, and a slide operation of the first C-shaped arm 4 is controlled and a slide operation of the second C-shaped arm 5 is controlled along the inner periphery of the first C-shaped arm 4. Accordingly, wide angle setting can be achieved to thus enable various positionings. Further, the second C-shaped arm 5 is controlled to be rotated over 360.degree. along the inner periphery of the first C-shaped arm 4 and an X-ray generator 6 is controlled to irradiate an X-ray intermittently or continuously every predetermined angle, so that three dimensional reconstruction can be accomplished based on image information every angle. As a result, three dimensional radioscopic images, etc. can be formed based on necessary and sufficient image information, whereby the X-ray diagnostic apparatus can be used like an X-ray CT apparatus.
