Abstract
Abstract An X-ray diagnostic apparatus has a first X-ray generating portion for imaging of over-table tube, a second X-ray generating portion for imaging of under-table tube, and an X-ray detecting portion having a compact and light solid state detector light attached to an elastic stay portion suspended from a ceiling to a floor. The solid state detector is supported by a central rotating arm for enabling central rotation about a central axis of the solid state detector, and an elastic offset rotating arm for enabling offset rotation dislocated from the central rotation. Therefore, by virtue of each rotation and the extension and contraction operation and further its compactness and lightness, the solid state detector can be accurately and rapidly set to various positionings in upward, downward, leftward, rightward and slanting positions, etc. with respect to a subject on a diagnostic table. An image of the subject is picked up by property using either of the X-ray generating portions in accordance with the positionings of the solid state detector.
