<p>PROBLEM TO BE SOLVED: To reduce a contrast imaging burden of a subject at the time of performing contrast rotation imaging twice or more.SOLUTION: An X-ray diagnostic apparatus comprises: a substantially C-shaped arm; a support mechanism which rotatably supports the substantially C-shaped arm; a rotation drive part which drives the rotation of the substantially C-shaped arm; an X-ray tube which is mounted in the substantially C-shaped arm; a high voltage generation part which generates high voltage for generating an X-ray from the X-ray tube; an X-ray detector which is mounted in the substantially C-shaped arm in a direction facing the X-ray tube; and a rotation imaging control part which controls the operations of the support mechanism, the high voltage generation part and the X-ray detector for continuously or intermittently generating the X-rays from the X-ray tube while rotating the substantially C-shaped arm and repeating rotation imaging operations of repeating X-ray detection with the X-ray detector in plural times after single contrast medium injection, and performs time control management on each of the plurality of rotation imaging operations with the time using the time of the single contrast medium injection as an origin.</p> |
