<p><P>PROBLEM TO BE SOLVED: To provide an X-ray image diagnostic apparatus capable of sliding a top panel or an imaging unit to the next stage matched with the flow of a contract medium and performing stepping DSA imaging. <P>SOLUTION: The X-ray image diagnostic apparatus includes: an imaging unit that supports an X-ray generation unit and an X-ray detection unit facing each other and is capable of taking an image of a subject placed on a top panel of a bed; a control unit that executes control to move at least one of the imaging unit and the top panel stepwise in the body axial direction of the subject and take the image of the subject at a plurality of stages; and an image processing unit that processes image data taken at the plurality of the stages. The control unit sets a plurality of regions of interest in the body axial direction of the subject when injecting a contrast medium into the subject and taking an image, measures a change of an image level in the region of interest to detect the flow of the contrast medium, and moves at least one of the imaging unit and top panel to the next imaging stage based on the detection result. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
