PROBLEM TO BE SOLVED: To reduce an exposure does in the entire technique when performing volume fluoroscopy for a region spreading in a body axial direction. SOLUTION: In a technique planning stage, an object region is specified (S11), an imaging region including a specified object region is set (S12), the minimum photography region including the set imaging region is set (S13) and a photography condition is set matched with the set photography region (S14). In a technique performing stage, system control is started on the basis of the photography condition (S21), scan is performed (S22), and image reconstitution is performed (S23). In the stage, the correction of the object region (S24), the correction of the imaging region (S25), the correction of the photography region (S26) and the correction of the photography condition (S27) are performed and condition change is confirmed (S28). Return to the system control (S21) is performed when the condition is changed, and continuation/end is finally judged when the condition is not changed (S29). Return to the performance of the scan (S22) is performed at the time of continuation, and a series of processing is ended at the time of end. COPYRIGHT: (C)2008,JPO&INPIT
