PURPOSE:To appropriately determine the blood circulation state of an examinee, by recording one set of mask image groups before the injection of a contrast medium and plural sets of live image groups after the injection of the contrast medium on separate recording medii. CONSTITUTION:A scanning apparatus 5 allows an X-ray tube bulb 1 and a detector 3 to repeatedly and relatively move on the basis of the driving control signal from a control part 11 to successively perform tomographic imaging several times. One set of mask image groups before a contrast medium is injected in an examinee and plural sets of continuous live image groups after the injection of the contrast medium are obtained and recorded on separate frame memories 7a-7n. Thereafter, an operation apparatus 8 executes image re- constitution processing containing subtraction processing using said images. |
