ABSTRACT:
An X-ray CT apparatus includes X-ray tubes, slit mechanisms which are respectively provided for X-ray tubes and whose slit widths can be changed, two-dimensional array type X-ray detectors which form pairs with the X-ray tubes, a support mechanism which supports the X-ray tubes and the X-ray detectors so as to allow them to rotate about a rotation axis parallel to the slice direction, a correction unit which corrects data from each detection element located in an area which X-rays passing through the slit mechanism directly strike, by using data from at least one detection element located outside the area and associated with the same channel in order to reduce a scattered radiation component originating from X-rays generated by an X-ray tube other than the X-ray tube forming the pair, and a reconstruction unit which reconstructs image data on the basis of the corrected data.
