ABSTRACT:
An apparatus for improving the tomographic image quality by preventing the tomographic image contrast from degrading and preventing artifact from occurring even if many scattered radiations occur. An X-ray detection array obtains first detection data using the X-ray detection elements corresponding to an area not shielded by a collimator. Further, the X-ray detection array obtains second detection data using the X-ray detection elements corresponding to an area shielded by the collimator. A central processing unit corrects the first detection data based on the detection data including the first and second detection data. Finally, the central processing unit generates a tomographic image for an imaging area of the imaging object.
