Our study indicates that the origin of this blurring effect is the Compton scattered radiation within the entrance window, the mounting of the detector scintillator and other parts of the detector. This effect becomes, in particular, noticeable in the presence of a sharp edge of a metallic component being tested, making the scattering in the detector asymmetric.enpoint spread functionblurringx-ray flat-panel pixel detectorcomputed tomography620658670621681journal article
