In the transmission CT imaging system with scintillator-CCD detector using synchrotron monochromatic x-ray as sheet beam, improvement of reconstructed image quality is investigated. The properties of experimental facilities cause the incident beam intensity to be spatially inhomogeneous, and to temporally attenuate.
