Improvement of Image Quality in Transmission Computed Tomography Using Synchrotron Monochromatic X-Ray Sheet Beam

Abstract

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, In order to achieve more reliable reconstruction, we propose the data-correction and estimation method based on the properties of the facilities and the principle of CT reconstruction, and confirm its effectiveness using a physical phantom.
