Simulation Calculation of Integrating Factor for Image Reconstruction Algorithm in High Energy Computed Tomography Detection

A new algorithm was designed to improve the precision of reconstructing images for nuclear devices, according to its particular case. The integrating factor of image reconstructing algorithm was rectified for computer tomography (CT) scanning through using a large number of pre-knowledge of nuclear devices and Monte Carlo program. It is validated that this algorithm can suppress the disturbance of scattering and cross-talk. And the precision of CT scanning is improved greatly through image reconstruction simulation.
