Abstract

X-ray fluorescence computed tomography (XFCT), as a non-invasive imaging technique, has attracted much attention for its simulation and reconstruction. In this study, we built a simulation model of cone-beam X-ray fluorescence CT using Geant4 and simulated the propagation and interaction process of X-rays in the phantom by Monte Carlo simulation. Then, we acquired the projection data and used the FDK (Feldkamp-Davis-Kress) resolution algorithm to reconstruct the images in three dimensions. The results show that cone-beam X-ray fluorescence CT combined with the FDK algorithm can effectively reconstruct the images, which provides strong support for non-invasive imaging and trace element distribution analysis.
