Comparative Analysis of FBP and OSEM Reconstruction Methods in Industrial CT

FBP and OSEM are the most frequently used methods in image reconstruction.In this paper,we report the application of these two methods in the reconstruction of industrial CT,compare and analysis the reconstructed results of the two methods in different detector bin numbers,different samplings of angles,and different noise levels.The conclusion is that the reconstruction results of iterative OSEM are better than those of analytic FBP in certain conditions.
