| Abstract: | On the basis of the parallelizability of the algorithm for convolution back projection and the advantages of workstation cluster, the parallelization of image reconstruction in convolution back projection with narrow fan-beam based on workstation cluster was proposed and discussed. It was pointed out that the parallelization could play an important role in the fast image reconstruction of the high-energy ICT with high ratio of property to price. |
