Abstract

In order to solve the problem that the computing time of ART is too long,we rewrite the algorithm into parallel format and run it on the PC cluster.By parallel computing,the speedup factor is roughly equal to the number of CPUs and the precision of reconstruction is the same.This technique is very suitable for real-time reconstruction with iterative methods.
