- W2144921531 abstract "The first exact spiral cone-beam CT reconstruction algorithm was developed by Katsevich (2002, 2004). Recently, Yu and Wang (2004a, 2004b) implemented the algorithm numerically. Although the method is very promising, the computation is very intensive. It requires huge amounts of computational time. Recently, people (Deng et al., 2006; Yang et al., 2006) began to parallelise the algorithm for achieving high performance computing (HPC). This paper presents a performance analysis of the parallel Katsevich algorithm (Deng et al., 2006) by developing an analytical expression to evaluate the performance of the algorithm parallelism. The results from the analytical model and numerical experiments are compared in a fair agreement. The analytical model provides a useful tool to estimate HPC benchmarks in the parallel Katsevich algorithm." @default.
