| 摘 要： | Mastel/Slave模式,又称主从模式,是一种并行程序设计思想。本文介绍了同时代数重建法(SimultaneousAlgebraicReconstructionTechnique,SART),并简化、改进了该算法:讨论了SART算法的并行性和基于Master/Slave模式的并行进程:通过算法复杂度分析和在以客户/服务器((Cient/Serve)模式组建的局域网上的网络并行重建试验,证明了该并行进程能较大地提高SART算法的时间效率。

| Abstract: | Master/Slave mode is a kind of design idea for parallel programming. In this paper, Simultaneous Algebraic Reconstruction Technique (SART) was introduced, and its algorithm was predigested and improved. The parallel performance of SART as well as the parallel course based on Master/Slave mode was discussed. According to the complexity analysis of algorithm and parallel-reconstruction experiment on local network based on Client/Serve mode, the parallel course could improve the time efficiency of SART algorithm. |
