摘要
卷积反投影是二维图像重建的一种典型算法。本文讨论了针对不同机器结构的并行化设计策略，并分别在Ｔｒａｎｓｐｕｔｅｒ并行机、ＢＪ－１、曙光一号上设计实现了卷积反投影的并行算法。文中还对实验结果进行了对比分析。
Reverse Project Technique (RPT) is a typical image reconstructed algorithm. In this paper, parallel algorithms for RPT are devised and implemented in Transputer system, BJ 1 parallel computer and DAWNING 1 parallel computer respectively. Based on the analysis of the different efficiencies achieved with the three parallel computers, the complicated factors that affect the performance of a multicomputer system are also discussed.
