【摘要】 为解决ART算法重建时间较长这一问题,作者采用PC机群的并行处理技术,将ART重建算法改写为并行运算方式。并行运算结果表明:图像重建速度与CPU的个数(6个)基本上成线性正比关系,且不影响图像的重建质量。从而使迭代法在线重建成为可能。更多还原

【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.更多还原
