Computer Simulation of Three-Dimensional Refractive Index Field From Iterative Convolution
摘要
介绍了迭代卷积重建算法的教值过程,用Turbo C 2.0开发了该算法的实用软件.通过计算机模拟运算,考查了其重建精度、重建误差与投影方向数和迭代次数的关系.结果表明,该软件对180°范围内均匀投影采样,投影数为6,迭代次数为8～10次,仍具有较好的重建精度.
Abstract
The process of numerical value of iterative convolution algorithm is presented and a practical software is developed with turbo C 2.0. By means of computersimulation, we checked the reconstructed precision of this software and the relationship of reconstructed error with projective direction numbers and iterative numbers. The results show that this software has a good reconstructed precision as the projective sampling at equal interval over 180°, with the projective numbers of 6 and the iteration numbers of 8～10.
