Generate_SystemMatrix
本程序在matlab中运行。
Generate_SystemMatrix是一个计算OSEM,MLEM迭代图像算法中系统矩阵的函数,其用法Generate_SystemMatrix(pixel),为所要重建图像的大小,一般为64,128,256,pixel也大运算越慢。
里面的diedai-test文件是一个简单的MLEM重建算法,其中要加载SystemMatrix矩阵就是Generate_SystemMatrix(128)的结果,注意如果要运行diedai-test,生成的系统矩阵名要保存为SystemMatrix,否则出错。
testsino是一个正弦图实例,就是MLEM算法中的投影矩阵,机算是数据。(This program is run in matlab. The Generate_SystemMatrix is a calculation of the OSEM, a function of the system matrix MLEM iterative image algorithm, its use Generate_SystemMatrix (pixel) to rebuild the image size, usually 64,128,256, pixel also large computing slower. Inside diedai-test file is a simple MLEM reconstruction algorithm, which load SystemMatrix matrix is the result of Generate_SystemMatrix (128), pay attention to if you want to to run diedai-test, the generated system matrix is saved as SystemMatrix, otherwise an error. testsino instance of a sinogram projection matrix MLEM algorithm, machine be regarded as data.)
