基于matlab的平行束滤波反投影重建算法
- 平行束的CT成像,对投影线经过的像素做线积分,积分得到的值保存为该角度下的权值 对一组数据 P 做 Radon 变换,即做正投影,会得到两个数据(Parallel beam CT imaging)
平行束
- CT成像过程中,X射线平行入射,做两次变换可得CT图像。(In the process of CT imaging, CT images can be obtained by two times conversion of X ray parallel incidence.)
FBP
- 平行束滤波反投影算法的实现和几种常用滤波器的实现。(The implementation of parallel beam filter backprojection algorithm and the implementation of several common filters.)
