基于matlab的fbp滤波反投影算法-Based on the fbp matlab filter back projection algorithm

通过对投影数据进行滤波反投影从而得到图像的FBP算法，设置的滤波器可以自行更改为其他的-Through the projection data is filtered back-projection algorithm to obtain an image of the FBP, the filter settings can be changed to other self-

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.)
