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

用MATLAB实现了CT平行束滤波反投影和扇束滤波反投影重建过程，效果良好，其中radon变换的方法采用步长法求解，较新颖。-CT achieved using MATLAB parallel beam filtered back projection and fan-beam filtered back projection reconstruction process, to good effect, in which radon transform method using step me
