变色龙算法(Chameleon)，在matlab中的实现(Chameleon algorithm (Chameleon), in the realization of matlab)

应用matlab编程，实现了对CT图像的重建(reconstruction for CT image)

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 method to solve, relatively new.)

A cyclic redundancy check (CRC) is an error-detecting code designed to detect accidental changes to raw computer data, and is commonly used in digital networks and storage devices such as hard disk drives. Blocks of data entering these systems get a short check value attached, derived from the remainder of a polynomial division of their contents on retrieval the calculation is repeated, and corrective action can be taken against presumed data corruption if the check values do not match.
