摘要
首先叙述了CR(computer radiography)系统的工作原理.在针对具体的成像环节进行详细分析的基础上,归纳了CR图像获取过程中产生的噪声原因及其所属类型.实验结果证明了降低图像噪声的方法取决于图像中的噪声类型.此结论对于恢复原始图像的噪声滤波方法的选择具有重要意义.
First,the working principle of CR（computer radiography）system is described in this paper.Then,on the basement of detail analyzing on the imaging system,the reason of the noises increased and its corresponded type of noise is classified for the CR system.The conclusion of the adopted method to reduce the effect of image noise depends on the type of image which is given.This conclusion is very important for the choice of noise filter during the image restoration processing.
