| 摘 要： | 在临床应用中,我们发现不同的设备配有不同的图像后处理软件,因此在使用操作、处理效果上存在明显的差异。以数字胸片为主要研究对象,通过对图像进行小波变换,根据不同通道的子图像提取纹理和能量特征,进行物理特征分析,对比不同设备所产生的DR图像在主观观感上的特点。

| Abstract: | As an important instrument in clinical application,DR（digital radiography） system has become the most popular and significant method in physical examination.The image processing system which the DR system has may cause different results of seeing.The reason for which is that the image processing system depends on the DR system itself,which comes from different providers.This article is mainly about the analysis of characters of the images from different DR systems. |
