Abstract
Objective To find the formation causes of artifacts and adopt corresponding solutions to eliminate the artifacts in CR iflms so that the image quality can be improved. Methods Collecting 243 CR iflms with artifacts, analyzing the formation causes and discussing the elimination methods of the artifacts. Results 13 kinds of formation causes are found such as artifacts due to the unclean Ip board, artifacts due to IP, artifacts due to lfuorescent material aging and so on. Elimination methods for each of these artifacts are also found. Conclusion Corresponding solutions can eliminate the artifacts effectively to improve the diagnosis quality .关键词
