ABSTRACT
Objective:Through to the CR in imaging, scanning and transmission process of artifact analysis, find out the causes of artifacts, and to explore methods and countermeasures to reduce and eliminate artifacts, improve the quality of CR picture. Methods:Collected between September 2009 and mid-February 2012 CR images of 103 cases with artifacts, through the analysis of the morphology and characteristics of image artifacts on the causes of artifacts. Results:from 103 have artifacts in the image analysis and proof, the photography, scanning and so on ordinary maintenance produces CR image artifacts, most of the artifacts, through the corresponding processing, most of them can reduce and eliminate. Conclusion:As long as technicians and maintenance engineers to strengthen the sense of responsibility, familiar with the working principle of CR equipment and strengthen the ordinary maintenance, CR image artifacts can be avoided and eliminated.
