ABSTRACT

Objective To improve the CR image quality and to promote the digital image standard constitution by analyzing the common problems and malpractiees in application of computed radiography. Methods Phenomenon and reasons of 107 CR junk-films from nine three-"A"-hospitals were analyzed, discussed,recorded,and statistised by 20 radiologists,radiographers and engineers.Results Among 107 junk fihns,there are 36 cases(33.64%)of incorrect operations,29 cases(27.10%)of artifacts in reading and transferring the data of IP,15 cases(14.02%)of artifacts in IP system,and 13 cases (12.15%)of selection of inappropriate radiographic parameters,and 9 eases(8.41%)of printer-failures, and 5 eases(4.67%)of inappropriate post-processing techniques.By analyzing the reasons of 107 junk films we found that 60.74% were due to less responsibilities and incorrect operations,and 35.51% were due to new problems in CR techniques,and other were due to inappropriate post-processing techniques. Conclusion Responsibilities,operation regulations,digital image quality standards,studying of new techniques and appropriate use of the post-processing techniques are the key points for improving the CR image quality and the diagnosis level.
