目的：通过对床边DR的影像质量的影响因素分析，总结DR床旁摄影的经验与教训，提出改进方法。方法对1265份数字化X线影像资料（1265张影像片）进行回顾性分析，并按部位、阳性率及图像质量进行统计和分析，探讨影响成像质量因素。结果1265份影像片中，甲级片1032张，甲级片率为81.6％；乙级片181张，乙级片率为14．3％；丙级片52张，丙级片率为4．1％，没有废片。对233张非甲级片进行影像质量原因统计、分析及分类。其中由设备性能问题所致为39张，占16．7％；图像噪声：15张，占6．4％；摄片技术：101张，占43．3％；图像后处理：31张，13．3％；激光相机与打印：10张，占4．3％；人为因素的影响37张，占15．9％。结论影响DR照片质量因素很多，技术人员的操作技能和水平是其主要因素。

Objective To analyze the influence factors of quality of bedside digital radiography DR image , and summrize the experience and lessons of DR bedside photography ,and put forward some suggestions and improve-ment methods ,and continuously improve the clinical value of DR .Methods The data of 1 265 cases of digital radio-graphy DR imaging(1 265 imaging films) were retrospectively analyzed ,and were statistically analyzed according to the site,the positive rate and image quality .Influence factors of the imaging quality was explored .Results In 1 265 films,the A-level images were 1 032 cases,the rate of A-level was 81.65%,and the B-level images were 181 cases, the rate of B-level was 14.30%,and the C-level images were 52 cases,the rate of C-level was 4.10%,and there was no rejected film.The image quality of 233 non-A-level images were statistically analyzed and classified .39 cases caused by the equipment performance problems ,accounting for 16.70%;15 cases caused by the image noise ,account-ing for 6.40%;101 cases caused by radiography technology ,accounting for 43.30%;31 cases caused by image pro-cessing,13.30%;10 cases caused by laser printer and print ,accounting for 4.30%;37 cases caused by the influence of human factors,accounted for 15.90%.Conclusion It is demonstrated that there are many factors influence DR image quality and the main factor is operation skill of technician .
