摘　　要：目的:探讨如何提高成像质量,减少废片率,降低病人辐射剂量,从而减低医疗运行成本。方法:2007年-2013年,根据质控要求对每天的图片质量进行评估,结合用片量,算出废片率。定期对废片产生的原因进行分析,提出改进措施并在临床工作中执行。结果:2007年废片率为评定0.29%,2009年为0.12%,2009年比2007年降低17%;2010年为0.14%,2013年为0.06%,2013年比2010年降低8%;2007-2013年这7年的平均废片率为0.12%。结论:对技术工作严格管理,按质控标准操作,对废片产生的原因进行认真分析并进行改进,能有效降低废片率。Objectire：To explore the effective method to improve the quality of imaging,reduce waste film,radiation dose and medical cost.Method：According to image quality control protocol,the quality of images in our department was as-sessed every day from 2007 to 2013.The causes for waste films were analyzed and then improvement was carried out.Waste rate was calculated.Results：The rate of waste film in 2007,2009,2010 and 2013 was 0.29%,0.12%,0.14% and 0.06%, respectively.Compared with that of 2007,the waste rate of 2009 was reduced 17%,and when compared wtih 2012,the waste rate of 2013 was reduced 8%.The mean waste rate in the 7 years was 0.12%.Conclusion：Strict quality control,anal-ysis of the causes of waste films and improvement in daily work can be effective methods to reduce the rate of waste film.
