摘　　要：目的找出伪影产生的原因并采取相应的解决方法,减除伪影,提高CR影像质量。方法收集显示有伪影的CR胶片243张,分析伪影形成原因并探讨相应的解决方法。结果共找到13种伪影产生原因,如IP不洁产生的伪影、IP自身生成的伪影、荧光物质老化产生的伪影等,且每种伪影的消除方法也已探讨出来。结论针对性的解决方案能够有效减除伪影,提高诊断质量。Objective To find the formation causes of artifacts and adopt corresponding solutions to eliminate the artifacts in CR films so that the image quality can be improved. Methods Collecting 243 CR films 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 fluorescent 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.
