摘要
目的探讨CR伪影产生的原因及控制措施。方法回顾性分析具有伪影的CR影像120例。结果 120例中,CR硬件伪影23例,成像板伪影27例,激光打印机伪影10例,影像阅读器伪影18例,滤线栅伪影9例,X线曝光剂量产生的伪影15例,CR图像后处理伪影12例,人为操作不当伪影6例。结论确保CR整个成像链的每一个环节的最佳工作状态,是获得优质影像质量的关键。
Objective To probe the causes CR artifacts and control measures of.Methods Retrospective analysis CR Images of 120 patients.Results In 120 patients,there were the hardware artifact in 23 cases,imaging board artifact in 27 cases,laser printers artifact in 10 cases,image reader artifact in 18 cases,filter line cegrate artifact in 9 cases,X-ray exposure dosage artifacts in 15 cases,CR image post-processing artifact in 12 cases,and artificial improper operation artifact in 6 cases.Conclusion Ensuring whole imaging chain of the CR in the best working state can obtain the good image quality.
