摘　　要：目的探讨如何对CR床边摄影进行有效的质量控制,提高CR床边摄影的影像质量。方法利用床边X线机及CR系统对需床边X线检查的3300例病人进行投照,并编号CR片盒、定期清洁IP板及片盒、定期业务学习等。结果实行质量控制前、后对比,甲级片率由的51%提高到58.2%,甲级片率上升了7.3%,乙级片率由45.5%下降到40%,丙级片率由2%下降到1.3%,重照率由1.5%减低到0.5%;影像质量稳定。结论对CR床边摄影进行质量控制能使床边摄影质量得到提高,同时减轻了工作人员的劳动强度。Objective To study the quality controll of bedside CR examination and improves the imaging quality. Methods X-ray examination with CR system were performed on 3,300 patients. All CR cassettes were encoded. The imaging plate and cassettes were cleaned regularly. Results With and without quality control, the percentage of first-rote film was 58.2% and 51%, the second-rate film was 40% and 45.5%, the third-rate film was 1.3% and 2%, respectively. Correspondingly, the ratio of re-examination decreased from 1.5% to 0.5% after quality control, and imaging quality was stable. Conclusion The quality control of bedside CR examination can improve the image quality as well as lighten the labor of radiographers.
