摘　　要：CR系统是实现X线平片数字化较成熟的设备。与传统X线摄影相比,CR系统提高了图像质量,降低了辐射剂量,其图像后处理技术更适应现代诊断要求,真正实现了常规X线影像的数字化储存、再现和信息联网。通过剖析CR系统成像原理,系统地对可能影响成像质量的各个环节和因素进行了探讨,并对影像质量控制进行了分析和评估,提出了控制和提高影像质量的具体对策,旨在提高对CR影像质量的认识,从而更好地为临床服务。The CR image system is a widely-used device to digitize X-ray images. The superiority of CR image system over a traditional X-ray camera shows that the former has a higher image quality and a less radiation dosage. Moreover, the CR image allows easier post-processes to convince the diagnoses and enables digital storage, reproduction and access on line. By analyzing the basic theory of CR image systems, the potential factors to impact the image quality are discussed. A series of strategy to improve the CR image quality are proposed.
