摘要
在建立X光机成像系统物理模型的基础上 ,分析了低对比度分辨和空间分辨机理、系统生成供人可观察图像之局限因素 ;在简述低对比度分辨能力和空间分辨能力评价的同时 ,讨论了某些分辨能力检测法的科学性。
On the basis to establish a physical model of the X-ray equipment imaging system,the mechanism of the low contrast resolving and space resolving as well as the limiting factors for the system to produce a man-observable image have been analyzed.While briefly describing the evaluation on low contrast resolution and space resolution,the article has discussed the scientific character of some concrete evaluation approaches.There is test result to include.
