| 摘 要： | 课题组设计了新型的X射线影像增强系统。由于它是由多个光电器件级联而成的链状成像系统，在组成器件之间存在着一定的分辨率函数关系，并且这种函数关系会随着成像视野的变化而变化．鉴于此种关系，建立了系统的分辨率数学模型，对多种器件组合效果进行理论分析。结果表明分辨率理论计算值和实验测量值比较吻合，所以分辨率数学模型节省了系统的设计时间和费用，对提高系统分辨率起着理论指导作用。

| Abstract: | A novel x-ray intensifying system was designed in our lab. Because it is cascaded and composed of the intensifying screen and the brightness intensifier, there must be a resolution relationship among the components. A model was set up to describe this relationship. By using this model, the theoretical resolution values of the whole x-ray imaging system can be calculated, which is referential to the selection of the components in the course of the system design. |
