本文对射线照相系统参数函数化控制底片黑度的可行性进行分析,首先阐述了射线照相理论及相关公式;接着对公式进行推导、对黑度的影响因子加以分析提炼简化、对数据收集进行分析、对影响因子的实验方案设计进行了简单规划,接着对其黑度函数的应用和维护进行了说明;最后阐明不足及对其应用前景进行了展望。 In this paper, we analyzed the feasibility of parameterized control of the blackness of the film by using the parameters of the radiography system. Firstly, the radiographic theory and the related formulas were explained. Then the formula was deduced, the influence factors of the blackness were analyzed and refined, and the data collection was analyzed , A simple planning of the experimental scheme design of the influencing factor is carried out, and then the application and maintenance of the blackness function are described. Finally, the insufficiency and prospect of its application are forecasted.
