射线照相的几何因素

Geometrical Factors for photos by Radioactive Rays

射线照相的几何条件是影响照相质量的重要因素。本文介绍了透照厚度比、几何不清晰度、几何形状系数、影象宽度这几个几何参量的意义及其关系。

Geometrical conditions are important factors influencing the quality of photos by radioactive rays. This paper presents the meaning of geometrical conditions such as: the ratio of transparent thickness, geometrical turbidity index of geometrical shape and broad of figure, and their relations to the quality of photos by radioactive rays.
