Abstract
A theoretical derivation for the point spread function (PSF) which describes the veiling glare in x-ray image intensifiers (II) is presented. The PSF is dependent on two parameters which can be determined experimentally for a given II. An experimental investigation of the linearity of veiling glare phenomenon is undertaken. The experimental results indicate that veiling glare could be described as a linear process to a high degree of accuracy.
摘要
本文给出了用于描述X射线图像增强器（II）中散射眩光的点扩散函数（PSF）的理论推导。PSF取决于两个参数，对于给定的图像增强器，可以通过实验确定这两个参数。对散射眩光现象的线性度进行了实验研究。实验结果表明，散射眩光在很大程度上可被描述为一个线性过程。
