Abstract
The imaging properties of the phosphor layer in fluorescent screens or image intensifiers are related to its X-ray absorption characteristics. Monte Carlo methods were applied for the simulation of X-ray photon diffusion in a phosphor layer. The K-reabsorption factor, absorbed X-ray energy, quantum absorption efficiency, statistical factor and noise-equivalent absorption were determined as a function of the incident energy and angle of the X rays for 8 commonly used phosphor layer. These basic physical quantities will be useful for the prediction of the information transfer properties of a phosphor layer.This publication has 1 reference indexed in Scilit:
