Paper Abstract

Information transfer in a screen-film system occurs over a limited region of x-ray exposures because of the non-linear response of film to light emitted from the x-ray fluorescent screen. Based on screen light emission and film response data, the information transfer efficiency of a typical screen-film system is determined as a function of x-ray exposure for different x-ray energies. The method of determining this transfer efficiency is described, and the x-ray exposure regions over which information transfer can occur with this system is delineated for different x-ray energies.
