Abstract

The image information transfer properties of a number of x-ray fluorescent screens have been calculated for x-ray energies from 10 to 160 keV. The detective quantum efficiency of the screens at each x-ray energy has been determined by separate calculations of the x-ray absorption efficiency and the statistical factor associated with the emission of light photons upon absorption of an incident x ray. The point spread function of the screens at each x-ray energy has also been calculated. These basic physical quantities will be useful for the prediction of the information transfer properties of X-ray intensifying screens.
