摘要：
Monoenergetic X-ray beams are being utilized to examine the image information transfer properties of X-ray intensifying screens conventionally used in screen-film imaging systems. The technique of single photon counting is being employed to determine the relative probability distribution of the number of optical photons emitted from the screen after absorption of an incident X-Ray. These data can be used to determine the average number of light quanta emitted per absorbed X-ray. Results of these measurements for a typical calcium tungstate screen and one of the new rare-earth phosphor screens are presented.
