A filmkcreen system is described where the light emission of the intensifying screen is in the ultraviolet (w), which is more efficiently absorbed by lhe film, and hence print-through is vinualiy eliminated. In addition, because of significantly higher uv absorption within the screen, the modulation lransfer function (Mm) is superior to that of conventional systems based on visible light. Thus the overall uv fildscreen system has superior imaging efficiency and quality, as measured by the detective quantum efficiency (WE) and the noise equivalent quantum efficiency (NEQ)), to those of conventional systems, These imaging chancteristics of the novel systems are described here and are compared with those of some conventional systems,
