- 0 - RADIOGRAPHIC SCREEN/FILM ASSEMBLIES WITH IMPROVED DETECTION QUANTUM EFFICIENCIES Abstract of the Disclosure Assemblies of double coated radiographic elements exhibiting sharply curtailed crossover and front and back intensifying screen pairs are disclosed. By choosing a front screen that exceeds a stated sharpness criterion, expressed in terms of modulation transfer factors (MTF), and a back screen and adjacent emulsion layer unit combination exhibiting a photicity at least twice that of the combination of the front screen and its adjacent emulsion layer unit an enhancement in detective quantum efficiency (DQE) is realized.
