Abstract
The imaging performance of a phosphor-coated CCD system for mammograph y application is evaluated. The coated CCD is obtained by direct depos ition of a Gd2O2S:Eu powder onto a detector surface. Modulation transf er function, noise power spectrum, and detective quantum efficiency ar e measured. Their dependence on the input beam X-ray energy is discuss ed. Images of a test phantom for mammography are compared with those o btained with a screen-film combination.
