The imaging performance of a phosphor-coated CCD system for mammography application is evaluated. The coated CCD is obtained by direct deposition of a Gd2O2S:Eu powder onto a detector surface. Modulation transfer function, noise power spectrum, and detective quantum efficiency are measured. Their dependence on the input beam X-ray energy is discussed. Images of a test phantom for mammography are compared with those obtained with a screen-film combination.

Abstract

The imaging performance of a phosphor-coated CCD system for mammography application is evaluated. The coated CCD is obtained by direct deposition of a Gd2O2S:Eu powder onto a detector surface. Modulation transfer function, noise power spectrum, and detective quantum efficiency are measured. Their dependence on the input beam X-ray energy is discussed. Images of a test phantom for mammography are compared with those obtained with a screen-film combination.
