Imaging Characteristics of a Direct Conversion Full-Field Digital Mammography Detector using Seleniuaphy x-ray generator with HTC. x-ray scatter rejection grid. Modulation transfer function, MTF, approximates theoretical limits for the 70 µ pitch DirectRay. array. Detective quantum efficiency, DQE, approaches the ~70% theoretical maximum at zero-frequency for normal mammography x-ray exposure, and
