Changchun Hua,Liuliu Zhang,Xinping Guanations in uniform as well as structured background. Calcium carbonate grains of various sizes were used to simulate calcifications. Three detectors were studied: a 100 µm aSi:H/CsI(Tl) flat-panel system, a 30 µm CCD based system and an analog screen/film combination. The preliminary results show tha

A high resolution (25 µm) hybrid selenium/CCD slot scan detector for digital mammographyecially-designed CCDs (charge coupled devices) with a 25-µm pixel pitch. The detector element fill factor approaches 100%. We have produced and are testing CCD structures that utilize both surface and buried channel structures. We are developing selenium blocking layers that are optimized for electron signal transfer to a CCD.
