Experiments were conducted using highly collimated monochromatic X-rays at 20 keV, produced at the National Synchrotron Light Source. This study characterized digital detectors being considered for integration into a synchrotron-based diffraction enhanced imaging (DEI) apparatus used for medical imaging research, particularly mammography. These detectors are also being considered for integration into a proposed clinical prototype for DEI-based mammography. While all three systems had comparable image quality, the CCDs had faster readout time than the image plate system. However, the Fuji system had the largest dynamic range (∼10 5 compared to 10 4 for CCDs) and the largest active area. The MicroPhotonics XQUIS 1000 had the best spatial resolution as characterized by the point spread function.}, number={1-2}, journal={NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT}, author={Kiss, MZ and Sayers, DE and Zhong, Z}, year={2002}, month={Sep}, pages={280–290} } @article{pisano_johnston_chapman_geradts_iacocca_livasy_washburn_sayers_zhong_kiss_et al._2000, title={Human breast cancer specimens: Diffraction-enhance imaging with histologic correlation - Improved conspicuity of lesion detail compared with digital radiography}, volume={214}, ISSN={["0033-8419"]}, DOI={10.1148/radiology.214.3.r00mr26895}, abstractNote={Seven breast cancer specimens were examined with diffraction-enhanced imaging at 18 keV with a silicon crystal with use of the silicon 333 reflection in Bragg mode.
