Integration of Digital Detectors into a Diffraction Enhanced Imaging System
Abstract
Three x-ray detector systems - storage phosphor, a prototype CCD, and a production monel CCD were compared with respect to format, resolution, quantum efficiency, and systematics using synchrotron radiation in the range 15-40 keV. Overall, the CCDs performed faster than the storage phosphor and possessed higher quantum efficiencies. However, the storage phosphor had a superior spatial resolution (Modulation Transfer Function), and its larger format lends itself better to mammographic imaging than the smaller format CCDs. As a result of this comparison, criteria are being developed for selecting digital detection systems for the synchrotron-based diffraction enhanced imaging (DEI) system at the National Synchrotron Light Source, and for a clinical prototype for mammography using DEI.
