Integration of Digital Detectors into a Diffraction Enhanced Imaging System
Abstract
Images of calcifications embedded in breast tissue specimens have been obtained using a synchrotron based diffraction enhanced imaging (DEI) system and subsequently compared to images obtained using synchrotron-based radiography. Of the three specimens imaged, two contained calcifications associated with breast cancer and one was benign. The samples were imaged using 18 kev synchrotron radiation at the National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory. The DEI images were obtained by placing a Silicon analyzer crystal tuned to the 333 plane in the beam path between the sample and the detector. Contrast of the calcifications is consistently higher in the DEI images when compared to the normal radiographs. This comparison, called the gain value, is the ratio of the peak contrast (or refraction contrast) to the conventional radiographic contrast. In all three specimens the gain values were consistently larger than one, indicating that image contrast using DEI is much higher than from conventional synchrotron-based radiography.
