Radiological Evaluation of DEI Breast Specimen Imaging

Abstract

The specific aims of this proposal are to determine the acquisition parameter values for obtaining the best DEI images for breast imaging. There are numerous parameter values for collection of DEI images and design specifications of a compact source for breast imaging depend upon what these values are. During the first year of this grant, we have acquired images of three tissue specimens at all the above parameter values except at Si(5,5,5). We have pathology assessments of the tissue samples and have identified 10 regions of interest for the readers to evaluate. We have the image processing algorithms ready for use including PLAHE, a new version of CLAHE (contrast limited adaptive histogram equalization). We have downloaded all the synchrotron images to our lab at UNC and have finished reformating them for display on our systems. An observer study is proposed and will begin within the next three months which will allow expert radiologists to score DEI images obtained with different acquisition parameter values. From this study, we can determine the optimal design specifications for a clinically useful breast imaging system.
