Exploration of Monoenergetic X-Ray Mammography with Syncrotron Radiation.
Abstract
The x-ray emission from a synchrotron provides the capability of obtaining high photon fluxes, selectable monoenergetic x-ray beams and a nearly ideal narrow beam geometry. Thus, the synchrotron provides the ideal x-ray imaging source to explore technique% for imaging soft tissues such as the breast. Under this grant we have developed a new imaging technique which we call Diffraction Enhanced x-ray Imaging (DEI). This technique has the potential to dramatically change mammography and radiography in general. Specifically developed as part of our x-ray mammography program utilizing monochromatic x-rays from a synchrotron source, this technique has produced images of test objects and tissue whose contrast and information content far exceeds conventional techniques. Preliminary work with human breast cancer specimens suggests that DEI images include information regarding specific physical characteristics of the lesion including border detail and associated features that are not detected by conventional imaging.
