Exploration of Monoenergetic X-Ray Mammography with Syncrotron Radiation
Abstract
The purpose of this research is to explore the potential advantages of monoenergetic x-rays in medical imaging especially mammography. We are using synchrotron radiation as our source of x-rays to provide monoenergetic beams from 16 ke V upward. We are also developing Monte Carlo techniques to calculate contrast images. To date we have demonstrated an increase in contrast in phantoms and tissue samples over that obtained with conventional x-ray machines. We are developing a Monte Carlo based 2D image model with better documentation of the scatter that can display the image from which image contrast can be calculated. We have also initiated exploration of refraction imaging and diffraction enhancement imaging that can be obtained by "analyzing" the emerging beam from target phantoms. This imaging technique promises to offer a new concept in medical imaging that could improve contrast more than an order of magnitude.
