Purpose Refraction contrast due to x-ray refraction,has been proved to be good at depicting objects that consist of matter with weak x-ray absorption by many researchers.Besides,some researchers have reported the studies on the image contrast due to ultra-small x-ray scatter(USAXS) using Bragg case analyzer and shown the utility of the contrast using phantoms that exhibit strong USAXS.The purpose of this study is to try to a simplified USAXS imaging to a breast cancer specimen excised during mastectomy.
