摘要

为了探讨X射线衍射增强成像的衬度与X射线能量的关系

利用北京同步辐射光源4W1A光束线引出的硬X射线对大块正常和癌变的乳腺组织进行成像研究。在摇摆曲线顶部位置获得的图像（峰位图像）和表观吸收图像的衬度随X射线能量的变化关系是相似的

说明峰位图像和表观吸收图像包含的主要衬度相似

即吸收衬度

而折射图像的衬度随X射线能量的增大总体上呈现下降趋势。综合来看

对于乳腺类的软组织来说

DEI成像在低能量端有很好的衬度

反映了衍射增强成像更适合于主要由轻元素组成的物体的成像。

Abstract

For discussing the relation between the contrast of X-ray diffraction enhanced imaging (DEI) and the energy of X-rays

the massive samples of breast tissue including normal and cancerous were studied with the DEI method using the hard X-rays from 4W1A beamline at the Beijing Synchrotron Radiation Facility (BSRF). The results show that the contrasts of the peak-position image or apparent absorption image keep unchanged when different X-ray energies are used. The contrast of refraction image trends to be weakened when the X-ray energy is increased. As a result

it seems the DEI method is fit to image objects made of light elements.
