Diffraction enhanced imaging is a new x-ray radiographic imaging modality using monochromatic x-rays from a synchrotron which produces images of thick absorbing objects that are almost completely free of scatter. They show dramatically improved contrast over standard imaging applied to the same phantom. The contrast is based not only on attenuation but also the refraction and diffraction properties of the sample. This imaging method may improve image quality for medical applications, industrial radiography for non-destructive testing and x-ray computed tomography.
衍射增强成像(Diffraction enhanced imaging)是一种新的X射线放射成像方式,它使用来自同步加速器的单色X射线,能够生成几乎完全无散射的厚吸收物体的图像。与应用于同一模型的标准成像相比,它们的对比度有显著提高。这种对比度不仅基于衰减,还基于样品的折射和衍射特性。这种成像方法可能会提高医学应用、工业无损检测射线照相和X射线计算机断层扫描的图像质量。
