Diffraction Enhanced x-ray Imaging (DEI) derives contrast from absorption (as does conventional radiography), gradient in x-ray index of refraction and scatter-rejection (extinction). The combination of these contrast mechanisms generally allows more features in objects to be observed compared to conventional radiography [1]. In some instances or in specially prepared systems it is possible to ...
