The changes in phase contrast X-ray images as the photon energy is changed were observed and analyzed. Such results were justified in part with a preliminary model based on the interplay of refraction and absorption effects. The observed change may open up interesting opportunities for chemical analysis based on phase contrast images taken at different absorption edges.
