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.
