Diffraction-enhanced imaging is a recently developed X-ray imaging techniqu
e that has demonstrated enhanced contrast for dense, highly absorbing mater
ials of interest in materials science and medicine. The implementation of t
his technique in experiments at the National Synchrotron Light Source and a
t the Advanced Photon Source is described in detail. (C) 2000 Elsevier Scie
