The new X-ray radiography imaging technique, named diffraction enhanced imaging (DEI), enables almost scatter free absorption imaging, the production of the so-called refraction images of a sample. The images show improved contrast compared to standard imaging applications. At the HASYLAB wiggler beamline W2 at the 2nd-generation storage ring DORIS a 5cm wide beam with an adjustable energy between 10 and 70keV is available. A Si [111] pre-monochromator is used followed by the main monochromator using the (111) or the (333)-reflection. Visualization of fossils, detecting internal pearl structures, monitoring of bone and cartilage and documentation of implant healing in bone are application examples at HASYLAB. © 2004 American Institute of Physics [ABSTRACT FROM AUTHOR]
