Over the last decade different phase contrast approaches have been exploited at the
medical beamline SYRMEP of the synchrotron radiation facility Elettra in Trieste, Italy. In particular
special focus has been drawn to analyzer based imaging and the associated imaging theory
and processing. Analyzer based Imaging (ABI) and Diffraction Enhanced Imaging (DEI) techniques
have been successfully applied in several biomedical applications. Recently it has been suggested
to translate the acquired knowledge in this field towards a Thomson Backscattering Source
(TBS), which is presently under development at the Frascati National Laboratories of INFN (Istituto
Nazionale di Fisica Nucleare) in Rome, Italy. Such source is capable of producing intense and
quasi-monochromatic hard X-ray beams. For the technical implementation of biomedical phase
imaging at the TBS a grating interferometer for differential phase contrast imaging has been designed
and successfully tested at SYRMEP beamline.
