Recent developments on techniques for differential phase imaging at the medical beamline of ELETTRA

摘要

Over the last decade different phase contrast approaches have been exploited at themedical beamline SYRMEP of the synchrotron radiation facility Elettra in Trieste, Italy. In particularspecial focus has been drawn to analyzer based imaging and the associated imaging theoryand processing. Analyzer based Imaging (ABI) and Diffraction Enhanced Imaging (DEI) techniqueshave been successfully applied in several biomedical applications. Recently it has been suggestedto 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 (IstitutoNazionale di Fisica Nucleare) in Rome, Italy. Such source is capable of producing intense andquasi-monochromatic hard X-ray beams. For the technical implementation of biomedical phaseimaging at the TBS a grating interferometer for differential phase contrast imaging has been designedand successfully tested at SYRMEP beamline.
