X-Ray Phase-Contrast Imaging at PETRA III — •Alexander Hipp, Julia Herzen, Pavel Lytaev, Thomas Dose, Felix Beckmann, and Andreas Schreyer — Helmholtz-Zentrum Geesthacht, Geesthacht, Germany

Conventional absorption-based imaging often is lacking in good contrast at special applications like visualisation of soft tissue or weak absorbing material in general. To overcome this limitation, several new X-ray phase-contrast imaging methods have been developed at synchrotron radiation facilities. Our aim was to establish the possibility of different phase-contrast imaging modalities at the Imaging Beamline (IBL) and the High Energy Material Science Bemaline (HEMS) at Petra III. Here we present the instrumentation and the status of the currently successfully established phase-contrast imaging techniques. First results from measurements of biomedical samples will be presented to demonstrate the currently available range of applications at those two beam lines.
