摘要：

Conventional absorption-based imaging often lacks in good contrast at special applications like visualization of soft tissue or weak absorbing material in general.(1) To overcome this limitation, several new X-ray phase-contrast imaging methods have been developed at synchrotron radiation facilities.(2,3) Our aim was to establish the possibility of different phase-contrast imaging modalities at the Imaging Beam line (IBL, P05) and the High Energy Material Science beamline (HEMS, P07) at Petra III (DESY, Germany). 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 as demonstration.
