High resolution phase contrast radiography: A comparison between propagation-based and grating-based imaging — •Max Schuster, Michael Gallersdörfer, Veronika Ludwig, Jens Rieger, Maria Seifert, Andreas Wolf, Georg Pelzer, Thilo Michel, Gisela Anton, and Stefan Funk — ECAP - Erlangen Centre for Astroparticle Physics, Universität Erlangen-Nürnberg, Erwin-Rommel-Str. 1, 91058 Erlangen

In addition to the attenuation of an X-ray wave both propagation- and grating-based X-ray phase contrast imaging (PCI) enable the reconstruction of its phase shift imprinted by the interaction with matter. This offers sensitivity to local variations in the electron density distribution and thus provides improved contrast for soft tissue imaging.

High spatial resolution measurements were performed using propagation-based PCI [1,2]. Compared to this, grating-based PCI promises better sensitivity to small variations in the densities [3].

In this contribution we will present a comparison between propagation- and grating-based PCI with regard to their requirements on the experimental setup and to their potential for future applications in the field of bio-medical imaging.
