Paper Abstract

Contrast in conventional imaging of soft tissues is often limited due to the very similar attenuation of tissues to be distinguished. Phase contrast techniques can enable discrimination of tissues with similar attenuation. A major limitation to the widespread adoption of phase-contrast techniques is that for tabletop sources the required degree of coherence generally requires a small (10 to 50 μm) source. In this work, a polycapillary optic was employed to create a small virtual source from a large spot rotating anode. Phase contrast images obtained with two optics and several pinholes have been analyzed and preliminary results obtained for quantitative phase measurements.
