X-Ray Microtomography (μCT) Using Phase Contrast for the Investigation of Organic Matter

Abstract
We show that microtomography (µCT) using synchrotron radiation (SR) can be extended to include X-ray phase contrast, which is two to three orders of magnitude more sensitive than conventional attenuation contrast and better suited for the investigation of specimens consisting chiefly of light elements for photon energies ranging at least from 1 to 100 ke V
