Abstract
It has been demonstrated in many instances that phase-based computed tomography (CT) can provide superior contrast-to-noise ratio for weakly attenuating samples than attenuation-based CT. In order to exploit this benefit on a wider scale, phase-based tomography implementations must be compatible with standard x-ray equipment. The edge illumination method, which is based on aperturing a beam and measuring spatial displacements caused by refraction, is an attractive choice for such use due to its low requirements on spatial and temporal coherence. This document provides a brief introduction to the working principle of the edge illumination method and reviews recent advances that lead to increased robustness, faster acquisitions and lower dose delivery. Moreover, it reports on a recent study in which the edge illumination method was applied to samples from the field of tissue engineering, yielding synchrotron-like image quality with exclusively commercially available, laboratory-based x-ray equipment.
