Abstract
Edge illumination (EI) is an X-ray phase contrast imaging technique, exploiting sensitivity to X-ray refraction in order to visualize features which are often not detected by conventional, absorption-based radiography. The method does not require a high degree of spatial coherence and is achromatic, and can therefore be implemented with both synchrotron radiation and commercial X-ray tubes. Using different retrieval algorithms, information about an object’s attenuation, refraction and scattering properties can be obtained. In recent years, a theoretical framework has been developed that enables EI computed tomography (CT), and hence three dimensional imaging. This review provides a summary of these advances, covering the development of different image acquisition schemes, retrieval approaches and applications. These developments constitute an integral part in the transformation of EI CT into a widely spread imaging tool, for use in a range of fields.
