This article discusses two experimental setups of edge illumination (EI) x-ray phase contrast imaging (XPCi) as well as
the theory that is required to reconstruct quantitative tomographic maps using established methods, e.g. filtered back
projection (FBP). Tomographic EI XPCi provides the option to reconstruct volumetric maps of different physical
quantities, amongst which are the refractive index decrement from unity and the absorption coefficient, which can be
used for dual-mode imaging. EI XPCi scans of a custom-built wire phantom using synchrotron and x-ray tube generated
radiation were carried out, and tomographic maps of both parameters were reconstructed. This article further discusses
the theoretical basis for the tomographic reconstruction of images showing combined phase and attenuation contrast.
Corresponding experimental results are presented.
