X-ray phase-contrast imaging and tomography make use of the refraction of X-rays by the
sample in image formation. This provides considerable additional information in the image …

This revised and updated second edition–now with two new chapters-is the only book to
give a comprehensive overview of computer algorithms for image reconstruction. It covers …

A method of tomographic phase retrieval is developed for multi-material objects whose
components each has a distinct complex refractive index. The phase-retrieval algorithm …

We demonstrate interface-specific propagation-based x-ray phase retrieval tomography of
the thorax and brain of small animals. Our method utilizes a single propagation-based x-ray …

X-ray tomography is a powerful tool giving access to the morphology of biofilms, in 3D
porous media, at the mesoscale. Due to the high water content of biofilms, the attenuation …

Dual-energy x-ray imaging is a powerful tool enabling two-component samples to be
separated into their constituent objects from two-dimensional images. Phase contrast x-ray …

Propagation-based X-ray phase-contrast tomography (PCT) seeks to reconstruct information
regarding the complex-valued refractive index distribution of an object. In many applications …

Material decomposition in X-ray imaging uses the energy-dependence of attenuation to
digitally decompose an object into specific constituent materials, generally at the cost of …

The challenge of computed tomography is to reconstruct high-quality images from few-view
projections. Using a prior guidance image, guided image filtering smoothes images while …

We consider the reconstruction of a two-dimensional discrete image from a set of
tomographic measurements corresponding to the Radon projection. Assuming that the …
