Unlike conventional x-ray attenuation one of the advantages of phase contrast x-ray imaging
is its capability of extracting useful physical properties of the sample. In particular the …

Purpose: Biological soft tissues encountered in clinical and preclinical imaging mainly
consists of atoms of light elements with low atomic numbers and their elemental composition …

In recent years, increasing attention has been devoted to X-ray phase contrast imaging,
since it can provide high-contrast images by using phase variations. Among the different …

We examine the projection approximation in the context of propagation-based phase
contrast imaging using hard x-rays. Specifically, we consider the case of a cylinder or a …

In this chapter, the physical and mathematical principles of X-ray computed tomography are
summarised. First, the fundamentals of X-ray physics are covered, with details on …

This review provides a brief overview, albeit from a somewhat personal perspective, of the
evolution and key features of various hard X-ray phase-contrast imaging (PCI) methods of …

In the case of single-distance propagation-based phase-contrast X-ray computed
tomography with synchrotron radiation, the conventional reconstruction pipeline includes an …

Refractive index gradients in materials or at material interfaces lead to x-ray diffraction.
Interference of this radiation with adjacent x-ray waves causes phase contrast that can be …

We present an x-ray phase contrast imaging method based on coded apertures sensitive to
phase effects in two directions simultaneously. To date, this is the only non-free-space …

A different x-ray phase contrast imaging technique based on the combination of structured
illumination and an optimized hybrid input-output algorithm for phase and amplitude …
