A theoretical analysis of the in-line method of x-ray phase-contrast imaging with a small
(microfocus) source is presented. By applying the stationary-phase formula to the Fresnel …

A well‐known problem in x‐ray microcomputed tomography is low sensitivity. Phase contrast
imaging offers an increase of sensitivity of up to a factor of in the hard x‐ray region, which …

We present a quantitative, non-interferometric, X-ray differential phase contrast imaging
technique based on the edge illumination principle. We derive a novel phase retrieval …

Simple analytical expressions are derived for the spatial resolution, contrast and signal-to-
noise in X-ray projection images of a generic phase edge. The obtained expressions take …

We discuss contrast formation in a propagating x-ray beam. We consider the validity
conditions for linear relations based on the transport-of-intensity equation (TIE) and on …

We recently demonstrated how quantitative X-ray phase contrast imaging may be performed
with laboratory sources using the coded aperture technique. This technique required the …

General principles and results for the optimization of the performance of x-ray in-line phase-
contrast imaging systems for spatially incoherent sources are investigated. In particular …

A method is proposed which enables the retrieval of the thickness or of the projected
electron density of a sample from a single input image acquired with an edge illumination …

The attenuation of x-rays in a material forms the basis of x-ray radiography and tomography.
By measuring the transmission of the x-rays over a large amount of raypaths, the three …

The in-line phase-contrast imaging has great potential for clinical imaging applications. This
work presents a general theoretical formalism for the in-line phase-contrast imaging. The …
