Propagation-based X-ray phase contrast enables nanoscale imaging of biological tissue by
probing not only the attenuation but also the real part of the refractive index of the sample …

Coherent wave-propagation in the near-field Fresnel-regime is the underlying contrast-
mechanism to (propagation-based) x-ray phase contrast imaging (XPCI), an emerging …

X-ray phase contrast imaging based on free space propagation relies on phase retrieval to
obtain sharp images of micro-and nanoscale objects, with widespread applications in …

Like many other advanced imaging methods, x-ray phase contrast imaging and tomography
require mathematical inversion of the observed data to obtain real-space information. While …

State-of-the-art techniques for phase retrieval in propagation based X-ray phase-contrast
imaging are aiming to solve an underdetermined linear system of equations. They …

We introduce theoretically and demonstrate experimentally a contrast transfer function
based phase retrieval algorithm that reconstructs the projected thickness of an …

X-ray phase-contrast imaging is a technique that aims to reconstruct the projected
absorption and refractive index distributions of an object. One common feature of …

Promoted by the advent of coherent synchrotron light sources, phase contrast tomography
allows to resolve three-dimensional variations of an unknown sample's complex refractive …

X-ray propagation-based phase-contrast imaging is an attractive phase-sensitive imaging
technique that has found applications in many research fields. Here, we report the …

We present a method for phase retrieval in propagation-based x-ray imaging, based on the
contrast transfer and transport of intensity equation approaches. We show that the contrast …
