Pressure profoundly alters all states of matter. The symbiotic development of ultrahigh-
pressure diamond anvil cells, to compress samples to sustainable multi-megabar pressures; …

We review the current X-ray techniques with 3D imaging capability at the nano-scale:
transmission X-ray microscopy, ptychography and in-line phase nano-tomography. We …

We present a method that enables performing x-ray phase-contrast imaging (XPCI)
computed tomography with a laboratory setup using a single image per projection angle …

We present a solution to the phase problem in near-field x-ray (propagation) imaging. The
three-dimensional complex-valued index of refraction is reconstructed from a set of …

X-ray propagation-based imaging techniques are well established at synchrotron radiation
and laboratory sources. However, most reconstruction algorithms for such image modalities …

We investigate the quantitative accuracy and noise sensitivity of reconstruction of the 3D
distribution of complex refractive index, n (r)= 1− δ (r)+ i β (r)⁠, in samples containing …

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 …

Synchrotrons have provided significant methods and instruments to study ancient materials
from cultural and natural heritages. New ways to visualise (surfacic or volumic) …

X-ray phase-contrast imaging techniques are used at synchrotron facilities to visualize tiny
density variations in bulk samples. They overcome the limitations of other non-destructive …

This paper investigates the 3D microscopic structure of ex-vivo human cardiac muscle.
Usual 3D imaging techniques such as DMRI or CT do not achieve the required resolution to …
