Universal Phase Contrast in Micro-CT Systems
Grammatiki Lioliou, Alberto Astolfo, Marco Endrizzi +3
Conventional high-resolution micro-CT systems are regarded as attenuation-based unless visible Fresnel fringes reveal the presence of propagation-based phase contrast. Here we show…
Quantitative phase nano-imaging with a laboratory source
Luca Fardin, Chris Armstrong, Alberto Astolfo +8
Investigating the structure of matter at the nanoscale non destructively is a key capability enabled by X-ray imaging. One of the most powerful nano-imaging methods is X-ray ptycho…
Microfluidic gratings for X-ray Phase Contrast Imaging
Alessandro Rossi, Francesco Coccimiglio, Antonio Ferraro +8
Fabrication of X-ray gratings has surged in the last two decades thanks to their vast employment in X-ray Phase Contrast Imaging, an imaging technique able to boost X-ray sensitivi…
Laboratory-based x-ray microtomography with directional dark-field sensitivity
Carlos Navarrete-Leon, Alvaro Jose Gonzalez-Grajales, Harry Allan +9
We demonstrate dark-field x-ray microtomography in a compact, laboratory-based system capable of resolving attenuation, phase, and anisotropic scattering signals with micrometer-sc…
Fabrication of Ultra-Thick Masks for X-ray Phase Contrast Imaging at Higher Energy
Alessandro Rossi, Ian Buchanan, Alberto Astolfo +6
X-ray phase contrast imaging (XPCI) provides higher sensitivity to contrast between low absorbing objects that can be invisible to conventional attenuation-based X-ray imaging. XPC…
Multi-contrast x-ray identification of inhomogeneous materials and their discrimination through deep learning approaches
Thomas Partridge, Sukrit S. Shankar, Ian Buchanan +4
Recent innovations in x-ray technology (namely phase-based and energy-resolved imaging) offer unprecedented opportunities for material discrimination, however they are often used i…
Single-shot X-ray Dark-field Tomography
Adam Doherty, Ian Buchanan, Alberto Astolfo +5
X-ray dark-field imaging creates a representation of the sample where contrast is generated by subresolution features within the volume under inspection. These are detected by a lo…
Direct x-ray scattering signal measurements in edge-illumination/beam-tracking imaging and their interplay with the variance of the refraction signals
Ian Buchanan, Silvia Cipiccia, Carlo Peiffer +11
X-ray dark-field or ultra-small angle scatter imaging has become increasingly important since the introduction of phase-based x-ray imaging and is having transformative impact in f…
Increased material differentiation through multi-contrast x-ray imaging: a preliminary evaluation of potential applications to the detection of threat materials
A. Astolfo, I. G. Haig, D. Bate +2
Most material discrimination in security inspections is based on dual-energy x-ray imaging, which enables the determination of a material's effective atomic number (Zeff) as well a…
X-ray phase-contrast micro tomography of soft tissues using a compact laboratory system with two-directional sensitivity
Carlos Navarrete-Leon, Adam Doherty, Savvas Savvidis +8
X-ray micro tomography is a non-destructive, three-dimensional inspection technique applied across a vast range of fields and disciplines, ranging from research to industrial, enco…
