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…
Material identification using laboratory X-ray beam tracking: quantitativeness and signal-to-noise ratio requirements
Sumera Rehman, Ashkan Ajeer, Connor Darling +3
Simultaneous structural and elemental characterisation of a specimen in a non-destructive manner is an instrumental approach with applications in a variety of fields including ener…
Spatial resolution of X-ray beam-tracking microscopy
Harry Allan, Carlos Navarrete-León, Adam Doherty +3
X-ray beam-tracking is a phase-contrast imaging technique capable of simultaneously retrieving transmission, phase, and dark-field images. Although the spatial resolution in beam-t…
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…
Dynamic laboratory X-ray phase-contrast microtomography with structure-based prior regularisation
Harry Allan, Tom Partridge, Joseph Jacob +1
X-ray microtomography is a versatile tool allowing the measurement of the 3D structure of optically thick samples. As a non-destructive technique, it is readily adapted to 4D imagi…
Offset geometry for extended field-of-view in multi-contrast and multi-scale X-ray microtomography of lung cancer lobectomy specimens
Harry Allan, Adam Doherty, Carlos Navarrete-León +13
X-ray microtomography is a powerful non-destructive technique allowing 3D virtual histology of resected human tissue. The achievable imaging field-of-view, is however limited by th…
A laboratory-based X-ray phase contrast microscopy system for targeting in unstained soft-tissue samples
Michela Esposito, Nicole Schieber, Alessandro Olivo +2
We propose an imaging system and methodology for mapping soft-tissue samples in three dimensions, with micron-scale and isotropic spatial resolution, with low-concentrations as wel…
High angular sensitivity X-ray phase-contrast microtomography of soft-tissue through a two-directional beam-tracking synchrotron set-up
Carlos Navarrete-Leon, P. Stephen Patrick, Adam Doherty +8
Two-directional beam-tracking (2DBT) is a method for phase-contrast imaging and tomography that uses an intensity modulator to structure the X-ray beam into an array of independent…
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…
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…
Accelerated iterative tomographic reconstruction with x-ray edge illumination
Peter Modregger, Tomasz Korzec, Jeff Meganck +3
Compared to standard tomographic reconstruction, iterative approaches offer the possibility to account for extraneous experimental influences, which allows for a suppression of rel…
Neutron Dark-Field Imaging with Edge Illumination
Marco Endrizzi, Gibril K. Kallon, Triestino Minniti +2
We report on an Edge Illumination setup enabling neutron dark-field imaging where two amplitude modulators are used to structure and subsequently analyze the neutron beam. The modu…
Detector requirements for single mask edge illumination x-ray phase contrast imaging applications
G. K. Kallon, F. A. Vittoria, M. Endrizzi +5
Edge illumination (EI) is a non-interferometric X-ray phase contrast imaging (XPCI) method that has been successfully implemented with conventional polychromatic sources, thanks to…
X-ray phase-contrast radiography and tomography with a multi-aperture analyser
M. Endrizzi, F. A. Vittoria, L. Rigon +2
We present a multi-aperture analyser set-up for performing X-ray phase contrast imaging in planar and three-dimensional modalities. A multi-slice representation of the sample is us…
