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…
