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…

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…
