X-ray Fluorescence Computed Tomography (XFCT) Imaging with a Superfine Pencil Beam X-ray Source
Photonics, 2021 X-ray fluorescence computed tomography (XFCT) is a molecular imaging technique that can be used to sense different elements or nanoparticle (NP) agents inside deep samples or tissues. However, XFCT has not been a popular molecular imaging tool because it

Interlaced X-ray diffraction computed tomography [PDF]
Journal of Applied Crystallography, 2016 An X-ray diffraction computed tomography data-collection strategy that allows, post experiment, a choice between temporal and spatial resolution is reported. This strategy enables time-resolved studies on comparatively short timescales, or alternatively allows for improved spatial resolution if the system under study, or components within it, appear to

In situ 3D characterization of fatigue cracks displacement fields [PDF]
Fracture and Structural Integrity, 2013 The three dimensional growth of fatigue cracks in samples of nodular graphite cast iron is characterized using laboratory X-ray computed tomography. The cracks grow from laser machined artificial defects, their development is monitored in situ using ...

Adaptive zooming in X-ray computed tomography [PDF]
Journal of X-Ray Science and Technology: Clinical Applications of Diagnosis and Therapeutics, 2014 BACKGROUND: In computed tomography (CT), the source-detector system commonly rotates around the object in a circular trajectory. Such a trajectory does not allow to exploit a detector fully when scanning elongated objects. OBJECTIVE: Increase the spatial resolution of the reconstructed image by optimal zooming during scanning.

Effects of X-Ray Dose On Rhizosphere Studies Using X-Ray Computed Tomography.
PLoS ONE, 2013 X-ray Computed Tomography (CT) is a non-destructive imaging technique originally designed for diagnostic medicine, which was adopted for rhizosphere and soil science applications in the early 1980s.
