High temperature x-ray micro-tomography [PDF]
AIP Conference Proceedings, 2016 There is increasing demand for 3D micro-scale time-resolved imaging of samples in realistic - and in many cases extreme environments. The data is used to understand material response, validate and refine computational models which, in turn, can be used to reduce development time for new materials and processes.

Study of 20 Hz high spatial-temporal resolution monochromatic X-ray dynamic micro-CT
He jishu, 2023 BackgroundDynamic micro-computed tomography (micro-CT) using monochromatic X-ray offers higher density resolution and lower radiation damage compared to that using white X-ray, however balancing its imaging spatial and temporal resolution is challenging.

Study of the Microfocus X-Ray Tube Based on a Point-Like Target Used for Micro-Computed Tomography. [PDF]
PLoS ONE, 2016 For a micro-Computed Tomography (Micro-CT) system, the microfocus X-ray tube is an essential component because the spatial resolution of CT images, in theory, is mainly determined by the size and stability of the X-ray focal spot of the microfocus X-ray ...

X-ray computed micro-tomography of reticulated vitreous carbon [PDF]
Carbon, 2018 Abstract The 3D structure of various grades of reticulated vitreous carbon (RVC) is studied by X-ray computed micro-tomography (μCT). The settings required to estimate the bulk volumetric surface area, Ae, accurately are investigated and the results are compared to those obtained from scanning electron microscopy and from pressure drop measurements ...

X‐ray Stain Localization with Near‐Field Ptychographic Computed Tomography
Advanced Science, 2022 Although X‐ray contrast agents offer specific characteristics in terms of targeting and attenuation, their accumulation in the tissue on a cellular level is usually not known and difficult to access, as it requires high resolution and sensitivity.
