X-ray computed tomography in life sciences [PDF]

open access: yesBMC Biology, 2020
Recent developments within micro-computed tomography (μCT) imaging have combined to extend our capacity to image tissue in three (3D) and four (4D) dimensions at micron and sub-micron spatial resolutions, opening the way for virtual histology, live cell ...

X-ray computed tomography [PDF]

open access: yesNature Reviews Methods Primers, 2021
X-ray computed tomography (CT) can reveal the internal details of objects in three dimensions non-destructively. In this Primer, we outline the basic principles of CT and describe the ways in which a CT scan can be acquired using X-ray tubes and synchrotron sources, including the different possible contrast modes that can be exploited.

Stereo X-Ray Tomography

open access: yesIEEE Transactions on Nuclear Science, 2023
X-ray tomography is a powerful volumetric imaging technique, but detailed three dimensional (3D) imaging requires the acquisition of a large number of individual X-ray images, which is time consuming. For applications where spatial information needs to be collected quickly, for example, when studying dynamic processes, standard X-ray tomography is ...

Quantitative X-ray tomography [PDF]

open access: yesInternational Materials Reviews, 2013
AbstractX-ray computer tomography (CT) is fast becoming an accepted tool within the materials science community for the acquisition of 3D images. Here the authors review the current state of the art as CT transforms from a qualitative diagnostic tool to a quantitative one.

Tunable X-ray dark-field imaging for sub-resolution feature size quantification in porous media

open access: yesScientific Reports, 2021
X-ray computed micro-tomography typically involves a trade-off between sample size and resolution, complicating the study at a micrometer scale of representative volumes of materials with broad feature size distributions (e.g. natural stones). X-ray dark-
