Line-Source Based X-Ray Tomography [PDF]

open access: yesInternational Journal of Biomedical Imaging, 2009
Current computed tomography (CT) scanners, including micro-CT scanners, utilize a point x-ray source. As we target higher and higher spatial resolutions, the reduced x-ray focal spot size limits the temporal and contrast resolutions achievable.

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.

Characterization of Pharmaceutical Tablets by X-ray Tomography

open access: yesPharmaceuticals, 2023
Solid dosage forms such as tablets are extensively used in drug administration for their simplicity and large-scale manufacturing capabilities. High-resolution X-ray tomography is one of the most valuable non-destructive techniques to investigate the ...

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 ...

Association between anticoagulation strategy and quality of life in chronic hemodialysis patients

open access: yesScientific Reports, 2023
Prevention of clotting in hemodialysis (HD) is a concern, but tools to monitor anticoagulation strategies as well as data on bleeding and its impact on quality of life (QoL) are scant.

Exploration of the X-ray Dark-Field Signal in Mineral Building Materials

open access: yesJournal of Imaging, 2022
Mineral building materials suffer from weathering processes such as salt efflorescence, freeze–thaw cycling, and microbial colonization. All of these processes are linked to water (liquid and vapor) in the pore space. The degree of damage following these

Quantitative X-ray tomography [PDF]

open access: yesInternational Materials Reviews, 2013
X-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. Our review considers first the image acquisition process, including the use of iterative
