Multifractal Analysis of Reservoir Rock Samples Using 3D X-Ray Micro Computed Tomography Images

open access: yesIEEE Access, 2022
Characterizing heterogeneity in reservoir rocks at the pore scale is crucial to understand the flow patterns better, and estimate reservoir petrophysical properties such as porosity and permeability. This study introduces multifractals as descriptors for

Photoacoustic computed tomography guided microrobots for targeted navigation in intestines in vivo [PDF]

open access: yes, 2020
Tremendous progress in synthetic micro/nanomotors has been made for potential biomedical applications. However, existing micro/nanomotor platforms are inefficient for deep tissue imaging and motion control in vivo.

Prospective Respiratory Gated Carbon Nanotube Micro Computed Tomography

open access: yesAcademic Radiology, 2011
Challenges remain in the imaging of the lungs of free-breathing mice. Though computed tomography (CT) is near optimal from a contrast perspective, the rapid respiration rate, limited temporal resolution and inflexible x-ray pulse control of most micro-CT (mCT) scanners limits their utility in pulmonary imaging.

High-resolution computed tomography reconstructions of invertebrate burrow systems [PDF]

open access: yes, 2015
The architecture of biogenic structures can be highly influential in determining species contributions to major soil and sediment processes, but detailed 3-D characterisations are rare and descriptors of form and complexity are lacking.

An Investigation of the Mechanical and Physical Characteristics of Cement Paste Incorporating Different Air Entraining Agents using X-ray Micro-Computed Tomography [PDF]

open access: yes, 2020
Improving the thermal insulation properties of cement-based materials is the key to reducing energy loss and consumption in buildings. Lightweight cement-based composites can be used efficiently for this purpose, as a structural material with load ...

High spectral and spatial resolution X-ray transmission radiography and tomography using a Color X-ray Camera [PDF]

open access: yes, 2014
High resolution X-ray radiography and computed tomography are excellent techniques for non-destructive characterization of an object under investigation at a spatial resolution in the micrometer range.

Gas flow in near surface comet like porous structures: Application to 67P/Churyumov-Gerasimenko [PDF]

open access: yes, 2018
We performed an investigation of a comet like porous surface to study how sub-surface sublimation with subsequent flow through the porous medium can lead to higher gas temperatures at the surface.

X-ray Micro Computed Tomography (MicroCT) v1

open access: yes, 2022
This protocol has been successfully used with colonial tunicates. It has been adapted to our needs based on the following publication: " MicroCT for comparative morphology: simple staining methods allow high-contrast 3D imaging of diverse non-mineralized animal tissues " by Brian D Metscher. MicroCT for comparative morphology: simple staining methods

Detection of trabecular bone microdamage by micro-computed tomography [PDF]

open access: yesJournal of Biomechanics, 2007
Microdamage is an important component of bone quality and affects bone remodeling. Improved techniques to assess microdamage without the need for histological sectioning would provide insight into the role of microdamage in trabecular bone strength by allowing the spatial distribution of damage within the trabecular microstructure to be measured ...
