3D analysis of enamel demineralisation in human dental caries using high-resolution, large field of view synchrotron X-ray micro-computed tomography

X-ray micro-computed tomography

Micro-computed tomography (μCT) has been successfully used to study the cardiovascular system of mouse embryos in situ. With the use of barium as a suitablecontrast agent, blood vessels have beenimaged and analysed quantitatively such asblood volume and vessel sizes on embryosof ages 14.5 to 16.5 days old. The advantageof using this imaging modality is that it hasprovide...

Observation of embolism formation and spreading in plants using synchrotron based X-ray micro computed tomography

High-resolution X-ray computed tomography of impactites

[1] High-resolution X-ray computed tomography (HRXCT) is a nondestructive method used to study the interiors of opaque solid objects. Here we present the results of a first application of the HRXCT method to imaging the interior of impactites, in particular, suevites (glass-bearing impact breccias) from the Bosumtwi (Ghana) and Ries (Germany) craters and a Muong Nong–type tektite from Thailand....

Quantification of eggshell microstructure using X-ray micro computed tomography

1. X-ray microcomputed tomography can be used to produce rapid, fully analysable, three-dimensional images of biological and other materials without the need for complex or tedious sample preparation and sectioning. We describe the use of this technique to visualise and analyse the microstructure of fragments of shell taken from three regions of chicken eggs (sharp pole, blunt pole and equatori...

Analysis of Rock Microstructure Using High- Resolution X-ray Tomography

In previous work we have described and validated robust techniques for partitioning the pore space of a porous material into simple regions, thereby allowing it to be represented by a network of simple building blocks. The primary purpose of this analysis is the generation of a pore-throat network for modelling immiscible multi-phase fluid displacements. However, combining our partitioning algo...
