Porosity formation during atmospheric ice accretion: measurements using micro-computed tomography

Investigating porosity of sintering porous copper structure with 3D micro-focus X-ray computed tomography (μCT)

Purpose: The paper presents studies on the structure intended to form a heat exchange element made of sintered porous Cu. Design/methodology/approach: Analyses of Cu foam exhibiting a cellular structure have been carried out using X-ray tomography. Findings: Samples of copper foam have been imaged at high resolution using a large-field, 3D micro-focus X-ray computed tomography (μCT) system, thr...

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...

Computed Tomography to Estimate the Representative Elementary Area for Soil Porosity Measurements

Computed tomography (CT) is a technique that provides images of different solid and porous materials. CT could be an ideal tool to study representative sizes of soil samples because of the noninvasive characteristic of this technique. The scrutiny of such representative elementary sizes (RESs) has been the target of attention of many researchers related to soil physics field owing to the strong...

accuracy of linear measurements using cone beam computed tomography in comparison with clinical measurements

objectives: this study sought to evaluate the accuracy and errors of linear measurements of mesiodistal dimensions of kennedy class iii edentulous space using cone beam computed tomography (cbct) in comparison with clinical measurements. materials and methods: nineteen kennedy class iii dental arches were evaluated. an impression was made of each dental arch and poured with dental stone. the di...
