Impact of Photon Spectra on the Sensitivity of Polymer Gel Dosimetry by X-Ray Computed Tomography

Introduction: The purpose of the current study was to investigate the effect of X-ray spectra on the sensitivity of a polymer gel dosimeter imaged with a conventional computed tomography (CT) scanner. Material and Methods: The whole process of CT imaging of an irradiated polymer gel was simulated by MCNPX Monte Carlo (MC) code. The imaging of polyacrylamide gel was accomplished by means of a co...

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...

Quasi-static Indentation and Compression after Impact Damage Growth Monitoring Using Microfocus X-ray Computed Tomography

1 Introduction The susceptibility of carbon fibre-polymer matrix composites to low velocity impact damage has a direct effect on the residual in-plane compressive strength [1]. Whilst the general understanding of damage caused by impact and post-impact compression is understood from studying failed specimens, the damage evolution process is still not well understood. This is largely due to the ...

X-ray computed tomography.

X-ray computed tomography (CT), introduced into clinical practice in 1972, was the first of the modern slice-imaging modalities. To reconstruct images mathematically from measured data and to display and to archive them in digital form was a novelty then and is commonplace today. CT has shown a steady upward trend with respect to technology, performance and clinical use independent of predictio...

Validation of x-ray microfocus computed tomography as an imaging tool for porous structures.

X-ray microfocus computed tomography (micro-CT) is recently put forward to qualitatively and quantitatively characterize the internal structure of porous materials. However, it is known that artifacts such as the partial volume effect are inherently present in micro-CT images, thus resulting in a visualization error with respect to reality. This study proposes a validation protocol that in the ...
