The combined use of in-situ loading in an X-ray micro-CT system and advanced image processing techniques to unravel the mechanical behaviour and failure of porous materials. KU Leuven

The aim of this research is to find the relation between the morphology and mechanical behaviour and failure of the porous materials produced by rapid prototyping technique. For this purpose the combined use of micro-CT imaging, 3D image analysis and non-rigid image registration with in-situ mechanical loading will be applied. The changing morphology during loading and the strain distribution in the porous material will be investigated on the ...

Development of a framework for advanced processing of 4D dynamic X-ray micro-CT data, using integrated reconstruction and analysis methods Ghent University

Luc Van Hoorebeke
Department of Physics and astronomy

CT scans can be used to visualise 3D volumes in a non-destructive way. For fast dynamic processes these scans need to be performed fast. This has a negative impact on the quality. This project aims to improve the reconstruction quality and data analysis of 4D scans by incorporating prior knowledge in the reconstruction process and using existing spatio-temporal correlations.

In-situ characterization of drug release and dissolution processes in sustained-release solid dosage forms Ghent University

Chris Vervaet
Department of Pharmaceutics, Department of Physics and astronomy

In this project, the drug release process of sustained-release dosage forms will be in-situ monitored by dynamic visualization based on 4D-U+03BCCT. To achieve this, new developments in dynamic highresolution X-ray tomography (4D-U+03BCCT) will be made for both image acquisition and processing. This knowledge gained will enable to optimize drug formulations and their manufacturing process.

Novel methods and tools for in situ characterization of composite materials and tissues, and their microstructural changes during mechanical testing using X-ray computed tomography KU Leuven

Martine Wevers
Structural Composites and Alloys, Integrity and Nondestructive Testing (SCALINT)
The general ambition of this project is to study in situ the microstructural changes during dynamic mechanical testing of both hierarchical composite materials and biological tissues (i.e. the bone-tendon interface) using 4D X-ray computed tomography (4DXCT). Novel experimental tools, including a generic in situ measurement device and tissue-specific contrast agents along with advanced 3D image analysis methods and computational models, will be ...

Joint deformation estimation and Computerized Tomographic reconstruction for studying dynamic processes Ghent University

Matthieu Boone
Department of Physics and astronomy

In material sciences, the analysis of a materialU+2019s structure and its deformation behavior are essential. High-resolution X-ray tomography (U+03BCCT) and particularly the imaging of dynamic processes using 4D-U+03BCCT are powerful, non-destructive tools to perform this analysis. However, full analysis requires processing of the 3D data associated with the internal motion of a material sample through time, which is called digital volume ...
