Next generation X-ray metrology for meeting industry standards (MetroFlex). University of Antwerp
Development and optimization of X-ray based analytical techniques towards the analysis of rare extraterrestrial materials. Ghent University
Micro-XRF spectroscopy, using synchrotron or conventional X-ray source based excitation, is a well-established non-destructive, microanalytical method, providing information on the elemental distributions in the probed sample. When three dimensional spatially resolved information is of interest, often a confocal micro-XRF detection scheme is applied as an alternative to XRF tomography. However, both methods pose significant challenges when ...
Electron and X-ray microscopy Community for structural and chemical Imaging Techniques for Earth materials Ghent University
Understanding earth materials is critical to creating a sustainable, carbon-neutral society due to their involvement in many vital processes. Earth materials control the feasibility of subsurface energy storage, geothermal energy extraction, and are a source of critical elements for future-proof battery technologies. However, perturbations to geological systems can also result in hazards, such as human-induced earthquakes. If we want to ...
Development of X-ray based three-dimensional micro/nano-analysis methods for the investigation of inclusions in natural diamonds and meteoritic materials Ghent University
This project aims at the further development and application of non-destructive quantitative approaches for elemental/structural micro/nano-analysis based on the use of laboratory and synchrotron X-ray imaging methodologies. This includes the optimization of three-dimensional (3D) X-ray fluorescence (XRF) and computer tomography (CT) based data acquisition strategies making use of a self-developed laboratory XRF-CT scanner. The latter ...
Development of a hybrid data-driven / model-based regularization method for X-ray CT-metrology KU Leuven
Dimensional quality control of hidden or hardly accessible features of high added-value products, produced by e.g. additive manufacturing, is becoming feasible using X-ray Computed Tomography (XCT). Mathematically, X-ray CT reconstruction is however an ill-posed inverse problem when only corrupted or incomplete data is available (i.e., there is no unique solution varying continuously with the data due to model and data uncertainties), then ...
Towards efficient and detailed analysis of turbidite records for geo- and climate hazard reconstructions – An integrated approach combining X-ray CT, magnetic, grain-size and geochemical analysis Ghent University
Turbidite records can provide valuable information on the past occurrence and magnitude of several types of geo- and climate hazards. They have been used to reconstruct earthquake recurrence and rupture patterns, flood and lahar histories, rockfall events etc. Furthermore, detailed analysis of turbidite sedimentary structures, fabric and texture has the potential to allow reconstructing sequences and timelines of the geo- and climate hazards, ...
Enabling X-ray CT based Industry 4.0 process chains by training Next Generation research experts KU Leuven
First-time-right and zero-defect manufacturing of customized lot-size-one products are essential elements of the Industry 4.0 paradigm shift to reinforce Europe’s global leadership in manufacturing. X-ray Computed Tomography (CT) metrology has a key role to play in this transition, since it is the only known technology that can certify non-destructively the quality of internal complex structures, such as those produced by additive ...
Development of regularized reconstructions for industrial computed tomography KU Leuven
Dimensional quality control of hidden or hardly accessible features of high added-value products, produced by e.g., additive manufacturing, is becoming feasible using Industrial X-ray Computed Tomography (XCT). However, reducing scanning time by e.g., acquiring corrupted (noisy or incomplete) XCT data while conserving good image reconstruction has remained a challenge up to now. This PhD project focuses on studying, developing and efficiently ...
Development of low-power Vibro-Thermal Tomography for 3D super-resolution imaging of defects in composites Ghent University
High-performance fiber reinforced polymers (or composites) are widely used in high-tech applications (e.g. in aerospace, wind energy), and require reliable and cost-effective non-destructive testing (NDT) techniques to assure their integrity. A profound NDT technique should not only detect a defect, but also extract quantitative information about its size, depth and severity. Ultrasonic and X-ray techniques are mostly used for inspection of ...
