Correlative full field X-ray compton scattering imaging and X-ray computed tomography for in situ observation of Li ion batteries Ghent University
Combination of shape and X-ray inspection for apple internal quality control: in silico analysis of the methodology based on X-ray computed tomography KU Leuven University of Antwerp
© 2018 Elsevier B.V. Multisensor inspection allows for inline detection of internal defects of products with variable shapes, such as fruit and vegetables, by combining X-ray radiography with 3D shape recognition and modelling. For products with a complex internal structure such as apple fruit, inspection must also account for the corresponding internal density gradients that can affect X-ray radiographic images. Apple fruit consist of different ...
Quantitative reconstruction of polychromatic X-ray fluorescence computed tomography using transmission tomography Ghent University
Understanding the mechanical strength and dynamic structural changes of wood-based products using X-ray computed tomography Ghent University
The mechanical strength of wood-based products (WBP) is determined by the anatomical structure of wood, including the specificities of earlywood (EW) and latewood (LW), and the bonding interphase between wood and adhesive. In this study, two-layered specimens were manufactured according to three possible assembling strategies in terms of the anatomical structure of wood. Wood micro-structure and phenol formaldehyde (PF) adhesive distribution ...
Comparison of several phase retrieval and phase correction methods for single-image in-line X-ray phase contrast tomography Ghent University
Iterative reconstruction algorithms for the reduction of artifacts in high resolution X-ray computed tomography Ghent University
A multiresolution approach to iterative reconstruction algorithms in X-ray computed tomography Ghent University
In computed tomography, the application of iterative reconstruction methods in practical situations is impeded by their high computational demands. Especially in high resolution X-ray computed tomography, where reconstruction volumes contain a high number of volume elements (several giga voxels), this computational burden prevents their actual breakthrough. Besides the large amount of calculations, iterative algorithms require the entire volume ...
New imaging modalities in high resolution X-ray tomography Ghent University
For more than 100 years, X-rays are used in medical diagnostics, materials science and many other research domains for the possibility they offer to look through objects. Since the 1970s, Computed Tomography or CT allows for acquiring a full 3D representation of an object or a patient. In the 1980s, technological advances led to the development of high resolution X-ray CT or µCT. Using this technique, objects can be investigated with a spatial ...
High spectral and spatial resolution X-ray transmission radiography and tomography Ghent University
In high-resolution radiography and tomography, the local intensity of the X-ray beam is typically measured using an energy-integrating detector system, thus discarding all information on the detected X-ray spectrum. Recently, several direct or hybrid detector systems have been developed which allow for single photon counting using one or more energy thresholds [1]. By measuring the same object at different energy thresholds, it becomes possible ...
