Exploration of clinical applications of grating-based phase-contrast imaging KU Leuven
Talbot-Lau interferometry (TLI) is a recent innovation, that enables x-ray phase-contrast measurements using conventional x-ray tubes and detectors. This development allows clinical implementation of phase-contrast imaging. This had been anticipated for years, given the increased sensitivity of x-ray phase to variation in soft tissue density. Carestream Health engineered a prototype system, the CH-TLI setup, and this PhD work studied the ...
New imaging modalities in high-resolution X-ray imaging Ghent University
High-resolution X-ray imaging is a technique that is increasingly popular in many areas of research. This increase is driven by new developments, in terms of hardware and software, but also by the development of new acquisition schemes. In this project, new imaging modalities will be investigated, in particular dark field imaging and ptychography, combined with innovative hardware such as hyperspectral detectors and ICS sources.
Hyperspectral speckle-based X-ray imaging Ghent University
Speckle-based X-ray imaging is a novel method to acquire phase-contrast and dark-field datasets, two imaging modalities which yield key information about the material under investigation. We will investigate the spectral behavior of this technique in a lab environment by using a novel hyperspectral X-ray detector and exploit the additional information embedded in this spectroscopic signal.
FoodPhase: Next generation X-ray phase contrast imaging for food quality and process engineering. KU Leuven
Many properties of food, plants or seeds that are relevant to process engineering or quality are related to microstructure. Insight in food microstructure is therefore essential to control the quality of food. In the food factory of the future, flexible and efficient processes require dedicated sensor technology and automated analysis methods. In this context, X-ray computed tomography (XCT) is gaining traction as a non-destructive method to ...
A grating interferometry add-on for high-resolution X-ray phase contrast and dark-field imaging at UGCT Ghent University
To extend the potential of the infrastructure of the Centre for X-ray Tomography (UGCT), a grating interferometry add-on is requested. With this equipment multi-modal X-ray imaging will be made possible, allowing to achieve a higher contrast in low-attenuating objects and to obtain information about structures well below the conventionally feasible spatial resolution.
Nondestructive internal quality evaluation of pears using X-ray imaging and Machine Learning KU Leuven
Pear fruit are prone to developing internal disorders that leave consumers dissatisfied and unwilling to repeat their purchase. It must thus be prevented that defect fruit reach the consumer. Internal disorders, however, are invisible from the surface of the fruit. In practice, batches of fruit are, therefore, often discarded based on the result of a manual destructive inspection of a small number of randomly sampled fruit. This leads to ...
Non-destructive insect infestation detection of pear fruits by X-ray imaging and deep learning. KU Leuven
X-ray imaging enables the non-destructive visualization and quantification of the internal structure of fruits and vegetables. Implementation of inline X-ray techniques to detect internal disorders, however, requires development of fast and accurate imaging, reconstruction and detection algorithms. The aim of this PhD is to develop and test flexible 2D and 3D systems that use advanced X-ray technology such as phase contrast imaging with ...

Three dimensional breast cancer models for X-ray Imaging research. KU Leuven
Nowadays, the development of realistic three-dimensional computational and physical models of breast tumours with irregular shapes is an urgent requirement. The availability of such models is a powerful instrument in the hands of engineers, physicians and physicists to be used in the development of new technologies for precise definition of the boundaries of these cancers.
