Description
Leader of the group Computational Imaging: Tristan van Leeuwen.
Our research group is developing the next generation of 3D imaging – enabling scientists to look further into objects of all kinds. Based on mathematics, algorithms and numerical solution techniques, our approach is interdisciplinary, combining aspects of mathematics, computer science and physics. We pride ourselves on the versatility of our solutions, and our algorithms can be applied to a wide range of imaging in science, medicine and industry. In Computational Imaging, it’s our goal to constantly push the boundaries of research. By combining advanced image acquisition, parameter estimation, and discrete tomography algorithms for example, we are able to develop workflows for 3D electron microscopy at atomic resolution.

CT scan by CWI reveals hidden double-panel painting from Rubens studio
CT scans of a Rijksmuseum panel painting in CWI’s FleX-ray laboratory have revealed a surprising insight: it turns out it was not painted on oak, as was always assumed, but on tropical wood.
IMPACT4ART: the interplay between scientists, art historians, conservators and the general public
The wooden sculpture shown in the green oval is surrounded by mystery: How old is this wooden sculpture? Where and by whom was it made? Mathematics and computer science can help to answer such questions.
Insight in Wood: dating wooden objects with 3D CT imaging
Together with the Rijksmuseum, researchers of CIW's Computational Imaging group investigate art objects with the help of our state of the art FleX-ray scanner. PhD student Francien Bossema explains how they proceed.
Best Poster Prize for Allard Hendriksen
Allard Hendriksen, researcher at CWI’s Computational Imaging group was awarded the Best Poster Prize at the “Mathematics of Machine Learning” symposium.
