The Antwerp X-ray Imaging and Spectroscopy laboratory (AXIS) is one of the research groups of the Physics Department of the Faculty of Sciences in the University of Antwerp. Over the last decades the research group has built up expertise in the development of scanning X-ray equipment as well as the application in several research domains, with a main focus on cultural heritage. Numerous famous paintings of renowned artists have been scanned succesfully revealing hidden compositions and contributing to the understanding of possible pigment degradation over time.
