MS 13: Radon-type transforms: Basis for Emerging Imaging

Thu, 30 March, 2017, 16:30–18:30, Room: UC 202G


Bernadette Hahn and Gaël Rigaud


Inverted by Johann Radon in 1917, the Radon transform as integration along straight lines constitutes the founding principle of Computerized Tomography. Since then, engineers and researchers never stopped to innovate new imaging concepts in order to feed the constant need of information. Modalities and techniques in medical imaging as well as non-destructive testing enable to study the countless diversity of environments and objects through different characteristics and perspectives (activity of a source, anatomy of the medium, etc) and challenging various physical issues (movement, attenuation, etc). Their underlying mathematical models can often be interpreted as a generalization of the Radon transform giving rise to weighted Radon transforms as well as transforms integrating over manifolds such as spheres, circles, cones, etc. This minisymposium aims to bring together established and young researchers working on theoretical and practical aspects of such Radon-type transforms and their applications in a forum for scientific discussions.
