M21. Imaging Modalities: Recent Advances and Beyond

The past century has witnessed accelerated development in imaging techniques for medical, biological, industrial and geophysical applications using a wide range of physical modalities. Examples include microscopy, ultrasound, X-ray transmission, positron emission, magnetic resonance, electrical impedance, photoacoustic effect, microwave radiation, atmospheric muons, and seismic waves. The realm of imaging modalities is constantly expanding. Because of their non-intrusive nature, each image reconstruction technique requires finding the solution of an ill-posed mathematical inverse problem to recover the physical properties of a medium using only external measurements. However, each modality and application considered still provides different challenges from both the theoretical and computational point of views. This mini-symposium is aiming to highlight some of the most recent, promising and exciting scientific developments to overcome them.
