Magnetic resonance imaging allows us to safely study anatomy, function and connectivity in the living human brain. But how do we convert these data into the increasingly ubiquitous renderings such as that shown here. And more importantly, why would we want to? In this talk I will describe how computational imaging can be used to extract meaning from volumetric data. Typical processing involves a sequence of operations that includes nonrigid image registration, surface parameterization, topology correction, atlas matching and fiber tracking. I will illustrate these methods using software available from which my lab has developed in collaboration with David Shattuck from UCLA. Finally I will discuss applications of these methods in clinical practice and brain research.


Richard Leahy is a Professor of Electrical Engineering, Biomedical Engineering, and Radiology at the University of Southern California and Director of the USC Signal and Image Processing Institute. Dr. Leahy is a Fellow of the IEEE and the recipient of the 2010 Hoffman Medical Imaging Scientist Award from the IEEE Nuclear and Plasma Sciences Society. He was general conference chair for IPMI 2001, IEEE ISBI 2004 and Fully3D 2013 and has held editorial positions with IEEE Trans Med Imaging, Phys Med Bio and Neuroimage. He has published more than 200 papers in the field of biomedical signal and image processing. His research interests lie in the application of signal and image processing to the formation and analysis of biomedical images, with applications in neuroimaging and molecular imaging using PET, MRI and EEG/MEG.
