Title: Analyzing Brain Mapping Data
Magnetic resonance imaging allows us to safely acquire data from which we can study anatomy, function and connectivity in the living human brain. But how do we convert these multimodal data into images such as that shown here. And more importantly, what information can be learned from them? In this talk I will describe how we use computational imaging to extract meaning from multimodal volumetric data. Processing involves a sequence of operations that includes feature extraction, surface parameterization, topology correction, nonrigid image registration, atlas matching and fiber tracking. I will illustrate these methods using BrainSuite (www.brainsuite.org), software which my lab has developed in collaboration with David Shattuck from UCLA. Finally I will discuss applications of these methods to epilepsy and other neurological disorders.
Richard Leahy is Dean’s Professor of Electrical Engineering, Biomedical Engineering, and Radiology at the University of Southern California and Director of the USC Signal and Image Processing Institute. 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. 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 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.
