Josh Shimony, assistant professor of radiology at the Mallinckrodt Institute of Radiology, is delivering another edition of his popular summer lecture series on the history, physics and applications of the MRI scanner. In the last twenty years, Magnetic Resonance Imaging has evolved to become the staple of imaging based research science, and its applications in neuroimaging research continue to progress and evolve.
In particular, diffusion tensor imaging (DTI) has provided a revolutionary ability to image fibrous pathways in a living subject by measuring the behavior of water in those pathways. A high-visibility example of this is the drive to image white matter pathways in the brain, a part of the brain-mapping effort of the Human Connectome Project.
This lecture explores the science and mathematical modeling behind DTI.
