The detailed behavior of electromagnetic fields in MRI plays an important role in image quality and patient safety. Uniformly-high magnetic fields can be used to improve image quality, but commensurate high electric fields, particularly when proximate to sensitive tissues, can cause permanent damage. Faster numerical techniques can be enabling for MRI in two ways. Reasonably fast simulation can be used in MRI design optimization, by making it possible to assess a wide variety of alternative coil designs and excitation strategies. But if 3-D field analysis for a given patient could be completed in seconds, the analysis could be used to generate patient-specific excitation strategies, thus improving patient safety while enhancing image quality.
In collaboration with Laurence Wald (MGH), Elfar Adalsteinsson, and Luca Daniel, we have worked on accelering MRI simulation, and over the past few years we have made considerable progress. In this talk, we will present an overview of our joint work on accelerated volume integral equation methods, and our sparse projection approach Greens function representation, which together have led to reductions in 3-D simulation time from hours to minutes.
Bio: Professor White received his undergraduate degree in electrical engineering and computer science from MIT in 1980, and his masters degree in 1983 and his doctorate in 1985 from the University of California, Berkeley, in the same discipline. He worked at the IBM T. J. Watson Research Center from 1985 to 1987. He joined the MIT faculty in 1987 as assistant professor in EECS, becoming associate professor in 1991 and full professor in 1996. In December of 2001, Professor White was appointed as an Associate Director of the Research Laboratory of Electronics at MIT.
