Title:          Some Mathematical Problems in Medical Imaging

Abstract: 

In this talk I will describe some computational problems that arise in Magnetic Resonance (MR) Imaging. I will focus on two problems: MR Angiography, which is the use of MR to examine blood vessels; and parallel imaging, which is probably the most important advance in MR in the last decade. In both of these problems, we have obtained some exciting initial results. For a certain class of MR Angiography problems we now have algorithms that are better at generating high-quality images than experienced radiologists. For parallel imaging, we have recent developed a maximum likelihood method that overcomes a serious limitation of the standard algorithm. I will also give an overview of some open problems in this area.
