Algorithm development for direct image reconstruction is Dr. Patch's area of training, although she currently collects experimental data. Her current research focus is thermoacoustic imaging technique, a hybrid technique in which rapid heating induces outgoing pressure pulses, which are detected noninvasively by transducers surrounding the field of view. Dr. Patch has developed an inversion formula for idealized thermoacoustic data and now works to account for physical and experimental effects. Thermoacoustic testbed development software HFSS code and a companion set of instructions are outcomes of NIH award R21CA137364. Recommended methods for downloading the code are available in Dr. Patch's website. Video demonstrations of the gantry operation are available in the QuickTime or VLC and for Windows.
Sarah Patch received her BS in Mathematics & Computational Sciences from Stanford University in 1989 and her PhD in Applied Math from UC Berkeley in 1994. She then obtained a National Science Foundation Postdoctoral Fellowship in Mathematical Sciences and worked at the Institute for Mathematics and its Applications from 1994 to 1995. In 1995, she was awarded a Humboldt Postdoctoral Fellowship to work at the University of Muenster, Germany. The following year Patch went back to Stanford University. From 1997 to 1999 Patch held a position GE’s Corporate Research and Development Center; in 2005 she joined GE Medical Systems’ Applied Science Lab in Milwaukee.
Since 2005, Sarah Patch has been working at University of Wisconsin-Milwaukee, where she holds the rank of Associate Professor. Professor Patch has received more than 10 patents and her current research is supported by a UW-Milwaukee Research Growth Initiative Award.
