Magnetic Resonance Imaging Guided Focused Ultrasound

Seminar: Net/Comm/DSP | April 15 | 2:30-3:30 p.m. | 521 Cory Hall

Kim Butts Pauly, Stanford University

Focused ultrasound uses a large area ultrasound transducer array outside the body to focus ultrasound to a point within the body. The amplification provided by focusing (which can be on the order of 1000-fold) provides the means to generate significant ultrasound intensities deep within the body, without significant ultrasound intensities in the intervening tissue. Magnetic resonance imaging is the only imaging modality that provides quantitative temperature mapping over a wide range of temperatures and has become essential in guiding treatments in the United States. In this talk, I will discuss our research in temperature imaging, phase aberration correction from the skull using MRI, and ultrasound-based neuromodulation.
