Dr. Lawrence A. Crum is currently Principal Physicist and Chair of the Department of Acoustics and Electromagnetics in the Applied Physics Laboratory, and Research Professor of Bioengineering and Electrical Engineering at the University of Washington. He has held previous positions at Harvard University, the U. S. Naval Academy and the University of Mississippi, where he was F. A. P. Barnard Distinguished Professor of Physics and Director of the National Center for Physical Acoustics. He has published over 180 articles in professional journals, presented over 200 papers at professional meetings, and holds an honorary doctorate from the Universite Libre de Bruxelles.

In June of 2000, he was awarded the Helmholtz-Rayleigh Interdisciplinary Silver Medal of the Acoustical Society of America.
SummaryAcoustic cavitation is a phenomenon that involves the interaction of an acoustic field with a gas bubble in a liquid. Since a bubble has a compressibility many orders of magnitude more than a liquid, the gas bubble can act as a means of concentrating the energy of the acoustic field to a restricted region of time and space. Concentrations of energy on the order of eleven orders of magnitude have been reported. This lecture will introduce cavitation as a physical phenomenon and describe some applications of cavitation to current topics in medical ultrasound.
