In Memoriam: Wesley Nyborg

The biomedical ultrasound community has sadly lost one of its most important pioneers. Wesley Nyborg passed away on September 24, 2011 at the age of 94. Wes was a member of the Physics Department at the University of Vermont for over 50 years. Wes' seminal theoretical and experimental work forms the foundation for our understanding of the biological effects of ultrasound. He developed fundamental theories of the physical mechanisms of interaction of ultrasound with tissues including acoustic cavitation, ultrasound heating, and acoustic radiation force. He was a member of the National Academy of Engineering, and was recognized with the highest awards from numerous scientific societies. Wes was a Charter Member of the RCBU and was a long-time friend and colleague for many of us.
