近代声学教育部重点实验室,南京大学声学研究所学术报告

Ronald A. Roy, Ph. D
University of Oxford, Department of Engineering Science, Oxford, UK

Biography
Professor Roy received a B.S. in engineering physics from the University of Maine, an M.S. in physics from the University of Mississippi, and the M.Phil. and Ph.D. degrees in mechanical engineering from Yale University. He formerly served as Professor and Chairman of the Department of Mechanical Engineering at Boston University, as a Senior Physicist at the Applied Physics Laboratory and an Associate Research Professor of Bioengineering, both at the University of Washington, and on the research staff at the National Center for Physical Acoustics. Prof. Roy also served as the 65th George Eastman Distinguished Visiting Professor at the University of Oxford (2006-2007).
Trained as a physicist and an engineer, Prof. Roy specializes in the application of physical acoustics principles to problems in biomedical acoustics, industrial ultrasonics, and acoustical oceanography -- however, his true passion is the acoustics of bubbles and bubbly media. Sonoluminescence (light from sound), acoustic cavitation dynamics, shock-driven cavity collapse physics, and bubble-mediated therapeutic ultrasonics are topics of past and current interest. Most recently, he has joined colleagues in developing new techniques for imaging the optical properties of soft tissues through the nonlinear interaction of light and sound (acousto-optic imaging) and is currently exploring novel ways in which nanoparticles can be used in conjunction with laser illumination and high-intensity focused ultrasound to facilitate both optical imaging and focused ultrasound surgery. Prof. Roy has served on numerous professional society committees, review panels, editorial boards, and is a past Editorin-Chief of Acoustics Research Letters On Line. He is a Fellow of the Acoustical Society of America (ASA) and a recipient of the Helmholtz-Rayleigh Interdisciplinary Silver Medal of the ASA.

Tissue Imaging and Therapy at the Intersection of Light and Sound

Advances in our understanding of the physical acoustics of cavitation bioeffects and the interaction of light and sound is leading to the emergence of new techniques for both tissue optical imaging and high intensity focused ultrasound (HIFU) therapy. This presentation will introduce various ways that lasers and ultrasound can be combined to enhance our ability to image vasculature, deliver drugs, induce thermal and mechanical bioeffects in tissue, and noninvasively monitor the onset and progression of high intensity focused ultrasound therapy.
