    A tutorial presentation on "Shedding Light on Medical Ultrasound: The Combined Use of Light and Sound for Imaging and Therapy" will be given by Ronald A. Roy of Boston University on Monday, 23 May, at 7:00 p.m.


    The phenomena of light and sound propagation through tissue can be coupled in a variety of useful and interesting ways. Acoustic waves perturb mechanical properties, resulting in spatiotemporal changes in refractive index and optical scattering. If a beam of sound travels through tissue illuminated with diffuse light, photons passing through the beam are phase modulated at the ultrasound frequency, and their detection yields information on tissue absorption and scattering via a process known as the acousto-optic effect. Alternatively, if a short pulse of laser light passes through tissue possessing spatial variability in optical absorption, thermo-elastic expansion results from the rapid conversion of light energy to heat. This launches an acoustic wave, which can then be used to determine the spatial distribution of optical absorption. This phenomenon, referred to as the "opto-acoustic" or "photo-acoustic" effect, can precisely map out tissue vascularity, albeit at relatively shallow depth. "Light and Sound" have been used to effect contrast enhanced imaging using nano-particles, to image high-intensity focused ultrasound (HIFU) lesions, and even to noninvasively measure temperature. In the first half of the tutorial, we will present an introduction to the emerging field of dual wave imaging using light and sound, give a few illustrative examples, and comment on the potential for applying these concepts to clinical imaging.

    In the second half, we effect a transition from imaging mode to therapy mode simply by the addition of a high-intensity HIFU beam. Such a beam can be used to pump the acousto-optic interaction, to enhance the level of opto-acoustic emissions, and to modify the cavitation threshold of tissues and thereby promote cavitation-mediated therapy at lower (i.e., safer) acoustic intensities. The tutorial will include a brief review of physical and biological effects of HIFU-induced cavitation and will discuss how the addition of light and nano-particles enhance both the efficacy and targeting accuracy of HIFU therapy in optically diffuse tissues such as breast and brain.

    Active control of sound is an acoustic phenomenon that has been a subject of research for close to a century. With the advent of digital systems in the past few decades, great progress has been made in furthering our understanding of this technology and working towards successful applications using active noise control. Nonetheless, its capabilities and limitations have often been misunderstood. Noise control applications are numerous in our society, with passive noise control and active noise control being two general categories of noise control techniques available. Rather than these two approaches being viewed as competitive, they should more correctly be viewed as complementary, as active noise control solutions are most effective in the regime where passive noise control solutions are problematic, and vice versa. The course will cover the underlying physical principles associated with the active control of sound, as well as considerations for developing and implementing an active control system. Application areas will be identified and overviewed where active control of sound has been successfully implemented or promises to be capable of being successful in the near future.


    To introduce the physical principles, basic signal processing, and system design concepts needed to have a correct understanding of how active sound control systems operate. We will also outline application areas where active control solutions would be appropriate and where they would not be appropriate, with examples of a number of these applications.


    The short course will be taught by a team of instructors with expertise in various aspects of active control of sound. Scott Sommerfeldt is a Professor of Physics at Brigham Young University and is currently Dean of the College of Physical and Mathematical Sciences. He has been engaged in research in active control of sound and vibration for 25 years, and currently has two patents related to active control that have been issued with four additional patents pending. Dr. Sommerfeldt is a Fellow of the Acoustical Society of America (ASA) and currently is a member of the ASA Executive Council and the Institute of Noise Control Engineering Board of Directors. Kent Gee is an Assistant Professor of Physics at Brigham Young University. He has worked on research in active control of sound for 10 years as well as on research in nonlinear jet noise and rocket noise acoustics. He has one active control patent that has been issued, with an additional patent pending. Dr. Gee was the 2010 recipient of the R. Bruce Lindsay Award from the ASA.
