High Frequency Ultrasonic Imaging
Saturday, 16 April, 10:15am-11:10am
High frequency ultrasonic imaging (> 30 MHz) is considered by many to be a frontier in ultrasonic imaging because higher frequencies yield much improved spatial resolution. The consequence is a reduced depth of penetration. It has many biomedical applications ranging from visualizing internal and surface structures of the blood vessel wall and mapping anterior segments of the eye, to characterizing skin tumors. An added significance is the recent intense interest in small animal imaging for the purpose of evaluating the efficacy of drugs and gene therapy. A few novel applications are being investigated at USC. These include the development of a 80 MHz 64 element linear array mounted on a biopsy needle for imaging breast tissue during biopsy with the purpose of minimizing sampling error. The main challenge lies not only in the design and fabrication of the array but also in the development of interconnect. In another project, a forward looking intravascular catheter with 32 element phased array mounted at the tip is being developed. It will facilitate catheter guidance and avoid perforation during catheterization. Current state of the art in high frequency ultrasonic imaging systems and these developments will be reviewed in this talk.
K. Kirk Shung received a Ph.D. in Electrical Engineering from University of Washington, Seattle, WA, in 1975. He had been a faculty at Penn state University, University Park, PA until 2002 when he moved to the Department of Biomedical Engineering, University of Southern California, Los Angeles, CA, as a professor. He was named a dean’s professor in biomedical engineering in 2013. He has been the director of NIH Resource Center on Medical Ultrasonic Transducer Technology since 1997.
Dr. Shung is a life fellow of IEEE, and a fellow of the Acoustical Society of America and American Institute of Ultrasound in Medicine. He is a founding fellow of American Institute of Medical and Biological Engineering. He received the IEEE Engineering in Medicine and Biology Society Early Career Award in 1985 and was the coauthor of a paper that received the best paper award for IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control (UFFC) in 2000. He was selected as the distinguished lecturer for the IEEE UFFC society for 2002. In 2010 and 2011, he received the Holmes Pioneer Award in Basic Science from American Institute of Ultrasound in Medicine and the academic career achievement award from the IEEE Engineering in Medicine and Biology Society. He is the recipient of 2016 IEEE Biomedical Engineering Award.
Dr. Shung has published more than 500 papers and book chapters. He is the author of a textbook “Principles of Medical Imaging” published by Academic Press in 1992 and two editions of a textbook “Diagnostic Ultrasound: Imaging and Blood Flow Measurements” published by CRC press in 2005 and 2015. Dr. Shung is currently serving as an associate editor of IEEE Transactions on Biomedical and Engineering, IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, and Medical Physics. Dr. Shung’s research interest is in ultrasonic transducers, high frequency ultrasonic imaging, ultrasound microbeam, and ultrasonic scattering in tissues.
