Special Seminar: Sandy Cochran
July 17 @ 10:00 am - 11:00 am
Title:
“Some trends in ultrasound materials, devices and applications: a research perspective”
Abstract:
The development of ultrasound as a topic originated in the discovery and naming of the piezoelectric nature of quartz. In the subsequent 124 years, both materials and ultrasound devices have been subject to a long-term process typical of innovation, with occasional rapid advances followed by periods of consolidation.
Historical advances in materials include the development of piezoelectric ceramics, piezocomposites, and piezocrystals and advances in devices such as pulse-echo transducers, solid state 1D and 2D arrays and intravascular ultrasound. New means to use these devices must also be mentioned, with phased and linear arrays, tissue harmonic imaging, 3D and 4D imaging and therapeutic ultrasound driving advances in devices and materials. Finally, larger-scale innovation in adjacent technologies such as semiconductors, robotics, wireless networks and machine learning must also be considered.
With technology presently progressing at a very rapid pace, this talk will focus on selected advances such as flexible arrays, wearable ultrasound and new devices for intralumenal, intracorporeal and ingestible ultrasound, taking in both imaging and intervention.
Bio:
Sandy Cochran received the B.Sc. degree in electronics and the M.B.A. and Ph.D. degrees from the University of Strathclyde, Glasgow, U.K. He is currently Professor of Ultrasound Materials and Devices with the Centre for Medical and Industrial Ultrasonics, School of Engineering, University of Glasgow, UK, having held posts in engineering, physics, and medicine at other Scottish universities. His research interests include materials, devices and their supporting systems and applications for diverse applications. Topics of current interest are adoption and improvement of existing and new piezoelectric materials; microscale and miniature devices for intraluminal imaging of the gut and ultrasound-targeted drug delivery; and devices for power ultrasonics, including ultrasonic surgery, acoustic tweezing and underwater SONAR. He is a Fellow of the U.K. Institute of Physics, a Senior Member of the IEEE and a member of the U.K. Institute of Engineering and Technology, and Acoustical Society of America. He was General Co-chair of the 2019 IEEE International Ultrasonics Symposium and VP Ultrasonics and VP Symposia in the IEEE Ultrasonics, Ferroelectrics and Frequency Control Society. He has published more than 300 papers in peer reviewed journals and conference proceedings, more than 10 book chapters and patents, and delivered more than 200 other presentations.
