Abstract

Ultrasound is the leading medical imaging modality, with more than 300 Million examinations performed annually in the United States alone. In traditional medicine, the widespread use of ultrasound in OBGYN, cardiology, urology, emergency medicine, trauma care and many other specialties has created a need for different types of machines with varying size, features, performance, portability, and other aspects.

Among such a variety, the low-end portable and handheld segment has enjoyed the most robust growth in recent years. These devices need to be small, light, and support a reasonable battery life, calling for orders of magnitude improvements in the efficiency of the rather complex and massively parallel transmit and receive circuitry.

Furthermore, in addition to conventional handheld machines, there exists a similar need for innovation in emerging ultrasound imagers based on photo-acoustic imaging, which has promise in tumor monitoring, functional brain imaging and skin melanoma detection. In this talk, I will review the requirements placed on ultrasound interface electronics and discuss our current research activities in this area. The presentation will focus on the ultrasound receive chain and highlight ideas that may lead to dramatic improvements in power efficiency and integration density, meeting the demands of future ultrasound systems.

Boris Murmann
Stanford University

Boris Murmann is an Associate Professor in the Department of Electrical Engineering at Stanford University. He received the Ph.D. degree in electrical engineering from the University of California at Berkeley in 2003. From 1994 to 1997, he was with Neutron Mikrolektronik GmbH, Hanau, Germany, where he developed low-power and smart-power ASICs in automotive CMOS technology. Dr. Murmann's research interests are in the area of mixed-signal integrated circuit design, with special emphasis on data converters and sensor interfaces. In 2008, he was a co-recipient of the Best Student Paper Award at the VLSI Circuit Symposium and the recipient of the Best Invited Paper Award at the Custom Integrated Circuits Conference (CICC). In 2009, he received the Agilent Early Career Professor Award. Dr. Murmann is a member of the International Solid-State-Circuits Conference (ISSCC) program committee, an associate editor of the IEEE Journal of Solid-State Circuits and a Distinguished Lecturer of the IEEE Solid-State Circuits Society.
