AbstractThis course covers the complete design of a full matrix capture multichannel ultrasound system for imaging or instrumentation. The selection of electronic components forming each subsystem is discussed including digital backend, transmitter, transmit/receive switches and multiplexers, impedance matching, coaxial cable, analog front end, amplifiers, and analog to digital converters is discussed. The course will also discuss integrated circuit implementation of major system blocks, describe physical integration of electronics and transducer arrays, and survey electronics for non-imaging ultrasound applications. The course includes the required fundamental background knowledge of electronics to be applicable to participants from all technical backgrounds.
Short CV of Instructor David M.J. Cowell gained his PhD from the School of Electronic and Electrical Engineering at the University of Leeds in 2008 working with the Ultrasound Group. His doctoral research area was advanced coding excitation techniques and excitation circuit design for industrial instrumentation and medical imaging systems. During this time he has performed extensive consultancy in instrumentation, FPGA and high-speed digital hardware design. After working as a research consultant in measurement and instrumentation, he joined the Ultrasound Group as a Research Fellow. His main research interests are focused on the design of high frame rate ultrasound systems for both medical and industrial applications, advanced ultrasound excitation systems with low harmonic distortion for phased array imaging and signal processing for process measurement.

Ömer Oralkan received the Ph.D. degree in Electrical Engineering from Stanford University in 2004. He is currently a Professor of Electrical and Computer Engineering at NC State University, Raleigh, NC. He has worked extensively on the design and implementation of ultrasonic microsystems using capacitive micromachined ultrasonic transducers. His current research focuses on developing devices and systems for ultrasound imaging, photoacoustic imaging, image-guided therapy, biological and chemical sensing, and ultrasound neural stimulation.
