Medical Engineering Distinguished Seminar. B. (Pierre) T. Khuri-Yakub
Capacitive Micromachined Ultrasonic Transducers (CMUTs) in medical ultrasound imaging and therapy
This presentation will start with a review of the various types of ultrasound transducers and their technologies, then introduce the capacitive micromachined ultrasonic transducer (CMUT) and a brief history of its development. This will be followed by a summary of the work necessary to realize devices: theory (analytic solution, finite element modeling); modes of operation (conventional, pull-in); technology (sacrificial release, direct bonding); electronic integration (CMUT on ASIC, flip-chip on ASIC, interposer); packaging (backing, focusing lens); and system integration, and applications.
