Design and Fabrication of 1-D CMUT Arrays for Dual-Mode Dual-Frequency Acoustic Angiography Applications

IEEE TRANSACTIONS ON ULTRASONICS FERROELECTRICS AND FREQUENCY CONTROL, 71(1), 191–201.

author keywords: Acoustic angiography (AA); capacitive micromachined ultrasonic transducer (CMUT); dual-mode dual-frequency array; glass substrate
TL;DR: A novel scheme with a capacitive micromachined ultrasonic transducer array to receive high-frequency microbubble harmonics in collapse mode and to transmit a low-frequency high-pressure pulse by releasing the CMUT plate from collapse and pull it back to collapse again in the same transmit-receive cycle.
