Small-Signal Equivalent Circuit Model of Long Rectangular CMUT Membranes

IEEE Open Journal of Ultrasonics, Ferroelectrics, and Frequency Control
Capacitive micromachined ultrasound transducers (CMUTs) are typically designed with many small membranes per linear array element. However, these membranes can operate out of phase or collapse at different voltages, leading to suboptimal transmit ...

Annular CMUT Arrays for Side Looking Intravascular Ultrasound Imaging

, 2007
Although side looking intravascular ultrasound (SL-IVUS) imaging systems using single element piezoelectric transducers set the resolution standard in the assessment of the extent of coronary artery disease, improvements in transducer performance are needed to perform harmonic imaging and high resolution imaging of vulnerable plaque.
