Evaluation of CMUT annular arrays for side-looking IVUS

2009 IEEE International Ultrasonics Symposium, 2009
Side-looking (SL) IVUS probes are extensively used for management of cardiovascular diseases. Currently SL-IVUS imaging probes use either a single rotating transducer element or solid-state arrays. Probes with single rotating piezoelectric transducer have simple front-end, but have fixed focused operation, and suffers from motion artifacts. Solid-state

A nonlinear lumped model for ultrasound systems using CMUT arrays [PDF]

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2015
We present a nonlinear lumped model that predicts the electrical input-output behavior of an ultrasonic system using CMUTs with arbitrary array/membrane/electrode geometry in different transmit-receive configurations and drive signals. The receive-only operation, where the electrical output signal of the CMUT array in response to incident pressure ...
