![]() ![]() These arrays have been operated in immersion with no failure or degradation in performance over the time. We fabricated 64- and 128-element 1-D CMUT arrays with 100% yield and uniform element response across the arrays. We present the first pulse-echo phased array B-scan sector images using a 128-element, one-dimensional (1-D) linear CMUT array. The aim of this paper is to demonstrate the viability of CMUTs for ultrasound imaging. ![]() Recently, capacitive micromachined ultrasonic transducers (CMUTs) have emerged as an alternative technology offering advantages such as wide bandwidth, ease of fabricating large arrays, and potential for integration with electronics. Abstract: Piezoelectric materials have dominated the ultrasonic transducer technology.
