Capacitive micromachined ultrasonic transducers (CMUTs) have a nonlinear relationship between the applied voltage and the emitted signal, which is detrimental to conventional contrast enhanced ultrasound (CEUS) techniques. Instead, a three-pulse ampl

Capacitive micromachined ultrasonic transducers (CMUTs) are inherently non-linear and often believed to be unsuitable for non-linear contrast-enhanced ultrasound (CEUS) imaging. The ability of CMUTs to perform contrast-enhanced ultrasound imaging has
