Abstract

A microacoustic system based on a wide-bandwidth commercial piezoelectric transducer is presented in this letter. The system allows objective measurement of nonlinear Rayleigh scatter from single microbubbles. Two different types of microbubbles were exposed to a range of ultrasonic frequencies and amplitudes. Statistical examination of their scatter provides an understanding of their dissolution/destruction behavior and an insight on inertial cavitation. These high sensitivity measurements are key to the understanding of nonlinear scatter, may be employed to devise new signal processing techniques for imaging and better microbubble engineering.
