内容简介:

Advanced ultrasound imaging and therapy present unprecedented challenges to transducer technology. In this talk, recent study on novel ultrasound transducers, arrays and the associated applications is presented. In specific, we investigated micromachined piezoelectric composite transducers with broad bandwidth for high frequency intravascular ultrasound (IVUS) imaging and non-destructive testing. Dual frequency transducers were also successfully demonstrated for contrast enhanced superharmonic intravascular and intracavitary imaging. In ultrasonic therapy study, we recently demonstrated ultrasound-induced site-specific cell membrane permeabilization (sonoporation) at the cellular level. We also demonstrated multi-frequency ultrasound induced efficient tissue ablation. As a new member in ultrasound transducer family, laser ultrasound has recently shown broad bandwidth and its promising applications in drug delivery and intravascular thrombolysis. These new findings suggest that broadband transducers are increasingly important in advancing ultrasound in medicine, biology and industrial applications.
