报告简介

Emerging ultrasound biomedical imaging and therapy present unprecedented challenges to transducer technology. In this talk, recent study on broadband ultrasound transducers 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 dual frequency transducers for contrast enhanced 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 and biology.

如今新兴的超声生物医学成像和治疗传感器技术面临着前所未有的挑战。在本次报告将展示宽带超声换能器和相关应用的最新研究。具体而言我们研究了微机械压电复合换能器的高频血管内超声(IVUS)成像和双频换能器的腔内宽频带增强造影。此次报告将展示我们近期所研究的超声诱导特异性细胞膜通透性的超声治疗成果还会演示多频超声诱导的高效组织消融。光-声换能器作为超声换能器家族中的一员近年来在药物输送和血管内溶栓等方面显示出了广阔的应用前景。这些新的研究结果表明宽带换能器越来越重要并将推进超声在医学和生物学的应用。
