Toward Precision Biomedical Ultrasound

【Abstract】

In recent years, there has been a remarkable advancement in biomedical ultrasound technology, particularly in the field of miniaturized transducers. These innovations have paved the way for precise and minimally invasive diagnosis and treatment of increasingly concerned diseases such as cardiovascular disease (CVD) and cancer. In this talk, micro/nanotechnology enabled small aperture ultrasound transducers were designed, fabricated and tested for precision biomedical ultrasound imaging, therapy and drug delivery. In specific, we investigated high frequency transducers for advanced intravascular ultrasound (IVUS) imaging. Small aperture forward-looking and vortex transducers were successfully demonstrated in-vitro for effective microbubbles and nanodroplets mediated intravenous sonothrombolysis. Moreover, miniaturized transducers enabled sonoporation was successful in enhancing localized drug delivery. These new findings suggest that precision biomedical ultrasound via minimal invasion can be significant in advanced ultrasound imaging, therapy, and drug delivery for unprecedented disease diagnosis and treatment.

近年来，生物医学超声技术取得了显着的进步，特别是在小型化换能器领域。这些创新为心血管疾病（CVD）和癌症等日益受到关注的疾病的精确和微创诊断和治疗铺平了道路。在本次演讲中，我将报告用于精密生物医学超声成像、治疗和药物输送，基于微/纳米技术的小孔径超声换能器的设计、制造和测试。具体来说，我们研究了用于先进血管内超声 (IVUS) 成像的高频换能器。小孔径前视和涡流换能器已在体外成功证明可用于有效的微泡和纳米液滴介导的静脉超声溶栓。此外，微小型换能器实现的声孔作用可以显著增强局部药物输送。这些新发现表明，通过微创实现的精准生物医学超声在先进超声成像、治疗和药物输送方面具有重要意义，可帮助实现前所未有的疾病诊断和治疗。
