肿瘤治疗用高强度聚焦超声换能器的研究现状

摘要

高强度聚集超声(High-intensity Focused Ultrasound,HIFU)作为一种非侵入性、无毒副作用、具有巨大潜力的肿瘤治疗手段,近年来已经越来越受到国内外学者的广泛关注.高强度聚焦超声换能器是HIFU肿瘤治疗设备的核心部件,直接影响治疗的效果.因此,本文就其发展过程、治疗机制及应用等相关问题做一综述.%As non-invasive technique with non-toxic side effects and great potential, high-intensity focused ultrasound(HIFU) has received widespread attention from scholars both at home and abroad in recent years. Higb- intensity focused ultrasound transducer is the core component of HIFU treatment equipment for oncotherapy, which chould affect the therapeutical result directly. Therefore, this paper summarizes some related issues of high-intensity focused ultrasound transducer, including its development, working principle, applications and so on.
