High-intensity focused ultrasound (HIFU) has been used to precisely ablate a targeted area within the body without harming the overlying tissues. In recent years, HIFU, as a noninvasive, effective and feasible modality, has been used for cancer therapy. The development of HIFU transducer is the key technology of HIFU. This paper shows the acoustic lens transducer, spherical auto-focused transducer, pluralistic auto-focused transducer and the electronic phased array transducer in HIFU treatment, and the performance of each of the four HIFU transducers was evaluated.
高强度聚焦超声（HIFU）已被用于精确消融体内的目标区域，而不损伤覆盖其上的组织。近年来，HIFU作为一种无创、有效且可行的治疗方式，已被用于癌症治疗。HIFU换能器的研发是HIFU的关键技术。本文展示了HIFU治疗中的声透镜换能器、球形自聚焦换能器、多元自聚焦换能器以及电子相控阵换能器，并对这四种HIFU换能器各自的性能进行了评估。
