Recent works on focused ultrasound (FUS) have shown great promise for cancer therapy. Researchers are continuously trying to improve system performance, which is resulting in an increased complexity that is more apparent when using multi-element phased array systems. This has led to significant efforts to reduce system size and cost by relying on system integration. Although ideas from other fields such as microwave antenna phased arrays can be adopted in FUS, the application requirements differ significantly since the frequency range used in FUS is much lower. In this paper, we review recent efforts to design efficient power monitoring, phase shifting and output driving techniques used specifically for high intensity focused ultrasound (HIFU).
近期关于聚焦超声（FUS）的研究工作在癌症治疗方面展现出了巨大的潜力。研究人员一直在努力提高系统性能，这导致了多阵元相控阵系统的复杂性增加。这促使人们通过系统集成来显著降低系统的尺寸和成本。虽然来自微波天线相控阵等其他领域的概念可以应用于 FUS，但由于 FUS 使用的频率范围低得多，因此应用要求有很大的不同。在本文中，我们回顾了近期在设计高效功率监测、相移和输出驱动技术方面的努力，这些技术专门用于高强度聚焦超声（HIFU）。
