摘要
医学上利用高强度聚焦超声(HIFU)的物理效应实现非介入无创治疗。相控阵HIFU是通过控制多个发射信号的初始相位使得超声波在焦点处同相叠加而实现聚焦。本文介绍了相控阵HIFU中电子控制系统的一些关键技术设计,包括初始相位设置、相位跟踪保持、系统体系结构以及信号传输和数据通信方案等。
The physical effects of high intensity focused ultrasound （HIFU） are used for non -ablative treatment. The phased array HIFU system makes the phase of the acoustic emission signals same at the focus through controlling the initial phase. This paper introduces the key technology of the electronic control system of the phased array HIFU, including setting the initial phase, tracking the phase, keeping the phase, the system structure, signal transmission and data communication.
