摘要
主要研究了高强度聚焦声场及其检测装置。首先从理论角度分析了高强度聚焦超声(HIFU)换能器的声场特性,然后在Matlab软件中,对小振幅条件下的聚焦声场作了计算机仿真。最后理论结合实践,设计并实现了一套具有实用价值的、基于计算机采集与控制的聚焦声场三维自动检测系统,并介绍了相关软、硬件的实现过程。
This paper aimed at high intensity focused ultrasound （HIFU） and its detecting device. Firstly the acoustic field characteristics of HIFU from a theoretical perspective was analyzed,then the computer simulation of the focusing acoustic field with matlab under small amplitude situation was made,finally a set of focusing acoustic filed 3D automatic detecting system was designed and realized based on the computer data acquisition and control. The realization processes of related software and hardware was also introduced.
