使用Field-II进行超声波束形成的设计仿真

摘要

超声发射和接收波束是决定超声诊断系统性能的关键因素,设计上往往受到复杂的声场相互关系困扰.Field-II是一种能够仿真各种超声换能器并生成图像的一种工具,它能够提高设计仿真工作的效率和正确性,本文介绍使用Field-II进行超声发射和接收波束形成的设计仿真方法.%Ultrasonic transmiting and receiving beamforming is a key factor to determine the performance of ultrasonic diagnostic systems. The design is often affected by the complicated ultrasound field. Field-II is a tool for simulation of a variety of ultrasonic transducers and images, which can improve the efifciency and accuracy of design and simulation. This article describes the use of Field-II for simulation design of ultrasonic transmiting and receiving beamforming.
