摘　　要：生物医学超声传播实验是生物医学超声教学的重要内容,对帮助学生深入掌握超声物理基础以及相关实验设备的原理与使用具有重要价值。传统实验开设受时间、环境和设备成本的制约,为此,基于Matlab App Designer环境开发系统,通过可视化交互式界面设计和模块化虚拟仪器仿真,实现一套完整的信号发生、参数设置、数据处理、数据存储和显示的实验系统。系统可完成超声透射、反射、衰减和非线性参数B/A测量等实验,能够直观、灵活地展示超声传播的规律,并可进行信号二次处理与分析,能帮助学生更好地理解超声传播特性,培养学生的工程素养和研究能力。The medical ultrasound propagation experiment is an important basis of biomedical ultrasound,which is of great value for mastering the theory and application of medical ultrasound equipment.The traditional medical ultrasound propagation experiments are restricted by time,environment and cost of equipment.Therefore,a virtual simulation system is developed based on Matlab App Designer environment.Through visual interactive interface design and virtual experimental instruments simulated,a complete experimental system comprised of signal generation,parameter setting,and data acquisition,processing and display is built.Four sub-experiments including ultrasonic transmission,ultrasonic reflection,ultrasonic attenuation and nonlinear parameter B/A measurement experiments are realized by this system.It can show the law of ultrasonic propagation to students intuitively and flexibly,which can help students to understand features of ultrasonic propagation,and cultivate their engineering literacy and research ability.
