一种软件定义超声系统的硬件架构介绍

Introduction of Software Defined Ultrasound System's Hardware Architecture

该文介绍了一种软件定义超声系统的硬件架构,该架构基于超声射频数据上传,用软件方法实现了超声信号处理,并利用软件方法,实现了波束合成的真实逐点聚焦。该系统省去了硬件信号处理部分,可降低设备成本,降低开发难度,方便后期升级与维护。

This article introduces a kind of ultrasound system,named as software defined ultrasound. This system realizes the signal processing by software based on RF(Radio Frequency) data and realizes the real focus-by-point in beamforming. This architecture discards the hardware digital signal processors. It can lower the cost and reduce the design complexity. The architecture also can make system update and maintenance easier.
