The experimental test of novel ultrasound (US) investigation methods can be made difficult by the lack of flexibility of commercial US machines. In the best options, these only provide beamformed radiofrequency or demodulated echo-signals for acquisition by an external PC. More flexibility is achieved in high-level research platforms, but these are typically characterized by high cost and large size. This paper presents a powerful but portable US system, specifically developed for research purposes. The system design has been based on high-level commercial integrated circuits to obtain the maximum flexibility and wide data access with minimum of electronics. Preliminary applications involving nonstandard imaging transmit/receive strategies and simultaneous B-mode and multigate spectral Doppler mode are discussed.
新型超声（US）探测方法的实验测试可能会因商业 US 机缺乏灵活性而变得困难。在最佳选择中，这些仅为外部 PC 采集提供波束形成射频或解调回波信号。在高级研究平台中可以实现更高的灵活性，但这些平台通常具有成本高和体积大的特点。本文介绍了一种专为研究目的而开发的强大但便携的 US 系统。该系统设计基于高级商业集成电路，以在最小的电子设备下获得最大的灵活性和广泛的数据访问。本文还讨论了涉及非标准成像发射/接收策略以及同时 B 模式和多门频谱多普勒模式的初步应用。
