us4R, formerly USPlatform, a versatile ultrasound research platform, is based on a novel architecture optimized for direct raw RF signal streaming and processing on GPUs. The system is an all-in-one solution, composed of an ultrasound front-end, an embedded PC and a GPU cluster. PCIe communication infrastructure enables the scalability of the number of acquisition channels(64–192) and processing power(1–5 GPUs). Direct access to raw RF data(ie. channel data) and real-time software processing on the GPUs give new possibilities for research and evaluation of ultrasound algorithms and methods. The system is fully programmable(transmit, receive and processing functions). Standard software tools, CUDA/ OpenCL, can be used to develop and integrate new algorithms into the platform’s processing framework.
