specification

us4R-lite is a low-cost portable ultrasound research system with direct software access to raw RF signals (ie. channel data). The system consists of an ultrasound front-end module with a Thunderbolt interface and an optional embedded Nvidia Tegra X2 GPU module. Fully programmable transmit, receive and processing functions predispose the system to research and educational applications.
A novel system architecture is optimized for Software-Defined Ultrasound paradigm and GPU-based processing. Ready-to-use software examples and GPU kernels make it easy for a first-time user to start working with the device. The user’s own algorithms can be easily developed using standard CUDA/OpenCL frameworks enabling real-time implementation of custom image processing methods.
