Single-FPGA, Scalable, Low-Power, and High-Quality 3D Ultrasound Beamformer

We present an efficient FPGA architecture suitable for a medical 3D ultrasound beamformer. We tackle the delay calculation bottleneck, which is the heart and the most critical part of the beam-former, by proposing a computationally efficient design that is able to perform volumetric real-time beamforming on a single-chip FPGA. The design has been demonstrated for a 32×32-channel receive probe, and we extrapolated the requirements of the architecture for 80×80 channels.
