Row-column arrays (RCA) play a key role in advancing volumetric ultrasound imaging. However, achieving real-time beamforming across the entire imaging volume has remained a challenge—until now. In their latest work, Præsius et al. introduce a GPU-based implementation of RCA beamforming that can capture 1440 volumes per second, paving the way for true real-time volumetric imaging.
This milestone was achieved using a setup akin to traditional 2D imaging, requiring only a single graphics card, a single scanner, and 128 transmit/receive channels. Such simplicity and performance combined could revolutionize clinical volumetric imaging, enabling more detailed and dynamic patient assessments without sacrificing efficiency.
