Compound Lens Design and Beamforming for Wide-Field Volumetric Imaging Using a Row-Column Array.
Row-column addressed (RCA) ultrasound arrays enable volumetric imaging with a significantly reduced channel count compared to fully addressed 2-D arrays; however, their field of view (FOV) is typically limited to the transducer footprint. Diverging acoustic lenses can extend the FOV, but accurate beamforming remains ch...
