Fig. 1From: Comparison of synthetic aperture architectures for miniaturised ultrasound imaging front-endsI/Q beamforming architectures. a Compressive SAB: low-rate samples are transmitted to a computational back-end for reconstruction and beamforming. b Quadrature SAB: synthetic aperture beamforming is carried out digitally in the baseband to form a 2D image, which may then be transmitted to a display deviceBack to article page
