A sigma-delta-based sparse synthetic aperture beamformer for real-time 3-D ultrasound
Sigma-delta modulation allows delay resolution in ultrasound beamformers to be achieved by simple clock cycle delays applied to the undecimated bit-stream, greatly reducing the complexity of the signal processing and the number of bits in the datapath. The simplifications offered by this technique h...
