Pre-delay reconstruction sigma-delta beamformer (SDBF) was proposed in recent years to achieve a higher level of integration in ultrasound imaging systems. The high-order reconstruction filter used in each channel of SDBF makes the beamformer highly complex. The beamformer can be simplified by recon...
