Abstract

Traditional ultrasound imaging systems have a high sampling rate of 40–80 Msps and a data volume of few hundred million bits per frame. This work proposes a frequency domain beamspace receive beamformer to reduce this high sampling rate and data volume. In the proposed beamformer, analog RF signals are sampled in frequency domain and modified beamspace minimum variance beamformer is applied on the reconstructed signal. The proposed beamformer is simulated using phantoms of point scatters, disc–cyst and human kidney and compared with the time domain beamforming techniques by quantifying lateral resolution of the beams, contrast resolution and structural similarity of images. The measured metrics show a comparable image quality with reduction in the sampling rate by tenfold to 40-fold and the data volume by two- to fivefold.
