The experimental wire phantom images reconstructed using four different beamforming methods: (a) DAS, (b) ADMIRE, (c) DAS+CF and (d) ADMIRE+CF. The results obtained from the experimental data are correlated with simulations. The dynamic range is 100 dB to highlight side-lobes and other clutter present. The data were beamformed using sound speed of 1480 m/s.
