Comparison of shear wave speed between spherical and hybrid beam forming methods with N = 96 and zf = 30 mm in phantoms P1 and P2. In all the plots the mean and standard deviations from five measurements are shown, (a) P1 results for spherical focusing case with true speed of 1.48 m/s and ±0.15 m/s threshold, (b) P1 results for hybrid focusing case with true speed of 1.48 m/s and ±0.15 m/s threshold, (c) P2 results for spherical focusing case with true speed of 3.96 m/s and ±0.15 m/s threshold, (d) P2 results for hybrid focusing case with true speed of 3.96 m/s and ±0.15 m/s threshold.
