Dispersion measurement for the oil-gelatin phantom. The phantom consists of 11% gelatin and 30% castor oil. Due to the viscosity provided by the oil, the phantom is expected to have significant dispersion as this result verifies. The results from the CrW with mechanical CW vibrators and the synthesized CrW from radiation force pushes are shown. The error bars indicate the standard deviation of the processed region of interest. The dispersion shows the slope of 0.26m/s per 100Hz.
