<p>Shear wave characteristics are estimated (36) from analytic data. Measures of displacement are converted (34) into complex representations. The magnitude and/or phase components of the complex representation may be used for estimating (36) various characteristics, such as velocity, center frequency, attenuation, shear modulus, or shear viscosity. The zero-phase of the phase component represents an occurrence of the shear wave at that location.</p> |
