Abstract
Shear waves are generated and measured in viscoelastic phantoms by a single push beam. Using numerical simulations or an analytical function to describe the diffraction of the shear wave, the resulting shear wave motion induced by the applied push beam is calculated with different shear elasticity values and then convolved with a separate expression that describes the effects of viscosity value for the medium. The optimization algorithm chooses the tissue parameters which provide the smallest difference between the measured shear waveform and the simulated shear waveform. A shear viscosity image is generated by applying such optimization procedure at all of the observation points.
