Shear wave based ultrasound elastography utilizes mechanical excitation or acoustic
radiation force to induce shear waves in deep tissue. The tissue response is monitored to
obtain elasticity information about the tissue. During the past two decades, tissue elasticity
has been extensively studied and has been used in clinical disease diagnosis. However,
biological soft tissues are viscoelastic in nature. Therefore, they should be simultaneously
characterized in terms of elasticity and viscosity. In this study, two shear wave-based …
