Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Finite element method has been developed to simulate the dynamic response of tissue which under periodic excitation pulse. Shear wave is induced by excitation and shear wave velocity is obtained by extracting the phases of shear wave at specific frequency in frequency domain analysis. The shear mechanical properties of tissue can be estimated accurately. This paper described a classic viscoelactic material model, Kelvin Voigt. The fundamental mechanical properties shear elasticity and shear viscosity, are estimated from the shear wave velocity formula in this paper. And the effectiveness of the method is illustrated by comparing the theoretic and simulated mechanical properties in Abaqus.
