Abstract
A variety of ultrasound elasticity imaging methods have been widely used in clinical. However, most of the existing methods are based on the assumption of organization for the pure elastic, and ignore the organization viscoelasticity effects on measurement results. In this paper, the finite element analysis method was used to calculate the different tissue deformation displacement distribution as well as the distribution of acoustic echo, etc. Using the theory of viscoelastic mechanics, we study the effects of viscoelastic parameters and sound pressure frequencies for the viscoelastic imaging of model organization. The experimental results of finite element analysis show that the viscosity of the organization cant be ignored in elastography.
