Abstract
The purpose of this study is to use finite element computational simulation to investigate the accuracy of ultrasound viscoelastic creep imaging for evaluating the viscoelastic properties of a heterogeneous viscoelastic three-layer structure. The findings suggest that, in general, viscoelastic creep imaging cannot accurately evaluate the viscoelastic properties of each layer of the viscoelastic three-layer structure. Inaccuracy in the evaluation is due to deviation or distortion of the creep curve of each element within the viscoelastic three-layer structure, resulting from the interaction between complicated viscoelastic behaviors of each layer within the viscoelastic three-layer structure.
