DescriptionThis study seeks to simulate soft tissue behavior with a custom finite element analysis. It is the eventual goal of this team to explore the inverse problem of soft tissues, and this simulation study will play an integral role in that process. It is hoped that new information regarding the elastic properties of soft tissue can be used to diagnose disease processes and improve health care delivery.
In this investigation, soft tissue is modeled as a linear, isotropic, elastic, and nearly incompressible material. A dynamic finite element problem was defined consistent with the experimental protocol of harmonic motion imaging, an elasticity imaging technique that utilizes acoustic radiation force to induce localized displacements within soft tissue samples.
The finite element equations of motion in this investigation were solved using the Newmark method, an approach commonly used by engineers to determine the dynamic response of structures under the action of any general time-dependent loads. It was found that the displacement results obtained with the Newmark method made physical sense and agreed with the observations of other researchers in this field, suggesting that the current finite element analysis is a suitable simulation of soft tissue behavior.
