Simulate Ultrasound Induced Radiation Force
Tissue viscoelasticity is an important biomarker for diseases like cancer and fibrosis. The goal of this project is to simulate tissue responses to ultrasound induced radiation force by Finite Element Method (FEM). Ultrasound impulses can cause local tissue to vibrate and the mechanical wave propagation can be measured. The velocity and attenuation of the waves are directly related to the viscoelasticity of the tissue, which is of great interest to the medical diagnosis. The ultimate aim of the project is to understand how waves generated by ultrasound radiation force propagate inside tissue. More importantly, it will advance current ultrasound elastography technology so that diagnosis decisions can be made with greater confidence and accuracy.
