NUMERICAL SIMULATION OF WAVE PROPAGATION IN SOFT SOLID FOR ULTRASOUND ELASTOGRAPHY
Résumé
Transient elastography is a non-invasive method to determine the stiffness of soft tissues based on the propagation of shear wave. Finite element simulation can help postprocessing elastographic data as well as studying the impact of different parameters in this technology. However, the strong incom-pressibility of soft tissues is always a difficulty for numerical simulations. In this work, a fractional time-step method is introduced to solve this problem.
