摘要：
Magnetic resonance elastography (MRE) is emerging to virtually palpate human body and visualize tissue elasticity. Although MRE receives more and more attention in clinic, the study is limited due to the inaccessibility and expensiveness of magnetic resonance scanning. A numerical model is thus proposed by analyzing tissue elasticity and the forced movement differential equation. The finite element method (FEM) is introduced to resolve this numerical model of MRE. Its performance is validated with different models of tissue structure and elasticity composition. The results of quantitative experiments confirm that the new model is effective to promote numerical MRE study. © 2017, Chinese Institute of Electronics. All right reserved.
