摘要

Elastogram of magnetic resonance elastography (MRE) is a technique to identify the viscoelastic parameters of biological tissue by solving inverse problem from the displacement fields inside the tissue measured by the hardware of MRE. Finite element analysis (FEA) is effective to support developing elastogram. In this study, as the forward problem of elastogram three-dimensional numerical simulation of MRE measurement is conducted by applying FEA to a viscoelastic model of tissue. Then the inverse problem of elastogram is solved by applying the modified integral method to FEA results. The accuracy of numerical simulation is verified by comparing calculated results to real data measured by MRE.
