Changes in biomechanical properties of biological soft tissues are often associated with
physiological dysfunctions. Since biological soft tissues are hydrated, viscoelasticity is likely …

In this study, we describe numerical implementation of a heterogenous, nearly
incompressible, transverse isotropic (NITI) finite element (FE) model with key advantages for …

A new viscoelastic wave inversion method for MRE, called Heterogeneous Multifrequency
Direct Inversion (HMDI), was developed which accommodates heterogeneous elasticity …

Purpose To test the hypothesis that removing the assumption of material homogeneity will
improve the spatial accuracy of stiffness estimates made by Magnetic Resonance …

Magnetic resonance elastography (MRE) is a powerful technique for noninvasive
determination of the biomechanical properties of tissue, with important applications in …

Tissue-mimicking phantoms with well-defined properties can help in identifying the potential
weaknesses in medical imaging systems. Among the imaging systems, magnetic resonance …

We derive and analyse a new way to calculate the shear modulus of an inhomogeneous
elastic material from time-dependent magnetic resonance elastography (MRE) …

L'imagerie biomédicale d'élastographie, visant à cartographier les propriétés mécaniques
des tissus mous, est explorée à travers des approches multiphysiques et multimodales …

Inverse problems arise in an enormous variety of science and engineering applications
where model parameters must be estimated from noisy and indirect observational data …
