Presents an algorithm for estimating active and passive mechanical properties of the left ventricle using magnetic resonance imaging (MRI) tissue-tagging and pressure measurements. The authors combine physical modeling with a finite-element formulation and dynamic analysis, and apply maximum likelihood to estimate the unknown parameters. They assume that the myocardium's stiffness tensor is anisotropic and non-homogeneous. Numerical examples demonstrate the applicability of the authors' results
