Abstract :
We present an algorithm for estimating active and passive mechanical properties of the heart using magnetic resonance imaging (MRI) tissue-tagging and blood pressure measurements. We combine physical modeling with a finite-element formulation and dynamic analysis, and apply non-linear optimization to estimate the unknown parameters. We assume that the myocardium´s stiffness tensor is anisotropic and non-homogeneous.
