In this paper, we present a framework to estimate local ventricular myocardium contractility
using clinical MRI, a heart model and data assimilation. First, we build a generic anatomical
model of the ventricles including muscle fibre orientations and anatomical subdivisions.
Then, this model is deformed to fit a clinical MRI, using a semi-automatic fuzzy
segmentation, an affine registration method and a local deformable biomechanical model.
An electromechanical model of the heart is then presented and simulated. Finally, a data …
