A method to determine myocardial wall dynamics and tissue characteristics using a method provided to determine myocardial wall dynamics and tissue characteristics using a 3D model of the myocardium. The method comprises generating an epicardial surface and an endocardial surface from a plurality of SAX and LAX slices； identifying a plurality of nodes on the epicardial and endocardial surfaces or in between these surfaces within the myocardium in a reference frame； defining a set of coefficients, each coefficient being associated with the respective location of the corresponding node in a phase； determining the coefficients and in this way determining the model； determining the myocardial wall dynamics in terms of strain values and displacements.
