Abstract
The dynamic deformable elastic template (DET) model has been previously introduced for the retrieval of personalized anatomical and functional models of the heart from dynamic cardiac image sequences. The dynamic DET model is a finite element deformable model, for which the minimum of the energy must satisfy a simplified equation of Dynamics. In this paper, we extend the model by integrating fiber constraints in order to improve the retrieval of cardiac deformations from cinetic magnetic resonance imaging (cineMRI). Evaluation conducted until now on cine MRI sequences shows an improvement of the recovery of the motion in images that present a low level of obvious rotation.
