Un modèle numérique anthropomorphique de coeur battant

We present a realistic anthropomorphic numerical model of the beating heart. It includes the main cardiac anatomical structures, vessels junctions and part of the coronary network. Its main feature is that it is based on an imaging study of the same human subject from which both structural and motion information are retrieved. This confers to the model a remarkable consistency. Heart's deformation is assessed through successive non linear registrations in cine MR sequences. The resulting model can be used as a reference for the evaluation of cardiac image processing algorithms such as heart segmentation and cardiac image registration.
