Abstract
A method for assessing the contraction synchronization of a heart of a patient using a set of tridimensional images of the heart, the heart having a contraction cycle, the set of tridimensional images including tridimensional images of the heart acquired at successive phases in the contraction cycle, the heart defining a cardiac chamber, the cardiac chamber defining a chamber surface, the method comprising: segmenting the sequence of tridimensional images to extract a model of an evolution over time of the configuration of the chamber surface; computing a synchronization index for the cardiac chamber using the model of the evolution over time of the configuration of the chamber surface, the synchronization index being indicative of the contraction synchronization of the movements of the chamber surface during the contraction cycle; and assessing the contraction synchronization of the heart based on the contraction index.
