Automated, Accurate and Fast Segmentation of 4D Cardiac MR Images
Based on discrete mathematical morphology, we propose a new automated and fast procedure to segment the left ventricular myocardium in 4D (3D+t) cine-MRI sequences. Thanks to the c...

Constitutive Modeling of Cardiac Tissue Growth
Abstract. Long term responses of the heart to e.g. infarction or surgical intervention are related to response of the tissue to changes in the mechanical environment. The tissue re...
