Abstract

The aim of the work presented here is to compare two new 3D methods of cardiac kinetic analysis with the standard 2D radio nuclide angiography (ERNA). The first new method is a geometric method, based on the evolution of the ventricular 3D reconstruction, obtained after segmentation. The second method directly relies on isotopic data, without segmentation process. The results presented in this paper concern the regional representation and the global comparison of the contraction phase of the left ventricle of the heart. Results show that the 3D methods give more precise phase estimation than the reference ERNA method. This can be related to the isolation of volume of interest within 3D data
