Identification of sources for the bidomain equation using topological gradient

Abstract : An approach for estimating electrical sources within the heart area from noninvasive measurements recorded on the outer surface of the thorax is proposed. The approach uses a topo-logical gradient method. This method consists in studying the behavior of a cost function during a disturbance within the domain. We show that our proposed approach based on the topological gradient method has actually been able to perfectly adapt to the identification of the source term for obtaining very interesting results, and a particularly low computational cost.
