In the cardiac electrophysiology imaging community the most widely used approach to solve the inverse problem is the least square formulation with different Thikhonov reg- ularizations. Clinicians are not yet fully satisfied by the technology that solves the inverse problem. Reformulating the inverse problem could bring new techniques to solve it. In this paper we use the Steklov-Poincar ́ e formulation of the Cauchy problem in order to solve the inverse problem in electrocardiography imaging. We present in this work the technique and an algorithm of gradient descent. We also show numerical results based on simulated syntheti- cal data< Leer menos
