Patent ID: 6975900

Claim:
A method for computing epicardial surface electric potentials based on measured body surface electric potentials, the method comprising: generating a multidimensional matrix, the matrix representing at least one geometric relationship between at least one body surface electric potential measuring system and the epicardial surface, the multidimensional matrix being based on: at least one first two-dimensional (2D) image of the epicardium using a first imaging device, at least one second 2D image of the epicardium using a second imaging device, a first projection matrix associated with the first imaging device, a second projection matrix associated with the second imaging device, a computed contour of the outer surface of the heart formed from contours identified in the at least one first 2D image and the at least one second 2D image, a computed contour of the electric potential measuring system, and, a boundary element method based on the computed contour of the outer surface of the heart and the computed contour of the electric potential measuring system, using a Generalized Minimum Residual (GMRes) method to estimate an inverse of the multidimensional matrix, and, based on the inverse matrix and the measured body surface potentials, determining the epicardial surface electric potentials.
