Patent ID: 6856830

Claim:
A method of imaging of electrical activities in a heart within a body comprising the steps of: (a) collecting signals over a part of a surface of the body, a part of the surface of the heart within the body, or a part of a surface out of the body, using a plurality of sensors and a data acquisition unit, (b) determining positions of the sensors, (c) determining geometry information of the heart within the body and of the torso, (d) constructing an electrical source model of the heart, which comprises a three dimension distribution of current dipoles or monopoles or electric potentials, or a computer heart model incorporating physiological a priori information that simulates the physiological and pathophysiological processes of the heart; (e) estimating activation patterns of the electrical activity within the three dimension space of the heart, by comparing and minimizing the difference between the collected signals and source model generated signals over the same sensor positions and over a certain time epoch, and (f) displaying the estimated activation patterns within the three dimension space of the heart.
