Decomposition of Test Magnetic and Electropotential Images with Non-Dipole Structure According to Multipole Expansion

摘要

An approach to analysis of magnetic and electropotential maps, consisting in their expansion into orthogonal images using the two-dimensional Fourier transform, is suggested. The method has a unique solution, is performed correctly, possesses a possibility of space map filtration, error does not exceed 3 %. This approach can be useful in development of new methods of noninvasive diagnosis of electrophysiological abnormalities in human heart, characterized by the presence of complex (non-dipole) source of bioelectric activity.
