METHOD OF NONINVASIVE ELECTROPHYSIOLOGICAL HEART STUDY Russian patent published in 2011 - IPC A61B5/402 A61B5/55 A61B6/03 

FIELD: medicine.

SUBSTANCE: invention refers cardiology, cardiovascular surgery, functional diagnostics and clinical cardiac electrophysiology. A method of noninvasive electrophysiological heart study involves the following stages: fixing of record electrodes on a chest surface; electrocardiogram recording; real-time processing of electrocardiogram signals; retrospective processing of the prepared electrocardiogram; computed or magnetic resonant tomography of the chest; construction and editing of computed voxel models of chest and heart organs; construction of polygonal models of torso and heart; automatic determination of position of the record electrodes on the chest surface; interpolation of the electrocardiogram signals in polygonal lattice point; reconstruction of electric field potential in the preset points; visualisation of the presented reconstructed electric field of heart; clinical estimation of results. The voxel model is constructed with using an algorithm of factorisation of shift - deformation for search transformation. The stage of construction of polygonal models includes: filtration of the reference voxel models, construction of a triangulation surface, sparsing and enhancement of the lattice with using Poisson reconstruction technique.

EFFECT: invention allows higher accuracy of noninvasive diagnostics of heart rhythm disorders and other cardiovascular diseases.
