摘要：
A three-dimensional model of the patients body surface of 360 degrees with the coordinates of ECG electrodes is formed via a computer program according to data of three-dimensional photo-scanning of the patients body surface from above and data of three-dimensional photo-scanning of the patients back imprint. Position of ECG electrodes on the body surface relative to the surface of the heart is determined via computer simulation and combining a three-dimensional model of the body surface of 360 degrees, obtained during three-dimensional photo-scanning, and a three-dimensional model of the heart and the inner surface of the chest, obtained during CT or MRI procedure. Combining a three-dimensional model of the body surface of 360 degrees, obtained during three-dimensional photo-scanning, and a three-dimensional model of the heart and the inner surface of the chest, obtained during CT or MRI procedure, is performed on the basis of the specific anatomic characteristics of the patient's body surface and the inner surface of the chest, which are deemed to be unchanged for a specified time period, or on the basis of combining three markers, visible during three-dimensional photo-scanning and during CT or MRI procedure, or on the basis of a single system of coordinates for three-dimensional photo-scanning and CT or MRI procedure. The invention implementation results in improvement of the technique of visualization of the patients body surface.La présente invention concerne la médecine, en particulier la cardiologie et les diagnostics fonctionnels, et peut être utilisée lors d'une procédure de diagnostic par cartographie électrophysiologique non invasive du cœur. Un modèle tridimensionnel de la surface du corps de patients à 360 degrés comportant les coordonnées d'électrodes d'ECG est élaboré grâce à un programme informatique sur la base de données de numérisation tridimensionnelle de la surface du corps de patients par le dessus (fig. 2 et fig. 3) et de données de numérisat
