Title (EN) TRACKING SYSTEM USING FIELD MAPPING
(FR) SYSTÈME DE POURSUITE UTILISANT LE MAPPAGE DE CHAMP
Abstract:
(EN) In some aspects, a method includes (i) causing current to flow among multiple sets of current injecting electrodes to generate a field in an organ, (ii) obtaining the positions of one or more measuring electrodes used for measuring the field generated by the current injecting electrodes, (iii) in response to the current flow, measuring the field at multiple locations in the organ using the one or more measuring electrodes, (iv) modeling the field using the measurements of the field from the one or more measuring electrodes and the positions of the one or more measuring electrodes, and (v) determining expected signal measurements of the field at additional locations within the organ using the model of the field.
(FR) L’invention concerne par certains de ses aspects un procédé qui consiste (i) à faire parcourir par un courant plusieurs ensembles d’électrodes d’injection de courant pour générer un champ dans un organe, (ii) à obtenir les positions d’une ou de plusieurs électrodes de mesure utilisées pour mesurer le champ généré par les électrodes d’injection de courant, (iii) à mesurer le champ, en réponse à l’écoulement du courant, en plusieurs emplacements dans l’organe, en utilisant la ou les électrodes de mesure, (iv) à modéliser le champ en utilisant les mesures du champ fournies par la ou les électrodes de mesure et les positions de la ou des électrodes de mesure, et (v) à déterminer des mesures de signal attendues du champ en des emplacements supplémentaires dans l’organe en utilisant le modèle du champ.
