Title (EN) INTRABODY PROBE NAVIGATION BY ELECTRICAL SELF-SENSING
(FR) NAVIGATION DE SONDE INTRACORPORELLE PAR AUTO-DÉTECTION ÉLECTRIQUE
Abstract:
(EN) Methods and systems for position determination are described for using an intrabody probe having a plurality of electrodes to generate a plurality of different electrical fields, and to also measure, using the plurality of electrodes, a measurement set (a Ve-e measurement set) comprising a plurality of measurements of the plurality of different electrical fields while the probe remains in one position. From the Ve-e measurement set, spatial position coordinates for the intrabody probe are estimated within an intrabody coordinate system, using an established mapping between previously observed Ve-e measurement sets and positions in the intrabody coordinate system. Systems and methods for generating and selecting such mappings are also described.
(FR) L'invention concerne des procédés et des systèmes de détermination de position pour utiliser une sonde intracorporelle ayant une pluralité d'électrodes en vue de générer une pluralité de champs électriques différents, et en vue également de mesurer, à l'aide de la pluralité d'électrodes, un ensemble de mesures (un ensemble de mesure Ve-e) comprenant une pluralité de mesures de la pluralité de champs électriques différents tandis que la sonde reste dans une position. À partir de l'ensemble de mesures Ve-e, des coordonnées de position spatiale de la sonde intracorporelle sont estimées à l'intérieur d'un système de coordonnées intracorporelles, à l'aide d'une mise en correspondance établie entre des ensembles de mesure Ve-e précédemment observés et des positions dans le système de coordonnées intracorporelles. L'invention concerne également des systèmes et des procédés permettant de générer et de sélectionner de telles mises en correspondance.
