Abstract

Cette invention se rapporte à des systèmes et à des procédés étalonnés servant à localiser une structure errante à l'intérieur d'une partie du corps. A cet effet, on établit un champ électrique à l'intérieur de cette partie du corps entre une électrode d'émission d'énergie électrique et une référence électrique. Un signal de sortie de navigation est dérivé de cette structure errante sur la base d'une fonction qui exprime une relation entre une caractéristique électrique détectée au niveau de la structure errante et une distance séparant la structure errante et l'électrode d'émission d'énergie électrique. Une première et une seconde électrode, espacées par une distance connue, sont présentes dans le champ électrique. On ajuste la fonction en question en comparant cette distance connue avec au moins un signal de sortie de navigation dérivé, qui est dérivé sur la base de cette fonction par détection d'une caractéristique électrique au niveau de la première et de la seconde électrode.
