Abstract

On décrit un dispositif de pointage destiné à être utilisé en association avec un appareil d'imagerie par résonance magnétique. Le dispositif de pointage comprend : un élément ayant une forme prédéterminée, au moins un échantillon de matière réagissant à la résonance magnétique qui est placé à l'intérieur dudit élément dans une position prédéterminée, ledit échantillon étant placé de manière géométrique pour présenter une directivité distincte. Lorsque ledit dispositif est introduit dans la région d'imagerie de l'appareil d'imagerie par résonance magnétique, la position de l'échantillon peut être obtenue et indiquée sur une image de ladite cible.
