Abstract

L'invention concerne un système permettant de produire une image IRM d'une partie d'objet à partir de signaux de résonance magnétique produits par ladite partie d'objet en réponse à un signal R.F. transmis à cette partie d'objet lorsqu'il se trouve dans un champ magnétique statique et homogène. Ledit système comprend: i) une sonde permettant de détecter des signaux de résonance magnétique lorsqu'ils sont à proximité de la partie d'objet; et ii) un ensemble de traitement de signaux conçu pour recevoir un signal de sortie provenant de la sonde et le traiter en ensembles de données d'image. La sonde comprend une pluralité de détecteurs R.F., chacun d'eux possédant un emplacement et une adresse définis.
