Abstract

Dans un dispositif dIRM logé dans une pièce, on retrouve un aimant mobile et dautres composants pour dautres interventions sur le patient, ainsi quun système de commande pour les mouvements relatifs de laimant et des composantes. Ce dispositif comprend une pluralité de capteurs de champ magnétique installés sur les composants pour mesurer le champ magnétique à lemplacement du composant et un mécanisme de positionnement de caméra facultatif pour que le système de commande puisse estimer les positions relatives des composants par rapport à laimant à partir de la force des champs magnétiques captés à partir de lensemble de capteurs en vue déviter des collisions pendant les mouvements.
