Abstract

L'invention concerne des systèmes et des procédés d'exécution d'imagerie par résonance magnétique (IRM) sur des animaux éveillés. Afin de positionner un animal éveillé par rapport au système radiofréquence de bobine double fonctionnant dans un système d'imagerie par résonance magnétique de haute résolution afin de produire des images de haute résolution sans artéfacts dus aux mouvements, on utilise des appareils de contention de la tête et du corps de l'animal.
