Title (EN) RADIO FREQUENCY COIL-ARRAY FOR MAGNETIC RESONANCE EXAMINATION SYSTEM
(FR) RÉSEAU DE BOBINES RADIOFRÉQUENCE POUR SYSTÈME D'EXAMEN PAR RÉSONANCE MAGNÉTIQUE
Abstract:
(EN) A radio frequency (RF) coil array with multiple RF coil elements for a magnetic resonance examination system is disclosed. The decoupling of RF coil elements involves sets (pairs) of transformers and may also include geometrical overlap of adjacent coils. The mutual coupling between the transformers is adjustable. This provides additional degrees of freedom to fully decouple the RF coil elements from each other.
(FR) La présente invention concerne un réseau de bobines radiofréquence (RF) ayant de multiples éléments de bobine RF pour un système d'examen par résonance magnétique. Le découplage des éléments de bobine RF implique des ensembles (paires) de transformateurs et peut également inclure un chevauchement géométrique de bobines adjacentes. Le couplage réciproque entre les transformateurs est réglable. On obtient des degrés de liberté supplémentaires pour découpler complètement les éléments de bobine RF l'un de l'autre.
