PROCÉDÉ DE RÉGLAGE DE FRÉQUENCE DE RÉSONANCE D'UNE BOBINE RF POUR UN SYSTÈME DE RÉSONANCE MAGNÉTIQUE, DISPOSITIF CRYOGÉNIQUE ET ENSEMBLE DE SYSTÈME DE RÉSONANCE MAGNÉTIQUE COMPRENANT UN TEL DISPOSITIF CRYOGÉNIQUE

摘要

The invention relates to a method of tuning the resonance frequency of a RF coil for a Magnetic Resonance Measurement System. The method comprising the steps of : - providing a RF coil holder (19), a cold source and a heat source thermally linked to the RF coil holder (19); arranging the RF coil (130) on the RF coil holder (19); applying cold to the RF coil holder (19) in order to reduce the RF coil (130) temperature below a critical temperature of the superconductor; while cold is still applied and the Magnetic Resonance Measurement System being configured, tuning the resonance frequency of a RF coil (130) by increasing the temperature of the RF coil (130) using the heat source.
