Title (EN) REDUCING MAGNETIC FIELD INSTABILITIES CAUSED BY OSCILLATIONS OF A MECHANICAL CRYOCOOLER IN MAGNETIC RESONANCE SYSTEMS
(FR) RÉDUCTION DES INSTABILITÉS D’UN CHAMP MAGNÉTIQUE PROVOQUÉES PAR LES OSCILLATIONS D'UN REFROIDISSEUR CRYOGÉNIQUE MÉCANIQUE DANS LES SYSTÈMES À RÉSONANCE MAGNÉTIQUE
Abstract:
(EN) Described here are systems and methods for mitigating or otherwise removing the effects of short-term magnetic field instabilities caused by oscillations of the cold head in a cryogen-free magnet system used for magnetic resonance systems, such as magnetic resonance imaging ("MRI") systems, nuclear magnetic resonance ("NMR") systems, or the like.
(FR) La présente invention concerne des systèmes et des procédés permettant d'atténuer ou d'éliminer les effets des instabilités à court terme d'un champ magnétique provoquées par les oscillations de la tête froide d'un système magnétique sans cryogène utilisé pour des systèmes à résonance magnétique, tels que les systèmes d'imagerie par résonance magnétique ("IRM"), les systèmes à résonance magnétique nucléaire ("RMN"), ou des systèmes de même type.
