Reducing Magnetic Field Instabilities Caused by Oscillations of a Mechanical Cryo-Cooler in Magnetic Resonance Systems

摘要

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.
