Method and apparatus for maintaining thermal stability of permanent magnets in MRI systems

摘要

Briefly in accordance with one aspect, the present technique provides a method for heating a permanent magnet in a magnetic resonance imaging system. The method for heating a permanent magnet includes directly heating a surface of the permanent magnet using a surface heater. The present technique also provides a system for heating a permanent magnet in a magnetic resonance imaging system. The system includes a surface heater configured to directly heat a surface of the permanent magnet.
