| 摘要 |
The invention relates to a magnetic resonance imaging (MRI) system having an open superconducting magnet system ( 1 ), which comprises a number of horizontally oriented superconducting coils ( 3 - 10 ) and a cryogenic container ( 11 ) for containing a liquid cooling medium for cooling the superconducting coils which are located within the cryogenic container. At its top, the cryogenic container is provided with a recondensor ( 23 ) for continuously liquefying the cooling medium. The magnet system has a circuit for guiding the liquid cooling medium from the recondensor along at least part of the superconducting coils.
