ABSTRACT:
A magnetic resonance imaging (MRI) system having an open superconducting magnet system (1) includes a number of horizontally oriented superconducting coils (3–10) in a cryogenic container (11). The cryogenic container contains 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.
