Abstract
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.
