Device for producing images and spatially resolved spectra of a test object by means of nuclear magnetic resonance

摘要

The invention relates to an NMR tomography device having a cryostat for holding the basic field coils. Provided on the top side of the cryostat is a tower (2) for the supply with liquid gases and for introducing electric lines and in the interior of which guide tubes (13, 14) are arranged in an outer tube (12). The guide tubes (13, 14) are surrounded by a helix (15) made from a material which is a good conductor of heat. A corresponding helix can also be arranged in the interior of each guide tube itself.
