Patent ID: 7834626

Claim:
A magnetic resonance system configured to generate a magnetic resonance exposure of an examination subject comprising: a magnetic resonance data acquisition unit having an opening therein configured to receive an examination subject in an examination region of the data acquisition system; said data acquisition unit comprising a gradient coil system and a gradient coil cooling system that cools said gradient coil system; a patient bed, configured to receive a subject thereon, that is movable relative to said opening of said data acquisition unit in order to position a portion of the patient in said examination region; an antenna structure, comprising a plurality of antenna elements, permanently installed in said data acquisition unit in said examination region, and separate radio-frequency circuits respectively associated with said antenna elements individually or in groups; at least one of said radio-frequency circuits being in thermal communication with said gradient coil cooling system and is cooled by said gradient coil cooling system; a plurality of feed lines respectively connected to said antenna elements to feed signals into the respective antenna elements in order to cause the antenna elements to radiate a radio-frequency field in the examination region and/or in order to receive radio-frequency signals acquired by the respective antenna elements from the examination region; radio-frequency shielding located in spatial relation to said opening of said data acquisition unit in order to shield an external region outside of said opening from the radiated radio-frequency field; said radio-frequency shielding comprising a plurality of feedthroughs therein, through which said feed lines respectively proceed along a distance from said external region to the respective antenna elements; and each of said feed lines having at least a portion thereof formed as a coaxial cable having an outer conductor, with the respective outer conductors of the feed lines being in electrical connection with the radio-frequency shielding.
