Claim Text:
1. A magnetic resonance apparatus, comprising: a magnet unit comprising a main magnet, a gradient coil and a high frequency antenna; and a housing unit surrounding the magnet unit, wherein housing unit comprises at least one support structure unit and a cladding unit, wherein the cladding unit comprises at least one first layer and at least one second layer, wherein the at least one first layer comprises a sound absorption element, wherein the at least one second layer comprises a heavy mass layer which has a surface density of at least 3 kg/m wherein the support structure unit comprises an irregular grid-type support structure arranged on the magnet unit, wherein the grid-type support structure unit comprises a plurality of support structure elements that are different in respect of shapes to one another, wherein the cladding unit is arranged on a side of the irregular grid-type support structure unit facing away from the magnet unit, wherein the first layer of the cladding unit comprising the sound absorption element is positioned and located on the support unit facing away from the magnet unit, wherein the second layer of the cladding unit comprising the heavy mass layer is arranged on a side of the sound absorption element facing away from the irregular grid-type support structure unit and the magnet unit, and wherein a side of the second layer of the cladding unit comprising the heavy mass layer facing away from the magnet unit forms an outer casing around the magnet unit comprising the main magnet, gradient coil and high frequency antenna.
