Abstract

A magnetic resonance tomography device, wherein vibrations of device components, particularly in the low frequency range, are attenuated, as a magnet body surrounded by a magnet shell, which surrounds and defines an inner area. A gradient coil system is disposed in the inner area and an inner encapsulation cylinder also is disposed therein. The magnetic shell and the gradient coil system are externally and acoustically sealed from the inner encapsulation cylinder, and from a capsule. The capsule is formed as a three-layer system, including a cover layer, a full foam layer and a partial foam layer.
