Abstract

In an MR tomography apparatus damping laminated sheets are provided for reducing vibrations The MR tomography apparatus has a magnet body which is surrounded by a magnet housing which surrounds and delimits an interior volume. A gradient coil system is located in this interior volume. On an inner side of the magnet housing that delimits the interior volume, a damping laminated sheet structure is provided for absorbing acoustic vibrations which are produced on switching of the gradient coil system.
