Abstract

A magnetic resonance tomography apparatus has a basic field magnet that is surrounded by a magnet envelope. This basic field magnet surrounds and limits an interior space with a gradient coil system disposed in this interior space and a body coil having an RF antenna and a carrying tube disposed in said gradient coil system as an inner encapsulation cylinder. The magnet envelope and the gradient coil system are both optically as well as acoustically closed by the body coil and a cladding at the end faces and in the interior. The body coil is manufactured by a vacuum casting or vacuum die-casting process.
