摘要： 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.

摘要： An RF antenna arrangement of a combined MR/PET system is disclosed. In at least one embodiment, the RF antenna arrangement includes a first part installed in the examination tunnel in a fashion fixed to the system such that it is arranged underneath the couch board when the latter is introduced, and a second part, which can be placed onto the couch board and be introduced into and withdrawn from the examination tunnel together with the couch board. In at least one embodiment, the second part is of dimensionally stable design and has a clear cross section that is adapted to the object to be examined. Consequently, the time outlay for applying the RF antenna is reduced, and the fixed position of the RF antenna enables a correction of the attenuation of gamma rays. Furthermore, a number of second parts having various diameters can be provided.
