A generator of time-variable magnetic fields in a magnetic resonance
device with the following features:
at least one gradient coil, the conductors of which extend essentially in
the region of a hollow cylinder and which is configured free of
conductors in a central region in respect of an axial extension of the
hollow cylinder,
a high-frequency screen, which essentially encloses the conductors of the
gradient coil leaving free the central region,
parts of a high-frequency antenna, which are arranged in the central
region,
and a coaxial connecting cable associated with the high-frequency antenna,
which punctures the high-frequency screen at at least two points,
penetrating the generator essentially axially.
