摘要： A local coil for magnetic resonance applications includes a rigid housing that radially surrounds a substantially cylindrical examination volume. Arranged in the rigid housing is a transmitting coil, by which an excitation signal may be applied to the examination volume. An object to be examined arranged in the examination volume may be excited by the excitation signal for emitting a magnetic resonance signal. The local coil includes a size-variable structure, in which an antenna assembly for receiving the magnetic resonance signal emitted by the object to be examined is arranged. The size-variable structure is arranged in the examination volume and is connected to the rigid housing. The size-variable structure is soft and flexible.

摘要： A signal path for a small signal oscillating at a frequency of at least 20 GHz occurring in a magnetic resonance system has a signal source generating the small signal and a signal sink processing the small signal. The small signal is transmitted on a path from the signal source to the signal sink at least in a part section via a cable. The part section of the signal path, in which the small signal is transmitted via the cable, is embodied at least partly as a dielectric waveguide. The dielectric waveguide is disposed at least partly within an examination volume of the magnetic resonance system. The dielectric waveguide is delimited on a source side by a source-side mode converter and on a sink side, by a sink-side mode converter. The small signal is supplied to the source-side mode converter via a source-side electrical conductor and injected by the sink-side mode converter into a sink-side electrical conductor.
