Abstract: When a portion of a structure enclosing a local coil is inserted in a homogeneity region of a basic magnetic field of a magnetic resonance system, the local coil is operable to receive magnetic resonance signals originating from a specific detection zone for the local coil arrangement. At least one conductor is arranged in the structure. Field lines of a compensation magnetic field generated by current encircling the conductor form a compensation magnetic field angle with the basic magnetic field in an edge area of the detection zone. Return conductors complete an electric circuit containing the conductor and extend in the direction of the basic magnetic field and/or are arranged such that field lines of an interfering magnetic field counteracting the compensation magnetic field encircle the respective return conductor and form an interfering magnetic field angle with the basic magnetic field in the edge area.

Abstract: A local coil arrangement for magnetic resonance applications has a base body in which at least one local coil is arranged. An excitation signal to excite an examination subject to emit a magnetic resonance signal can be emitted by the local coil and/or a magnetic resonance signal emitted by the examination subject can be received by means of said local coil. At least one volume region is present in the base body, in which an amount of a substance is located that can be excited by means of the coil or another coil so as to emit a magnetic resonance signal. A shielding is arranged in the base body. The shielding can be controlled so as to either shield or not shield the volume region depending on the control state, so that the volume region is occluded or visible with regard to magnetic resonance applications.

Abstract: 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.
