Abstract:
1. A local coil arrangement for magnetic resonance applications, comprising: a support structure; an antenna arrangement and a sensor arrangement embedded in said support structure; said antenna arrangement comprising a plurality of magnetic resonance antennas, each of said magnetic resonance antennas being configured to emit a magnetic resonance excitation signal and/or to receive a magnetic resonance signal; said sensor arrangement further comprising a plurality of magnetic field sensors and an evaluation circuit; said magnetic field sensors each detecting a magnitude of a static magnetic field in which said local coil arrangement is located and emitting a sensor output signal representing said magnitude; and said evaluation circuit receiving the respective output signals from the magnetic field sensors and determining a logic presence signal therefrom having a value dependent on whether a field strength of the static magnetic field is greater than a minimum field strength, and said evaluation circuit emitting said presence signal as an output.
