Locally coils arrangement for magnetic resonance applications with the transponder for reporting of an overload

摘要

A locally coils arrangement (7) for magnetic resonance applications has a receiving coil (6) for receiving a in an examination subject (5) by means of a transmitting coil excited magnet resonance signal, and a transponder (8) on. The transponder (8) is in such a way to the receiver coil (6) are coupled, by the receiver coil (6) can be supplied with electrical power. It is designed in such a way that it sends a transponder signal on a transponder frequency, when and as soon as a by means of the transmitting coil in the receiving coil (6) reveals excitation signal exceeds a threshold value.
