High frequency antenna of a magnetic resonance system has diodes for connecting a tuning circuit to antenna leads in an anti-parallel or series manner according to whether the antenna signal is high frequency or direct current

摘要

High frequency magnetic resonance antenna of a magnetic resonance system has a tuning circuit arrangement (3B) with a parallel circuit arrangement of two diodes (9B, 11B) for making a high frequency electrical connection to both antenna leads (5B, 7B). The two diodes are connected to the control unit (17B) in an anti-parallel fashion for high frequencies, while they are connected in series for direct currents.
