ABSTRACT:
In a communication method for a magnetic resonance signal and a reception arrangement and magnetic resonance system corresponding therewith, a non-linear reactance is supplied with a magnetic resonance signal by a magnetic resonance reception antenna and with auxiliary energy by an auxiliary reception antenna. The auxiliary energy is emitted by an auxiliary transmission antenna. The non-linear reactance mixes the auxiliary energy and the magnetic resonance signal to form a mixed signal with a sum frequency and supplies it to a mixed signal transmission antenna. The latter emits at the mixed frequency. A mixed signal reception antenna receives the mixed signal and supplies it to an evaluation device.
