Zusammenfassung:	In a method for correcting the interference in respiratory navigation, transmitting, during magnetic resonance scanning, a respiratory signal generated by a radio frequency signal generator to a human body; acquiring, as a measured respiratory signal, a respiratory signal passing through the human body and acquired in a local coil, wherein the measured respiratory signal is constituted by a real respiratory signal and an interference signal; determining, according to a respiratory signal coil sensitivity of the real respiratory signal and an interference signal coil sensitivity of the interference signal, a signal relation that is satisfied by the real respiratory signal, the interference signal and the measured respiratory signal; and calculating the signal relation to obtain the real respiratory signal.
