1. A coil decoupling method for a magnetic resonance imaging device, the magnetic resonance imaging device comprising a transmitter, a receiver, a decoupling component and a plurality of coils, the method comprising:
sending an instruction causing the transmitter to send a transmitted signal;
acquiring a received signal received by the receiver, wherein the received signal is the transmitted signal that arrives at the receiver after passing through two coils to be adjusted of the plurality of coils, wherein one of the two coils to be adjusted is a transmitting coil operable to receive the transmitted signal sent by the transmitter, and the other of the two coils to be adjusted is a receiving coil operable to receive the signal sent by the transmitting coil;
determining a coupling value between the two coils to be adjusted based on the transmitted signal and the received signal; and
in response to a determination that the coupling value is less than a coupling threshold, sending an instruction for adjusting the decoupling component based on the coupling value, updating the coupling threshold with the coupling value, and sending another instruction causing the transmitter to send another transmitted signal.
