Claim 7:
8. The system according to claim 1, wherein
the frequency response of the first input reflection coefficient comprises: a frequency response of the first input reflection coefficient at a resonant frequency of the radio-frequency transmitting coil when the radio-frequency transmitting coil has no load;
the frequency response of the second input reflection coefficient comprises: a frequency response of the second input reflection coefficient at a resonant frequency of the radio-frequency transmitting coil when the radio-frequency transmitting coil has the scanned object;
the resistance value determining module is further configured to:
calculate the resistance value of the radio-frequency transmitting coil on the basis of the frequency response of the first input reflection coefficient at the resonant frequency and an intrinsic impedance of the radio-frequency transmitting link; and
calculate the parallel resistance value on the basis of the frequency response of the second input reflection coefficient at the resonant frequency and the intrinsic impedance of the radio-frequency transmitting link.
