Classification: CPC H  G | IPC G  H

Claim 19:
20. A magnetic resonance imaging system, comprising:
a radio-frequency transmitting coil, configured to receive radio-frequency power from a radio-frequency transmitting link and transmit radio-frequency power required for imaging to a scanned object;
a resistance value determining module, configured to determine a ratio of resistance values of the radio-frequency transmitting coil and the scanned object; and
a SAR value determining module, configured to determine total radio-frequency power absorbed by the radio-frequency transmitting coil and the scanned object when the radio-frequency power is transmitted to the radio-frequency transmitting coil, and calculate a SAR value of the scanned object on the basis of the ratio and the total radio-frequency power.
