Classification: CPC H  G | IPC G  H

Claim 3:
4. The system according to claim 2, wherein the SAR value determining module is further configured to:
receive the second forward signal and the second reverse signal that are currently detected, and calculate, on the basis of the second forward signal and the second reverse signal that are currently detected, total radio-frequency power currently absorbed by the radio-frequency transmitting coil and the scanned object;
calculate the proportion of radio-frequency power absorbed by the scanned object in the total radio-frequency power on the basis of a ratio of a resistance value of the scanned object to the resistance value of the radio-frequency transmitting coil, wherein the resistance value of the scanned object is calculated on the basis of the parallel resistance value and the resistance value of the radio-frequency transmitting coil; and
calculate the SAR value of the scanned object on the basis of the total radio-frequency power, a weight of the scanned object, and the proportion.
