  • MRI system, method for determining SAR value of MRI system, and computer-readable storage medium
    Patent number: 11876549
    Abstract: In the present invention, provided are a magnetic resonance imaging system, a method for determining a SAR value of a magnetic resonance imaging system, and a computer-readable storage medium. The system comprises 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. The system further comprises a reflection coefficient determining module, a resistance value determining module, and a SAR value determining module. The reflection coefficient determining module is configured to acquire a frequency response of a first input reflection coefficient of the radio-frequency transmitting coil when having no load and a frequency response of a second input reflection coefficient thereof when having the scanned object.
