  • Causa
    The function of rf power monitor is to monitor the rf amplifier output power, and detect if rf transmit power exceeding the predicted amount is generated. if the rf amplifier output power exceeds the predicted sar (specific absorption rate) amount, the rf power monitor will stop the scan. if the user performs a tps (transceiver processing and storage) reset during a patient scan, the rf power monitor will be disabled for the remainder of that patient scan. this would prevent the power monitor from detecting any subsequent failure of rf transmit function. these two failures together, could result in higher than expected thermal dose to the patient and higher than expected localised heating. there have been no failures of this type reported, and no injuries reported as a result of this issue.
  • Acción
    GE Healthcare is advising users they may continue to use the system, but ensure the RF power monitor is re-enabled by initiating a new patient exam if a TPS reset is performed during a patient exam. A software upgrade will be installed as a permanent correction. This action has been closed-out on 18/05/2017.
