Online monitoring: The system constantly measures the transmit
power and ensures that the appropriate limit values are observed.
Examinations in progress will be aborted if the limit is exceeded.
Limit values: The SAR limits used by the Look Ahead monitoring
function are set according to country-specific approval guidelines at
the time of the syngo MR installation.
Normal operating mode: In the Normal Operating Mode, the patient
barely notices the effects of the RF field. The stress on the cardio-
vascular system is negligible.
First Level Controlled Operating Mode: In the First Level Controlled
Operating Mode, patients may experience noticeable stress levels
depending on the measurement programs selected. This usually
includes perspiration accompanied by an increase in pulse rate.
Patients with reduced thermoregulatory capability and higher
sensitivity toward increases in body temperature (e.g. patients with
fevers or cardiac decompression, patients with perspiratory
impairments, or pregnant women) may experience additional effects.
Display of SAR values: The current SAR values, encoded according to
the body regions of interest, can be accessed at any time. See:
