Look Ahead monitoring: Prior to each measurement, the values of
the SAR quantities to be observed are calculated (always as worst-
case values) and compared with the corresponding limit values. If one
of the calculated SAR values exceeds the corresponding limit, the
measurement cannot be started. The following message appears in
the dialog window of the syngo Acquisition Workplace: SAR Limit(s)
Exceeded!

To ensure correct calculation of the SAR values, the weight of the
patient must be entered during registration.
This dialog window includes suggested changes to the examination
parameters which allow the examination to continue. In addition, a
button in the dialog window may be used to change the operating
mode.

In the First Level Controlled Operating Mode, often only minor
modifications (if any) may be required.
