Abstract:
A method for monitoring an exposure experienced by a patient during an examination with a magnetic resonance device having a transmitter device is provided. The method includes determining a coil power loss from measured amplitudes and phases of a first measuring device, and determining an overall transmitted power from voltage measurement values of the second measuring device. The method also includes determining a specific absorption rate (SAR) value describing a power entering a patient from the coil power loss and the overall transmitted power and comparing the SAR value with at least one limit value. A transmission operation of the transmitter device is terminated if the at least one limit value is exceeded.
