ABSTRACT:
In a method, device and magnetic resonance tomography system for monitoring a radio-frequency apparatus in which radio-frequency pulses are emitted at temporal intervals and in which measurement values representing the power of the radio-frequency pulses are measured at temporal intervals, the measurement values are used to determine exposure values that represent a physiological effect that the radio-frequency pulses have on a subject exposed to the radio-frequency pulses. Based on a number of exposure values, exposure-monitoring values are respectively formed and the radio-frequency apparatus is limited in function if an exposure-monitoring value reaches or exceeds an exposure limit value.
