CONTROL OF A RADIO-FREQUENCY AMPLIFIER OF A MAGNETIC RESONANCE SYSTEM

摘要

A method for control of a radio-frequency amplifier of a magnetic resonance system is provided. The method includes determining a radio-frequency power to be output by the radio-frequency amplifier during an examination of a patient in the magnetic resonance system. Using a Lambert W function, a maximum temperature in tissue of the patient is determined as a function of the radio-frequency power. The radio-frequency amplifier is set as a function of the maximum temperature.
