Abstract
A computer-implemented method for estimating an influence of a magnetic resonance tomography sequence on at least one component in or on an examination tunnel of a magnetic resonance tomography system, wherein the method comprises inputting at least one gradient waveform of the magnetic resonance tomography sequence into a temperature model; calculating an increase in temperature caused by an application of the magnetic resonance tomography sequence in the at least one component using the temperature model, the temperature model configured to calculate the increase in temperature based on an estimation of eddy currents induced by the at least one gradient waveform in the at least one component; and outputting at least one of the calculated increase in temperature or a temperature achieved by the increase in temperature.
