Abstract

The disclosure relates to simulating an electrical stimulation during an examination of an examination object, in which the examination object is examined in a MR system to create a MR image using an imaging sequence, where a time characteristic of at least one magnetic field gradient used during the imaging sequence is determined, a time derivative of the time characteristic of the at least one magnetic field gradient is determined, and change time points at which the value of the time derivative changes are determined. The simulation of the electrical stimulation for the imaging sequence is performed, wherein the simulation is restricted to the determined change time points.
