A computer is supplied with information about a measurement sequence to be implemented by a medical imaging system, and determines at least one group of preliminary control sequences for power supply devices of the medical imaging system so that the power control devices are caused to control image-influencing emission devices of the imaging medical system corresponding to the control sequences. Using a model of the image-influencing emission devices and their respective power control devices, and their respective initial load state, the computer determines whether a load state curve for those devices is below a load limit, and emits a final control sequence for those devices that are determined to be below the limit.
