Abstract: The invention relates to a module (6) for producing an MRI and/or MRS reference signal (S0), characterized in that the module comprises: a first receiving input (621) for receiving of an MRI and/or MRS synchronization signal (S3), a second receiving input (612) for receiving of a time signal (S8) of external stimulation, supply means (62) for supplying of a prescribed signal (RV) representing an MRI and/or MRS virtual object (RVV), generating means for generating of the MRI and/or MRS reference signal (S0), for temporally varying the MRI and/or MRS reference signal (S0) in the same way as a time characteristic determined from the time signal (S8) of external stimulation and in synchronization with the MRI and/or MRS synchronization signal (S3), a supply output (632) for supplying of the MRI and/or MRS reference signal (S0).
