1. A method for simulating a diagnostic magnetic resonance image of an examination subject, said diagnostic image of the examination subject being obtained with a magnetic resonance data acquisition system, said method comprising the steps of: for a diagnostic magnetic resonance image that will be obtained from an examination subject using a magnetic resonance data acquisition system, determining imaging parameters for an imaging sequence that will be used to operate the magnetic resonance data acquisition system to obtain the diagnostic magnetic resonance image; determining at least one item of anatomical information of the examination subject; determining signal-to-noise information of said magnetic resonance data acquisition system; in a processor, automatically simulating a simulated magnetic resonance image in real time, dependent on the determined imaging parameters, the determined anatomical information and the determined signal-to-noise information; and visually displaying the simulated magnetic resonance image.
