A method for operating a magnetic resonance tomography system and a magnetic resonance tomography system for executing the method are provided. The magnetic resonance tomography system captures a change in state using a control system, assesses the change in state with respect to a possible operating interruption, and determines possible energy-saving scenarios for the possible imminent interruption of the image recording. The magnetic resonance tomography system captures a selection made by a user and implements the selected energy-saving scenario.

An ICA to identify a large number of candidate correlation patterns is carried out based on a time series of image data. The large number of candidate correlation patterns includes a large number of neurophysical events, as well as false patterns owing to noise. The neurophysical events as well as the false patterns are then separated, for example on the basis of a metric, which indicates an intensity of the candidate correlation patterns in a section of the brain, or by a computer-implemented classifier. Techniques of this kind can be used in conjunction with functional magnetic resonance imaging.
