1. A method comprising:
generating, by a magnetic resonance imaging system comprising sensors arranged at positions around an imaged target volume, Low-Field-Magnetic Resonance Imaging, LF-MRI, or Ultra-Low-Field Magnetic Resonance Imaging, ULF-MRI, data with respect to an image frame;
determining, by the magnetic resonance imaging system, a sensorwise agreement of the data with determined sensitivity profiles; and
determining, by the magnetic resonance imaging system, a mapping between the image frame and a sensor frame, such that the sensorwise agreement has been fulfilled.
