In a method and control device for magnetic resonance imaging, raw magnetic resonance data are acquired from one region of an examination object by a number of magnetic resonance receiving antennas of a magnetic resonance system. Calibration values are determined that represent the sensitivity of at least one of the magnetic resonance receiving antennas. An image reconstruction is performed on the basis of the raw magnetic resonance data, taking into consideration the determined calibration values. The determination of the calibration values is frequency-dependent.
