A method for carrying out magnetic resonance measurements on an examination object in a magnetic resonance system is described. In at least one embodiment, a magnetic resonance image of the examination object previously acquired via the magnetic resonance system is used to determine spatial coordinates in order to control the magnetic resonance system for the magnetic resonance measurement to be carried out. In this case, in order to determine the spatial coordinates, use is made of a distortion-corrected magnetic resonance image generated on the basis of an original magnetic resonance measured image acquired by the magnetic resonance system and transformed in advance into an equivalent measured image on the basis of field inhomogeneity values of the magnetic resonance system. Also described are a method for, in at least one embodiment, transforming a distortion-corrected magnetic resonance image, generated on the basis of an original magnetic resonance measured image acquired by a magnetic resonance system into an equivalent measured image, and a suitable image transformation unit.
