Abstract
A method for recording a B0 map of a main magnetic field of a magnetic resonance device in an imaging volume of which an object to be recorded is arranged includes scanning a recording region to be covered by the B0 map by the magnetic resonance device. The recording region is scanned by a map recording sequence slice-by-slice in successive slices in a slice selection direction extending in a phase encoding direction and a readout direction, or three-dimensionally using two phase encoding directions and one readout direction in order to ascertain the B0 map. In a preliminary scan, the magnetic resonance device ascertains extension information describing the extension of the object using a scout sequence, which is used to define the recording region in sequence parameters of the map recording sequence and/or to adjust at least one sequence parameter of the map recording sequence.
