Method for improved recording of scan data of an examination object by means of a magnetic resonance system with the aid of a simultaneous multi-slice method using at least two receiving coils, wherein magnetic resonance signals are recorded in at least two slice groups of different slices of the examination object, wherein slices included by a slice group are recorded simultaneously during a recording of MR signals (MD i), comprising the steps: - loading a scan protocol with which the MR signals are to be recorded and which comprises a slice stack to be recorded, an SMS factor F to be used during the recording and at least one quality criterion, - determining a minimum repetition time TR dependent upon the at least one quality criterion, - calculating a number K of slices from which MR signals can be recorded with a number M of possible excitations and recordings of MR signals of a slice group within the determined minimum repetition time, said number M being determined on the basis of a slice group scan time specified by the scan protocol for exciting and recording MR signals of a slice group and of the determined minimum repetition time TR, - determining multi-band RF pulses (MB 1...MB M) for exciting M slice groups each comprising F slices which altogether comprise the slice stack to be recorded, - recording MR signals (MD i) using the multi-band RF pulses (MB i) within the determined minimum repetition time, - loading slice separation calibration data for the slice stack to be recorded, - separating the MR signals (MD i) of the slice groups respectively into single slice MR signals (MD i1...MD iF) of the individual slices included by the slice groups making use of the slice separation calibration data, - generating image data (BD ij) of at least one slice included by the slice stack to be recorded, by reconstruction of the single slice MR signals (MD i1...MD ik) of the slice, wherein, on the basis of the determined number K and on the basis of the scan protocol, a number of excess slices and their respective slice positions are determined, and wherein, in the determination of the multi-band RF pulses (MB 1...MB M) for excess slices, a reduced flip angle of approximately 33% of a corresponding non-reduced value of a flip angle to be used specified for non-excess slices, or less is specified. - loading a scan protocol with which the MR signals are to be recorded and which comprises a slice stack to be recorded, an SMS factor F to be used during the recording and at least one quality criterion, - determining a minimum repetition time TR dependent upon the at least one quality criterion, - calculating a number K of slices from which MR signals can be recorded with a number M of possible excitations and recordings of MR signals of a slice group within the determined minimum repetition time, said number M being determined on the basis of a slice group scan time specified by the scan protocol for exciting and recording MR signals of a slice group and of the determined minimum repetition time TR, - determining multi-band RF pulses (MB 1...MB M) for exciting M slice groups each comprising F slices which altogether comprise the slice stack to be recorded, - recording MR signals (MD i) using the multi-band RF pulses (MB i) within the determined minimum repetition time, - loading slice separation calibration data for the slice stack to be recorded, - separating the MR signals (MD i) of the slice groups respectively into single slice MR signals (MD i1...MD iF) of the individual slices included by the slice groups making use of the slice separation calibration data, - generating image data (BD ij) of at least one slice included by the slice stack to be recorded, by reconstruction of the single slice MR signals (MD i1...MD ik) of the slice, wherein, on the basis of the determined number K and on the basis of the scan protocol, a number of excess slices and their respective slice positions are determined, and wherein, in the determination of the multi-band RF pulses (MB 1...MB M) for excess slices, a reduced flip angle of approximately 33% of a corresponding non-reduced value of a flip angle to be used specified for non-excess slices, or less is specified.
