Zusammenfassung:In a 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 (SMS) method, a minimum repetition time TR is determined dependent upon a quality criterion. The quality criterion herein extends the scan time, which is actually greatly shortened by the use of an SMS method, for the MR signals of the slice stack to be recorded, to the minimum repetition time TR. The "time reserve" thereby obtained (the difference of the determined minimum repetition time TR from the scan time needed for the slice stack to be recorded purely by means of the SMS method) is utilized to take account of further slices in the recording of the MR signals. By this means, firstly, further information can be obtained and, secondly, the image quality of the image data obtained is improved.
