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.
