Simultaneous multi-slice (SMS) acquisition of measurement data by means of magnetic resonance technology

A magnetic resonance (MR) system for acquisition of measurement data from an object under examination, comprising:

• a magnet;
• gradient circuitry;
• radiofrequency (RF) generation circuitry;
• and
• control circuitry configured to:
• cause the RF generation circuitry to generate a plurality of multiband RF pulses, with one multiband RF pulse being generated for each one of at least two slice groups to simultaneously manipulate spins of slices contained in each one of the at least two slice groups to cause the multiband RF pulse associated with at least two slice groups to have a signal intensity profile that differs from one another;
• acquire, using a simultaneous multi-slice (SMS) technique, MR signals from each one of at least two slice groups from different slices of the object under examination using the plurality of multiband RF pulses;
• separate the MR signals of the at least two slice groups into single-slice MR signals associated with individual slices contained in each one of the at least two the slice groups;
• and
• produce image data for a slice contained in the at least two slice groups by reconstructing the single-slice MR signals of the respective slice.

A non-transitory computer readable medium having instructions stored thereon that, when executed by a controller of a magnetic resonance (MR) system, cause the MR system to:

• generate a plurality of multiband RF pulses, with one multiband RF pulse being generated for each one of at least two slice groups to simultaneously manipulate spins of slices contained in each one of the at least two slice groups to cause the multiband RF pulse associated with at least two slice groups to have a signal intensity profile that differs from one another;
• acquire, using a simultaneous multi-slice (SMS) technique, MR signals from each one of at least two slice groups from different slices of the object under examination using the plurality of multiband RF pulses;
• separate the MR signals of the at least two slice groups into single-slice MR signals associated with individual slices contained in each one of the at least two the slice groups;
• and
• produce image data for a slice contained in the at least two slice groups by reconstructing the single-slice MR signals of the respective slice.
