A spatially invariant 2D navigator acquired simultaneously using multi-band excitation pulses is proposed and demonstrated for multi-slice free-breathing liver imaging. Using the 2D navigator 3D reconstructions of the liver at different respiratory positions are possible hence allowing assessment of respiratory-induced tissue deformations to aid for instance radio-therapy planning.
