A combination of CAIPIRINHA simultaneous multi-slice imaging with Compressed Sensing is presented. A technique is generated, effectively accelerating the imaging procedure in slice and phase encoding direction. Several slices are excited simultaneously and shifted with respect to each other in the FOV using RF phase cycles, while k-space is undersampled randomly in incoherent fashion. In the reconstruction process, Compressed Sensing is used to eliminate incoherent artifacts, while a parallel imaging reconstruction separates the simultaneously excited slices. The method shows potential for high quality multi-slice imaging with high acceleration factor.
