The possibility of high local SAR values can be a limiting factor to in-vivo transmit-SENSE applications at high field. In this work we introduce a novel method to reduce the local SAR and demonstrate its application based on simulations. When considering the human head at 7T, the proposed method demonstrates local SAR reductions up to a factor of 6.
