8 channel transmit array is used to reduce the SAR around a generic implant model in a uniform phantom. For this purpose, implant friendly modes of the transmit array are generated. Using these modes, the optimum least square 3-spokes pulse design solution is calculated with an optimization approach which explicitly constrains both global and local SAR.
