In this work, a model based reconstruction method for accelerated 3D B1+ mapping is illustrated. Only a limited number of transverse slices is needed as input for the reconstruction problem, reducing the scan time up to a factor 5. Positive results from simulations and in vivo measurements confirm the validity of the method.
