A refinement of the DREAM B1+ mapping technique is presented, that removes the potential T1-bias from the B1+ maps. It is based on a phase cycling scheme including adiabatic inversion pulses and improves the B1+ mapping accuracy and reliability and extends the dynamic working range of the DREAM approach. The method has been successfully validated on phantoms and in vivo on the brain at 3T.
