A novel multi-slice B1 mapping approach dubbed DREAM (Dual Refocusing Echo Acquisition Mode) is proposed, which derives a 2D B1 map from a single, ultra-short acquisition of about 130 ms duration, which is more than an order of magnitude faster than most existing B1 mapping techniques. Moreover, the B1 phase and B0 are delivered additionally for free. The performance of the approach is demonstrated in vivo by B1 mapping experiments of brain and abdomen at 3T.
