Simultaneous multi-slice imaging has been employed for the DREAM B1+ mapping approach, allowing a multi-slice B1+ map to be acquired in a fraction of a second. Basic feasibility has been shown in experiments on phantoms and in vivo using a clinical 3T MRI system. The presented approach potentially allows free-breathing multi-slice B1+ mapping, freezing respiratory motion in a short single shot acquisition window.
