Comprehensive characterization of an RF resonator is given by a quantitative and spatial analysis of its magnetic field produced per unit current (B1unit+). In this study, we present an extension of the multi-flip-angle approach which allows mapping of inhomogeneous B1unit+ fields in three dimensions over a large dynamic range. To demonstrate its superiority over the commonly-used conventional double-angle method, a comparison between both is given.
