✦ Synopsis

To understand the behavior of many NMR experiments, it is important to determine the spatial distribution of the B 1 field. In this paper, we show how this distribution can be mapped independently of spin density, coil responsiveness, and nonlinearities of the B 0 field gradients. As a by-product we obtain a map of the (possibly nonlinear) spatial variation of the B 0 field gradients used in the imaging procedure.
