In this work we present a new approach for extracting complete complex information about the transmit and receive fields of a RF transmit coil from a B1+ amplitude measurement. The method is based on a Bessel/Fourier modes expansion of the B1+ and B1- maps. The results obtained from FDTD simulations and in vivo measurements confirm the validity of the novel approach.
