It is shown how the fields derived upon singular value decomposition are related to the true receive and transmit fields maps of a pTx coil array. TRIPLET produces all necessary RF field maps for a parallel transmit and parallel imaging experiment in a very short time and with use of minimal RF power. In addition, the methods results in receive sensitivity maps per channel without the need for a homogeneous receive reference. The method is generic and will also work in case of a single transmit channel combined with several receive channels.
