Homogeneous excitation and reception provides a much better base for in vivo absolute quantification of cells and drugs levels with respect to inhomogeneous signal distribution. In this work we present a Helmholtz pair that is capable of generating a homogeneous transmit field at both 1H and 19F at 3T. To obtain signals with high SNR and optimal coverage over the liver and lymph nodes two dedicated multiple element receive coils were developed.
