A quadrature volume transmit coil for breast imaging and spectroscopy at 7 Tesla is discussed. The Helmholtz-saddle coil configuration utilizes "Forced Current Excitation" to ensure equal current at the feed point of each element in each array. Results demonstrate excellent B1 homogeneity and validate the design for use at 7T.
