This work describes the design, construction, and performance of a 32-channel array coil for bilateral breast imaging at 7T. Imaging indicated an increase in average SNR over a T/R volume coil of 5.5 times, with a three times increase in the center and up to 20 times along the periphery. Channel noise correlations indicated well decoupled elements and highly unilaterally isolated sets of 16 elements. In combination with high field strength benefits, this array will enable high resolution accelerated breast imaging.
