We propose a concept for targeted bilateral breast imaging. A practical demonstration of the concept features a pair of hollow dielectric cylindrical resonators based on a composite material with very high permittivity. The resonators are electromagnetically coupled to the body birdcage coil and each other. Electromagnetic simulations demonstrated that symmetric B1+ field mode, inherent in interacting resonators, can be efficiently excited at 123 MHz via the body birdcage coil. Simulations with realistic voxel models let us estimate transmit efficiency and radiofrequency safety of the proposed device and demonstrated that the concept promising for clinical applications.
