This work is devoted to a wireless power transfer in magnetic resonance imaging (MRI) at a higher-order mode of a birdcage resonator. A numerical model of the resonator with a phantom and the Siemens Avanto 1.5 T clinical MRI scanner have equal parameters. We use two orthogonally located loop antennas as a system of receiving antennas. In the course of numerical simulations of the voltage on the receiving antenna system, electric and magnetic field distribution, and the specific absorption rate (with a detailed voxel model of a human), we found that the optimal mode is at a frequency of 44.2 MHz. Ways of the practical application of the wireless power transfer system presented.
