A dielectric resonator made from a high permittivity low loss barium strontium titanate has been designed to operate in degenerate quadrature HEM11 modes at 298.1 MHz (7 Tesla). The compact resonator was designed for high resolution imaging of human digits with a high filling factor and patient comfort. New methods of double tuning such a resonator to proton/fluorine are also presented.
