  • RF surface resonator for a magnetic resonance imaging apparatus
    Patent number: 6710598
    Abstract: The invention relates to an RF surface resonator (RF coil) for transmitting and/or receiving circularly polarized electromagnetic waves, which resonator is intended in particular for magnetic resonance imaging (MRI) apparatus in which a basic magnetic field (vertical field) that extends perpendicularly through an object to be examined and a circularly polarized RF field are generated. Various steps are proposed so as to achieve a desired variation of the field strength in the radial direction as well as in the direction of circulation.
    Type: Grant
