  • Method for controlling the distribution of the RF magnetic field in a magnetic resonance imaging system
    Patent number: 10816620
    Abstract: A method for controlling the distribution of the RF magnetic field in a magnetic resonance imaging system, having steps of: placing a cage coil in a permanent magnet supplying a permanent magnetic field along a first axis, and supplying an RF signal to the cage coil in order for the coil to generate an RF magnetic field rotating in a plane that runs perpendicular to the first axis; and putting in place an electromagnetic resonator, the resonance mode of which is excited by the rotating magnetic field, the resonator being placed in a position inside or outside the cage coil and at a distance from a region to be analyzed of an object to be placed in the cage coil, the resonance mode and the position of the resonator in relation to the volumetric antenna being suitable for adjusting the intensity of the rotating magnetic field in an area of the region to be analyzed.
