This magnetic emission device includes an antenna and further includes a device configured to select one of a plurality of predefined portions of the antenna and to connect the selected portion to a current-generating device in order both to cause the current to pass through the selected portion of the antenna so as to radiate a magnetic field, and to prevent the current from passing outside of the selected portion of the antenna.

Magnetic emission device for non-invasive cerebral magnetic stimulation

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.

Method for controlling the distribution of the RF magnetic field in a magnetic resonance imaging system

An antenna array includes a plurality of linear electromagnetic resonators having longitudinal axes oriented parallel to one another and not aligned, and at least one decoupling device arranged between two the linear electromagnetic resonators, wherein the decoupling device comprises a plurality of open-loop electromagnetic resonators that are matched to a frequency located in the bandwidth of the two the adjacent linear electromagnetic resonators, that are electrically insulated and that are arranged in a plurality of planes that are not parallel to a plane containing the longitudinal axes of the two the linear electromagnetic resonators. Nuclear magnetic resonance imaging apparatus comprising such an antenna array is also provided.
