| 20130015858 | LINEAR RESONATOR OF A HIGH-FREQUENCY ANTENNA FOR A NUCLEAR MAGNETIC RESONANCE IMAGING APPARATUSAANM Ferrand; GuillaumeAACI ParisAACO FRAAGP Ferrand; Guillaume Paris FRAANM Luong; MichelAACI SceauxAACO FRAAGP Luong; Michel Sceaux FRAANM France; AlainAACI BordeauxAACO FRAAGP France; Alain Bordeaux FR - A linear resonator of a high-frequency antenna suitable for emitting a radiofrequency energisation signal and for receiving a radiofrequency relaxation signal, the linear resonator includes a radiating element to emit a radiofrequency energisation signal and receive a radiofrequency relaxation signal. The resonator also includes: a balun circuit including a power-supply line and two coupling lines; a substrate made of a dielectric material, supporting the radiating element which contains the balun circuit; two contact points connecting the balun circuit to the radiating element, the contact points being formed by one of the ends of the coupling lines extending out of the substrate, the distance separating the two contact points being selected so as to ensure the impedance matching of the resonator; and a chip floorplan separating the coupling lines from the radiating element. | 01-17-2013 |
