FIELD: electricity. ^ SUBSTANCE: electrically conducting line (13) for transmission of magneto-resonance signals between transmitting and/or receiving coil (11) and transmitting and/or receiving unit (12) contains multiple portions (31) of conductor, connected by transformers (32, 33) only having transformer impedance ZL and located between two adjacent portions of conductor. Herewith, to match powers of two transformers (32, 33) located on opposite ends of conductor portion (31) the mentioned conductor portion (31) has low impedance Z0 of conductor portion and/or high dielectric constant r and where length l of the mentioned conductor portion (31) is determined from: where =2Ç/, and 0 - wavelength of magnetic-resonance signals in vacuum. ^ EFFECT: preventing generation of in-phase signal on cable armoring. ^ 8 cl, 4 dwg |
