Patent ID: 8571630

Claim:
An electrically conductive transmission line for transmitting magnetic resonance RF signals between a transmission or receiving coil and a transmitting or receiving unit, comprising a plurality of lead segments coupled only by transformers having a transformer impedance Z L placed between two neighbouring lead segments, wherein for power matching of the two transformers placed at opposite ends of a lead segment, the lead segment has a lead segment impedance Z 0 or a dielectric constant ∈ r and wherein the length l of the lead segment is determined by l = 1 β ⁢ arc ⁢ ⁢ tan ( - 2 ⁢ ⁢ Im ⁡ ( Z L ) ( Z 0 -  Z L  2 Z 0 ) ) where β = 2 ⁢ π / λ , λ = λ 0 ɛ r and λ 0 is the wavelength of the magnetic resonance signals in a vacuum.
