Abstract
A transmission path (2) comprising an electrically conductive link or connection lead or line or cable (21) is disclosed, which path is or can be made RF safe (especially with respect to heating due to standing waves) when guided through RF electrical and/or magnetic fields especially of a MR imaging system and which is especially suitable for connecting a base or connection unit (1), like for example a power supply or a control or evaluation unit (first unit), with a distal or remote electrical unit (3) like a sensor or a detector, a transmit and/or receive unit, or an accessory device like for example an RF body or surface coil system, or an invasive or interventional device like for example a catheter or implantables (second unit), especially in a magnetic resonance (MR) imaging system. The transmission path may comprise pressure switches or optical switches.
