摘要：
An electrically conductive transmission cable for supplying a DC signal safely to an electrical device in the presence of radio-frequency (RF) fields in a magnetic resonance (MR) is disclosed herein. The transmission cable comprises a transmission line (STL) comprising at least a first segment (S1) and a second segment (S2), wherein the first and second segments are electrically connected to each other by a reactive coupling unit (103), and a rectifier unit (101) connected to the transmission line and configured to extract the DC signal (203) from the modulated DC signal (201). The extracted DC signal may be supplied to an electrical device or used for cardiac pacing. The transmission cable finds application in auxiliary devices used in an MR environment, for example an interventional catheter with or without an active tracking circuit (301).
