摘要： The present invention relates to a device (100) and method for interfacing a signal transmission/reception device (200) and a catheter (300). A signal transmitted by the signal transmission/reception device (200) and supplied to the device (100) via a first interface (102, 104, 106, 108) can be sensed by a first sensor (114). The sensed signal may be adjusted by an adjustment unit (116). The adjusted signal can be output via a second interface (110, 112) and supplied to the catheter (300). In this way, a resistance loss caused by a conductor (302, 304) of the catheter (300) may be compensated for.

摘要： An electrically conductive transmission line for transmitting RF signals, in particular for transmitting MR signals between a transmission and/or receiving coil and a transmitting and/or receiving unit, by which separate known matching networks can be avoided or reduced. A transmission line is proposed comprising a plurality of lead segments coupled by transformers having a transformer impedance ZL placed between two neighboring 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 Z0 or a dielectric constant ∈r and wherein the lead segment has a short length l. Thus, the lead segments themselves provide the matching of the transformers, and separate matching circuits are no longer needed.

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).
