摘要： The invention relates to electrophysiology catheter systems and their use, such as in an MRI environment, and in particular to analysis of electric signals from such. An electrophysiology (EP) catheter with a plurality of electrically isolated electrode segments arranged in longitudinally spaced bands around the catheter is used to detect electric signals. A workstation receives the electrical signals which are then processed by a processing unit. Electric signals from electrode segments can be used to determine roll angle information of the catheter in relation to patient anatomy by determining signals from electrode segments in contact with tissue. Also, electric signals can be used to extract a reference signal that can be used to correct for gradient induced artefacts.

摘要： The present invention relates to an electrically conductive transmission line for transmitting RF signals, in particular for transmitting MR signals between a transmission and/or receiving coil (11) and a transmitting and/or receiving unit (12), by which separate known matching networks can be avoided or reduced. A transmission line is proposed comprising a plurality of lead segments (31) coupled only by transformers (32, 33) having a transformer impedance ZL placed between two neighbouring lead segments, wherein for power matching of the two transformers (32, 33) placed at opposite ends of a lead segment (31) said lead segment (31) has a low lead segment impedance Zo and/or a high dielectric constant εr and wherein said lead segment (31) has a short length 1. Thus, the lead segments themselves provide the matching of the transformers, and separate matching circuits are no longer needed.
