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 artifacts.

摘要： A fiducial position marker (1) for use in a magnetic resonance (MR) imaging apparatus is disclosed for exciting and/or receiving MR signals in/from a local volume which at least substantially surrounds or adjoins the position marker, in order to determine and/or image from these MR signals the position of the position marker in an MR image of an examination object. Such a position marker (1) is especially used for determining and/or imaging a position of an interventional or non-interventional instrument to which the position marker may be attached like a catheter, a surgical device, a biopsy needle, a pointer, a stent or another invasive or any non-invasive device in an MR image of an examination object. Further, a position marker system comprising such a position marker (1) and a circuit arrangement (5,6,6a,8) for driving the position marker (1) for exciting MR signals and/or for processing MR signals received by the position marker is disclosed.
