Abstract
A magnetic resonance (MR) safe cable (10) includes four or more controlled resistance electrically conductive wires (12) disposed in a parallel planar configuration, and a stiff non-proton emitting substrate (14) which holds the four or more controlled resistance conductive wires in the parallel planar configuration. The wires (12) terminating at one end in connectors which electrically connect to ECG electrodes (64) which are attached to the subject. The cable is configured to extend the one end into an imaging region of an MR scanner (62) during imaging to carry ECG signals to associated equipment.
Claims20
A magnetic resonance safe cable, comprising:
- four or more electrically conductive wires disposed in a planar configuration and parallel to each other;
- and
- a stiff non-proton emitting substrate which holds the four or more controlled resistance conductive wires in the planar configuration and parallel to each other;
- wherein the stiff substrate includes a flat foam jacket which surrounds and holds the conductive wires parallel and in the common plane.

A method of using a magnetic resonance safe cable, comprising:
- attaching at least four electrodes to a subject;
- disposing the MR safe cable along the subject supported by the subject or a subject support, the MR cable including at least four conductive wires disposed in a parallel planar configuration and housed in a foam jacket;
- connecting a connector attached to one of the corresponding connectors of a first end of the at least four conductive wires to the electrodes;
- connecting connectors attached to a second end of the conductive wires to a patient monitor;
- and
- with a stiff non-proton emitting substrate of the MR safe cable which encases the conductive wires in the parallel planar configuration, holding the four or more controlled resistance conductive wires in the planar and parallel configuration.
A method of manufacturing a magnetic resonance safe cable, comprising:
- stretching at least four electrically conductive wires parallel and in a plane;
- coating the stretched at least four electrically conductive wires with a stiff foam jacket.
