MRI-COMPATIBLE 12-LEAD ECG CABLE

摘要

An apparatus and method for an electrocardiogram (ECG) cable suitable for use inside a Magnetic Resonance (MR) scanner during a Magnetic Resonance Imaging (MRI) operation. In particular, the present invention relates to a patient safe (MRI-conditional) 12-lead ECG cable capable of use inside an MR scanner during an MRI scan. The ECG cable does not heat up to a degree that would burn a patient undergoing an MRI scan, but also enables the conventional 12-lead ECG electrode placement required for diagnostic monitoring of the patient. Specifically, the ECG cable electrodes can be placed on a patient in the traditional configuration as 12-lead ECG cable designed for use outside of an MR scanner and take diagnostic level readings, during operation of an MR device or system. Additionally, the cable provides a continuous shield which maintains zero emissions while satisfying defibrillation requirements.

主权项

1. An Electrocardiography (ECG) cable bundle, comprising:
a plurality of signal leads having proximal ends and distal ends; a plurality of electrodes electrically coupled to the distal ends of the plurality of signal leads, each of the plurality of electrodes being electrically coupled to a different one of each of the plurality of signal leads; a yoke electrically and mechanically coupled to a first end of a cable trunk; a plurality of connectors disposed at the proximal ends of the plurality of signal leads, the plurality of connectors electrically and mechanically coupled to the yoke; a proximal connector electrically and mechanically coupled to a second end of the cable trunk; at least one Radio Frequency (RF) balun interposed on each of the plurality of signal leads between the plurality of electrodes and the yoke; and at least one RF balun interposed on the cable trunk between the yoke and the proximal connector.
