Abstract: 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.
