摘要：
An elongate electrical lead assembly that reduces localized heating due to MR scanner-induced currents includes a first elongate electrical lead having a series of alternating single layer coil sections and multi-layer coil sections, a second elongate electrical lead having a series of alternating single layer coil sections and multi-layer coil sections, and a third elongate electrical lead having a coiled section that coaxially surrounds the first and second electrical leads. Each multi-layer coil section of the second electrical lead is coiled around a respective single layer coil section of the first electrical lead, and each single layer coil section of the second electrical lead is coiled around a respective multi-layer coil section of the first electrical lead.
