This work evaluates the suitability of various pathway models to represent the worst-case heating for a Spinal Cord Stimulation lead when subjected to MRI RF-intensive exposure. The ideal model represents relevant pathways that a lead can take between any two points with the fewest variable factors. One model, used for evaluation of safety for Spinal Cord Stimulation (SCS) devices, describes a path with 4 variable factors – IPG starting position (Z), vertical rise of the proximal end of the lead (H1), lateral span width (W), and rise of the distal end of the lead within the central axis (H2). The “right angle” model is evaluated direct diagonal, half-way diagonal, and one in which all vertical rise is confined to the central axis of the MRI.
