Fig 5: Tissue substitution analysis for passive and active heating conditions in SCS model.

Fig 5:

Predicted ΔT and EF were reported in both absolute scale (data sampled at a radial distance equal to the surface of spinal cord from the surface of epidural fact, represented by a gray dot) and relative scale (data sampled at a corresponding tissue surface for all tissue combination as illustrated in the figure) from parasagittal spinal tissue slice. On an absolute scale for both passive and active heating conditions, ΔT and EF decreased as more tissues were added around the epidural fat. With an entire tissue combination (A5, B5) on this scale, the ΔT and EF were 0.84°C and 17.76 V/m in passive heating and 0.37 °C and 17.76 V/m in active heating. Similarly, on the relative scale for passive and active heating conditions, ΔT and EF decreased as more tissues were added. Maximum ΔT (7.65 °C) and EF (9.9 KV/m) were reported around the lead with only epidural fat (A1, B1, relative scale). As more tissues were added, ΔT around the lead decreased to 3.88 °C in passive heating and 3.67 °C in active heating. Maximum predicted ΔT and EF at the spinal cord was 0.37 °C and 17.76 V/m with the entire tissue combination (A5, B5, relative scale).
