Figure 14. Temperature distribution at the end of stimulation for varied stimulation intensity from 20 mA to 40 mA.

Figure 14

(A–D) The stimulation intensity is 20 mA. (E–H) The stimulation intensity is 30 mA. (I–L) The stimulation intensity is 40 mA. (A, E, I) The temperature distributions on the cross-sectional surface for different stimulation intensities. (B, F, J) The magnified view of the hot area (circled in (A, E, I) respectively), i.e. the skin and fat layers. (C, G, K) The temperature distribution of the abdomen, muscles and the vertebrae. (D, H, L) Shows temperature distribution of the vertebrae, epidural fat, CSF, WM, and GM. The stimulation electrode side length is 1 cm, and the blood perfusion rate of the dermis and WM/GM are 0.025 s−1 and 0.012 s−1 respectively. The maximum and minimum temperature values are shown with the corresponding color bars in each panel. Unit: °C.
