Radio-frequency (RF) lesioning in the
brain was simulated using the finite element method
(FEM). Heating for 60 s with temperature control in
order to keep the tip at 80 °C was simulated. Length,
L, (2 – 4 mm) and diameter, D, (0.5 – 2.5 mm) of the
electrode tip were varied and the resulting lesion
volumes were used to calculate a regression model:
Lesion Volume = – 13.1D + 15.7L⋅D + 13.1D2 mm3.
The results can be useful for electrode design and
prediction of lesion size.
