Modeling of electric field distribution in tissues during electroporation

Table 4 Calculated R ² between IA, NPA and SA and in vivo data - needle electrodes

	Electrode diameter
	1.1 mm	0.7 mm	0.3 mm
Analysis type with σ_L(E)	R²:
IA with linear σ_L(E)	0.883214	0.875605	0.92873
NPA with smoothed Heaviside σ_L(E)	0.9192
NPA with sigmoid σ_L(E)	0.8964
SA with sigmoid σ_L(E):	0.8938

* The calculated R² for SA is given for the σ_L(E) with 5 discretization steps. The calculated R² for models with σ being independent of E (σ_L = const. = 0.04593 S/m and σ_L = const. = 0.067 S/m) was negative.
The calculated goodness-of-fit measure R² between numerical data obtained with nonlinear model (model with σ_L(E)) and in vivo data.
