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

From: Modeling of electric field distribution in tissues during electroporation

  Electrode diameter
  1.1 mm 0.7 mm 0.3 mm
Analysis type with σL(E) R2:
IA with linear σL(E) 0.883214 0.875605 0.92873
NPA with smoothed Heaviside σL(E) 0.9192   
NPA with sigmoid σL(E) 0.8964   
SA with sigmoid σL(E): 0.8938   
  1. * The calculated R2 for SA is given for the σL(E) with 5 discretization steps. The calculated R2 for models with σ being independent of E (σL = const. = 0.04593 S/m and σL = const. = 0.067 S/m) was negative.
  2. The calculated goodness-of-fit measure R2 between numerical data obtained with nonlinear model (model with σL(E)) and in vivo data.
