Speed and accuracy of the 6-filament and the single-point models used in a simulated electromagnetic tracking experiment. Scatter plot of the error is shown in Figure 13. Computation time is calculated as the average solution time for 512 random test points.

Model	Time [s]	Distance from Board [cm]	RMSE [mm]	ME [mm]
6-filament	0.052	1–6	0.2615	0.1903
		6–11	0.0754	0.0733
single-point	0.007	1–6	1.4083	1.1024
