Figure 5.

Beamformer (SAM) reconstruction inaccuracies as mere consequence of geometrical modeling imprecision if based on realistic sensor coverage (10‐10 system): An isotropically conducting FE model has been used for the forward solution while the inverse reconstruction was based on an isotropically conducting spherical head model. The left column illustrates the reconstruction results for each simulated dipole as three‐dimensional field of displacement vectors (cones). The right column visualizes the superficial reconstruction errors as projection to the outer skin surface.
