The five point method (FPM) for approximating Laplacian potentials sharply attenuates the potentials due to sources far from the surface electrodes. Similar attenuation is achieved if nine points are used in a variation of the FPM. There is a difference in the attenuation characteristics of the FPM and nine point method (NPM) since the nine points cover more space than the five points. As a result the FPM and NPM behave differently for a dipole source at any specific depth giving rise to quantization of dipole depths. This quantization of depth can be used to determine the depth of the bioelectrical sources from the surface potential measurements. Direct depth perception will be helpful in non-invasive 3D imaging.
