Abstract

A numerical solution of a model of the bioelectric field of the e.r.g. was developed utilising a finited-difference successive overrelaxation technique. The difference equations implemented by the algorithms are applicable to any spherical volume conductor problem involving axial symmetry. The nodal network utilised was characterised by a variable and nonuniform spacing between the nodes and a pointwise variation of conductivity. An excellent accuracy was demonstrated when the numerical solutions were compared with the analytical solutions for several simplified test cases. When simulating the more realistic physiological configurations the model demonstrated a reasonably good agreement with the experimental data obtained from the literature.
