The technique of computerized image reconstruction of electrical resistance in earth has been newly developed by numerical analysis methods, such as, finite element, finite difference, resistance network, integral equation and these complex solution. In this study, a new sensitivity distribution technique is proposed to improve the reliability of resistivity interpretation, mainly, to improve the subsurface image reconstruction by not only apparent resistivity measurements but also differential electrical measurements, i.e., the extended differential sensitivity distribution methods. Special cases of CC (drillhole DH-1) PP (surface) hole-to-surface, C (hole DH-1) PP (hole DH-2) crosshole, and CC (tunnel TL-1) PP (surface) tunnel-to-surface configurations were discussed.
