Abstract: In this work a
generalized iterative back-projection algorithm for the 2-D reconstruction of resistivity data is proposed. The need for such an
algorithm derives from the analysis of the limitations of the existing
approximate algorithms. Further, it can reconstruct data from any array as well
as from unconventional electrode arrangements. The merits and limitations of
the algorithm are discussed and examples of its performance with synthetic data
are given. Extensive tests of the algorithm with real data obtained from
archaeological sites are presented as well. Despite its inherent limitations
the algorithm proved to be reliable and noise insensitive and produced good
