different types of waves (or physical fields) these methods overcome limitations of classical tomography techniques and
deliver otherwise unavailable, potentially life-saving diagnostic information. Besides medical imaging there has been also
recent interest on coupled-physics inverse methods in oil exploration in particular on the seismo-electric effect.
