EMT has found increasing applications in industrial processes and biomedical applications, such as imaging molten steel fl ow and detecting brain oedema. Further developments of the technique would benefit from advances in fast forward and inverse solvers, low cost yet high performance systems and new emerging application areas such as in landmine detection, food inspection and security applications.
