A new matrix equation-based theoretical computation method for detection of subsurface defects by thermal-wave tomographic imaging is presented. The numerical calculations of the inverse problem were carried out using the Born approximation, however, the theoretical technique is capable of handling the general tomographic inverse case without recourse to the Born approximation.
