After illustrating the techniques in time-harmonic acoustic problems with different boundary conditions and in electrical impedance tomography problems with continuous Neumann conditions, we extend the hybrid method for a realistic model in tomography where the boundary conditions are given at a discrete set of electrodes.engjournal articlehttps//doi.org/10.1155/2013/816134http://www.hindawi.com/journals/aaa/2013/816134/open access616Electrical-impedance tomographyInverse scattering problemsLevel set methodsShape-reconstructionAcoustic scatteringConductivityObstacleIdentificationApproximationOptimizationFísica (Física)22 Física
