Abstract :
The main purpose of this paper is to investigate some stability issues observed in the surface shape reconstruction algorithm of 3-D irregular breast tumors. The developed algorithm is based on integrating the method of moments (MoM) for the forward solver with the adjoint-field scheme for the computations of appropriate sensitivities derivaties. The results show that the stability of the algorithm relies on the manner in which the adjoint fields are calculated.
