A numerical method for an inverse problem for an elliptic equation with the running source at multiple positions is presented. The so-called "approximate global convergence" property of this method is proved for the discrete case. The performance of the algorithm is verified on experimental data for Diffusion Optical Tomography. Direct applications are in near-infrared laser imaging technology for stroke detection in brains of small animals.
