Abstract :
The problem of the image reconstruction of the multi component structure based on indirect boundary observations is considered. The image of the distribution of desired characteristics is described inside the plane domain by some two-dimensional function. A new measurement scheme for the electric tomography is proposed. The mathematical modelling of this measurement scheme leads to the linear method of the image reconstruction, based on the inversion of the classic Radon transformation. The stable algorithm for proposed method is constructed, realized as software for MATLAB system and demonstrated with numerical experiments on simulated examples.
