Abstract
Simulation of tomography reconstruction of several absorbing macro-inhomogeneities in a strongly scattering cylindrical body was carried out not using any prior information on the structure of macro-inhomogeneities. The data of time-domain measurements were simulated using a diffusion equation solving by FEM. For the reconstruction procedure the method based on curvilinear photon average trajectories (PAT) was used. This method allows solving the inverse problem of optical tomography in terms of a set of linear equations with a sparse coefficient matrix. Special methods for sparse matrix processing permit to decrease sufficiently the computing time for image reconstruction. The comparison was carried out for the results of application of the several matrix solvers used in conventional CT (such as MART, NNLS, LSQR, and their combinations) to PAT method. In order to estimate the computing time and the quality of reconstruction, a comparison was carried out between the images restored using PAT method and using multi-iterative program MMTOAST10, which employs FEM solving of the diffusion equation. It was shown that the trajectory method, being much faster, gives the comparable quality of the restored images.
