Paper Abstract

In this paper, a 3D dual-mesh imaging reconstruction method is demonstrated, which can reconstruct absorption and scattering coefficients simultaneously. In the dual-mesh scheme, the total number of voxels with unknown absorption and scattering perturbations are maintained on the same order of total measurements by using a fine grid for target region and a coarse grid for background region. Certain row/column normalization has been applied to alleviate the crosstalk between the absorption coefficient and scattering coefficient, and to minimize the depth dependent problem. Experimental results of targets with different absorption and scattering contrasts have shown that accurate reconstruction of both absorption and scattering coefficients can be achieved.
