Abstract

Based on a multigrid forward solver of radiative transfer equation for optical imaging, an efficient multilevel simultaneous reconstruction of absorption and scattering coefficient is presented, in which L₁ minimization can be used to localize the unknowns, especially in the presence of sparse unknowns.
