Abstract
In this work we compare the Born and Rytov approximations for frequency-domain diffusing wave tomography. We confirm that the Rytov approximation gives a more accurate reconstruction of the absorptive properties. In addition, the natural separation of amplitude and phase within the Rytov approximation presents the possibility for image reconstruction algorithms which use either the phase shift or the amplitude decay of the diffusive waves. We demonstrate this effect, and apply these algorithms to simultaneously reconstruct the scattering and absorption properties of heterogeneous turbid media.
