Abstract

In this paper we examine the performance of a number of linear techniques for reconstructing the 3-D distribution of absorption coefficient within a highly scattering medium using the diffuse photon density wave (DPDW) approximation. The simulation consists of a coplanar array of sources and detectors at the boundary of an infinite slab medium. The primary difficulty in the linear reconstruction of the 3D volume from a 2D array of measurement is that the forward matrix is both underdetermined and ill-conditioned.
