Paper Abstract

We look at the transillumination imaging of relatively thick tissues, for which the diffusion approximation is valid. We solve the direct problem for a sphere of arbitrary radius, scattering and absorption, imbedded in a scattering and absorbing slab. We consider several source configurations: wide beam, point and dipole sources, either cw or modulated. We discuss the results, particularly the resolution threshold, i.e., the sphere radius above which the inverse problem can be solved accurately.
