Abstract
We present a model of the forward problem for diffuse photon density waves in
turbid medium using a diffraction tomographic problem formulation. We consider a
spatially-varying inhomogeneous structure whose absorption properties satisfy
the Born approximation and whose scattering properties are identical to the
homogeneous turbid media in which it is imbedded. The two-dimensional Fourier
transform of the scattered field, measured in a plane, is shown to be related to
the three-dimensional Fourier transform of the object evaluated on a surface
which in many cases is approximately a plane.
