Abstract

A linear forward model of light propagation in turbid media for three dimensional (3D) optical tomography is formed based on the analytical cumulant solution of the Boltzmann radiative transfer equation., for time resolved, CW, and frequency-domain measurements in parallel slab geometry. This forward model is more accurate than the forward model based on the diffusive approximation. An inverse algorithm is developed, based on a fast 3D hybrid-dual-Fourier tomographic approach using multiple detectors and multiple sources in parallel geometry, which incorporates the cumulant radiative transfer model. The inverse algorithm runs fast that can produce a 3D image of a turbid medium with more than 20,000 voxels in 1-2 minutes using a PC computer. A 3D image is presented using simulated data.
