Determination of the optical properties of tissue by spatially resolved transmission measurements and Monte Carlo simulations

摘要

The spatially resolved transmission through porcine liver is measured with a CCD-Camera. A solution of the diffusion equation is derived to investigate whether the optical coefficients can be deduced from this experimental geometry. The inverse problem is solved with a nonlinear regression program using Monte Carlo simulations as solutions of the forward problem. The experiment is tested with latex-spheres, which are described by Mie-Theory.
