Abstract

A Monte Carlo model of light transport in tissue is presented and used to calculate fluence rates within beef liver. The optical coefficients of beef liver used in these calculations have been determined experimentally on both fresh and laser coagulated tissue samples. Coagulation was found to increase the scattering, but left the absorption little changed. Using these measured optical coefficients, the model showed that the light distribution in the tissue was changed significantly following coagulation. The fluence rates in the coagulated tissue were found to be more diffuse than in the fresh tissue.
