Susceptibility tensor to absorption quantumwise

Our results showed that, when the refractive index of several bio-tissues which had the same effective attenuation coefficient were the same, the depth resolved internal fluence would be the same otherwise, the depth resolved internal fluence would be not the same. Also, the influence of bio-tissue refractive index on the distribution of light fluence was discussed in detail.

In order to assess the validity of knowledge above, depth resolved internal fluence of several semi-infinite biological tissues which have the same effective attenuation coefficient were simulated with wide collimated beam in the paper by using Monte Carlo method in different condition.

Thus, a misinterpret of analytical solution would be made: while the effective attenuation coefficient of several semi-infinite bio-tissues were the same, the distribution of light fluence in the tissues would be the same.

A simple analytical solution could be obtained easily from the diffusion equation after a series of approximations. The concepts and equations of diffusion are developed on an elementary level, with emphasis on atmospheric applications.Р”Р„ discussion on validity of the diffusion theory by Monte Carlo methodР”Вiffusion theory was widely used as a basis of the experiments and methods in determining the optical properties of biological tissues. A multilayer diffusion model, designed to permit concentration and dosage calculations downwind of toxic clouds from rocket vehicles, is described. [emphasis on atmospheric applicationsР”Р„n introductory treatment of the fundamentals of diffusion theory is presented, starting with molecular diffusion and leading up to the statistical methods of turbulent diffusion. Some basic mathematical methods of diffusion theory.
