Abstract
The regularities of movement of the Photon Density Normalized Maximum (PDNM) in highly scattering media such as biological tissues are described. An improved model of the optical properties of turbid media based on the diffusion approximation to the Radiative Transfer Equation (RTE) is used for identifying regularities of PDNM movement. Numerical simulations confirmed that in homogeneous cylindrical objects PDNM always moves to the geometric centre of the object. In the case of single absorbing inhomogeneities PDNM moves towards the point which is symmetrical to the geometric centre of it with respect to the center of the object. In the presence of a single scattering inhomogeneity PDNM moves towards its geometric centre.
