Abstract

In the current report we present further developments of a unified Monte Carlo-based computational model and explore hyperspectral modelling of light interaction with volumetrically inhomogeneous scattering tissue-like media. The developed framework utilizes voxelized representation of the medium and considers spatial/volumetric variations in both structural e.g. surface roughness and wavelength-dependant optical properties. We present the detailed description of algorithms for modelling of light-medium interactions and schemes used for voxel-to-voxel photon packet transitions. The results of calculation of diffuse reflectance and Bidirectional Scattering-Surface Reflectance Distribution Function (BSSRDF) are presented. The results of simulations are compared with exact analytical solutions, phantom studies and measurements obtained by a low-cost experimental system developed in house for acquiring shape and subsurface scattering properties of objects by means of projection of temporal sequences of binary patterns. The computational solution is accelerated by the graphics processing units (GPUs) and compatible with most standard graphics/ and computer tomography file formats.
