MONTE CARLO SIMULATION OF LIGHT SCATTERING IN HUMAN SKIN LAYERS BY SPATIAL PHOTOMETRY METHODS

The ability to register and analyze the spatial distribution of light scattered within full solid angle is basis for development improvement information-measuring systems software hardware complexes problems optical biomedical diagnostics. greatest contribution scattering at non-invasive methods research are made by layers human skin, affecting depth probing resolution diagnostic systems. significant individual variability properties biological tissues does not allow practically (clinically) assessing their effect on characteristics; therefore, use modeling radiation propagation in media measuring tools functioning context makes it possible provide such a prognostic analysis. goal this work comparative evaluation results skin Monte Carlo simulation using photometer with ellipsoidal reflectors goniophotometer.
 dermis epidermis wavelength 632.8 nm photometry "BT_Mod" software, as well coordinates, direction, statistical weight photons, allows ray-tracing presented work.
 As result modeling, graphs dependence coefficients (transmission T, diffuse reflection Rd, absorption A) studied various thicknesses value anisotropy factor were obtained, photometric images second focal plane when receiving spot reflected transmitted light. Diagrams averaged indicatrix three obtained set biophysically values factor, based which integral photons was analyzed. A quantitative assessment illuminance level carried out according zone analysis principles reflectors. resulting external middle rings light.
 make (epidermis dermis) angle, can be used dosimetry medical imaging diagnostic, endoscopic, therapeutic biophotonics.
