Computer-aided generation of reference data for 3-D evaluation of light - tissue interaction

摘要

This paper is dedicated to computer-aided modeling of attributes of human tissues which are exposed to determined light action for measurement purposes. The transmission mode of light-tissue interaction is assumed. By use of either cross-section or longitudinal section of a multilayered tissue slab with planes perpendicular to the direction of light action, respectively, two-dimensional representation of three-dimensional structure is considered. In such an approach, effects resulting from light transmission can be studied for the light intensity vector in the rectangular coordinates. The proposed structure of a specialized algorithm makes it possible to create free variants of reference standards, including changes in a number of layers and their biophysical composition. Exemplary results of calculations for the tissue slab transilluminated in x-y coordinates are presented, at red light to be acting. The major aim of further works is to carry out an "atlas" of variants modeling optical properties of living tissues which one could be a comprehensive source of standard data for virtual and real measurements based on utilization of light transmission through an object to be investigated.
