摘要

文章基于蒙特卡洛方法开发了一种改进的光子在散射生物组织中传播的模拟模型,该模型可以全面考虑光辐射在 BT 传播过程中发生的所有主要光学过程。在所开发统计模型的基础上,对光子在皮肤及其各层中的传播过程进行了模拟建模,从而确定了各皮肤层的散射和透射特性,模型参数考虑了可见光和近红外范围辐射的入射角度以及皮肤层的厚度。此外,模拟还可以确定散射光子的相对强度,这取决于定位。

Simulation of photon migration process in the biological environment
The article developed an improved simulation model of the propagation of photons in scattering biotissue based on the Monte Carlo method, which allows comprehensive consideration of all the main optical processes that occur during the propagation of optical radiation through BT. On the basis of the developed statistical model, simulation modeling of photon propagation processes in the skin and its separate layers was carried out, which allowed to establish the scattering and transmission characteristics for each of the skin layers with model parameters taking into account the angles of incidence of radiation in the visible and near-IR ranges, the thickness of the skin layers. Also, the simulation made it possible to determine the relative intensity of scattered photons depending on localization.
