The Model of Optical Radiation Propagation in Tissue


The paper shows the relevance of developing the model of optical radiation propagation in tissue that will further implementatation of calculation engineering methods of optical radiation intensity distribution in tissues for surgical intervention or therapeutic effect. We propose the so called “three pulse” model of optical radiation propagation in tissue and method based on it. To calculate the coefficients of the model basic expression, we develop the three equation system. These equations describe the boundary conditions of optical radiation propagation in tissue. By using the Monte-Carlo simulation method and proposed engineering method we compare results of optical propagation in tissue for identical tissue optical parameters. These results correlate with the mean square modelling error (within 15 %) for other analytical models. The proposed calculation engineering method for optical radiation intensity distribution in tissue may be alternative for Monte-Carlo simulation method with considerable calculation simplification and calculating time reduction.
