Conceptual engineering design and optimization of laser-based imaging techniques and optical diagnostic systems used in the field of biomedical optics requires a clear understanding of the light-tissue interaction and peculiarities of localization of the detected optical radiation within the medium. The description of photon migration within the turbid tissue-like media is based on the concept of radiative transfer that forms a basis of Monte Carlo (MC) modelling. An opportunity of direct simulation of influence of structural variations of biological tissues on the probing light makes Monte Carlo a primary tool for biomedical optics and optical engineering. Due to the diversity of optical modalities utilizing different properties of light and mechanisms of light-tissue interactions a new Monte Carlo code is typically required to be developed for the particular diagnostic application. In current Lecture introducing an object oriented concept of Monte Carlo modelling and utilizing modern web applications we present the generalized and unified computational tool suitable for the major applications in Biophotonics and Biomedical Optics.
