“…The developed MC model has been verified by a direct comparison of the results of modeling of CVB and Gaussian beam propagation through the turbid scattering medium. In terms of accuracy of the modelling, we emphasize that early, it has been shown that MC approach is able to imitate the results of actual experiment [55]. The obtained results are also in a good agreement with the results of alternative studies of deep transmission of LG vortex beams through the turbid media in comparison with the Gaussian beam [56].…”

We explore the propagation of the cylindrical vector beams (CVB) in turbid tissue-like scattering medium in comparison with the conventional Gaussian laser beam. The study of propagation of CVB and Gaussian laser beams in the medium is performed utilizing the unified electric field Monte Carlo model. The implemented Monte Carlo model is a part of a generalized on-line computational tool and utilizes parallel computing, executed on the NVIDIA Graphics Processing Units (GPUs) supporting Compute Unified Device Architecture (CUDA). Using extensive computational studies, we demonstrate that after propagation through the turbid tissue-like scattering medium, the degree of fringe contrast for CVB becomes at least twice higher in comparison to the conventional linearly polarized Gaussian beam. The results of simulations agree with the results of experimental studies. Both experimental and theoretical results suggest that there is a high potential of the application of CVB in the diagnosis of biological tissues.

“…The results of comparison are presented in Table 2. The developed MC technique has been also comprehensively validated by comparison with the known exact solution by Milne [32][33][34][35] and with the results of experimental studies of image transfer through the water solution of spherical microparticles of known size and density [36][37][38][39][40] .…”

We present a peer-to-peer realization of the online object oriented Monte Carlo code as a further development of the unified model of photon migration in complex turbid media such as biological tissues. The object oriented programming is used for to generalization of the code for multi-purpose use in various applications of biomedical optics. The peer-topeer network share their GPUs communicate and technique utilizes parallel computing on Graphical Processing Units for acceleration and a web application solution to provide users with the direct access for on-line modeling. We demonstrate that Peer-to-Peer realization could potentially deal with the limitations imposed by the multi-user access to the on-line modeling. Currently the online MC tool is available to the biophotonics community through its website hosted in Australasia: www.biophotonics.ac.nz

Предлагаемый подход имеет некоторые сходства (формирование и распространение в толще исследуемой ткани) с моделированием движения виртуального изотропного источника [9,26,27], но принципиально отличается от него тем, что НМФП -не дополнение к функции источника фотонов, а результат постобработки уже вычисленного многомерного массива данных φ(x, y, z , t).…”

The specific features of photon diffusion of low-coherence pulsed irradiation in phantoms of soft biological tissues (blood-saturated tissues of the brain, breast, etc.) are described. The results of photon migration simulation using the Diffusion Approximation to the Radiation Transfer Equation (RTE) are compared with ones of the Monte Carlo simulations. It has been confirmed that the Photon Density Normalized Maximum (PDNM) moves towards the center of the investigated object in case of relatively uniform and strongly scattering media. In the presence of inhomogeneities, type of the PDNM motion changes drastically. Presence of an absorbing inhomogeneity in the medium directs trajectory of the PDNM motion of towards the point symmetric to the inhomogeneity relative to the geometric center of the investigated object. In case of scattering the PDNM moves toward the direction of the center of the scattering inhomogeneity.
