Monte Carlo Subsurface Scattering
Subsurface scattering is a technique that has been of great interest to me for some time now. As a 3D lighting artist, the technique has played a huge part in the quality of my renders. My goal with this project was to gain a deeper understanding of the technique so that I may use it in a more intelligent and efficient manner within my art. Figure 1: Example of subsurface scattered light; left ...
متن کاملDosimetry, scattering theory, and Monte Carlo simulation
The purpose of this paper is to provide an introduction to the physics of scattering theory, to define the dosimetric concept of linear energy transfer in terms of scattering theory, and to provide an introduction to the concepts underlying Monte Carlo simulations.
متن کاملScattering Tomography by Monte Carlo Voting
In this paper, we propose a new tomography method called Monte Carlo Voting to visualize the crosssectional surfaces of scattering media. Since the incident light repeats a collision with small particles in scattering media, there are many light paths. To trace them, we use the Monte Carlo ray tracing algorithm and compute the attenuation ratio that represents the likelihood of hidden objects f...
متن کاملStudy of the Compton scattering effect of soft tissue in PET imaging by Monte Carlo method
Introduction:In PET imaging, one or both of two annihilation photons may change the direction before reaching the detector due to Compton scattering interaction in body. .Methods:This article, a Monte Carlo simulation study, examined the effect of soft tissue on this error.In this work, the PET BiographTM 6 scanner, a simple geometry of soft tissue -including a sphere of soft tissue in center ...
متن کاملSea Surfaces Scattering by Multi-Order Small-Slope Approximation: a Monte-Carlo and Analytical Comparison
L-band electromagnetic scattering from two-dimensional random rough sea surfaces are calculated by first- and second-order Small-Slope Approximation (SSA1, 2) methods. Both analytical and numerical computations are utilized to calculate incoherent normalized radar cross-section (NRCS) in mono- and bi-static cases. For evaluating inverse Fourier transform, inverse fast Fourier transform (IFFT) i...
