  • Title: Parallel computing with graphics processing units for high-speed Monte Carlo simulation of photon migration.
    Author: Alerstam E, Svensson T, Andersson-Engels S.
    Journal: J Biomed Opt; 2008; 13(6):060504. PubMed ID: 19123645.
    Abstract:
    General-purpose computing on graphics processing units (GPGPU) is shown to dramatically increase the speed of Monte Carlo simulations of photon migration. In a standard simulation of time-resolved photon migration in a semi-infinite geometry, the proposed methodology executed on a low-cost graphics processing unit (GPU) is a factor 1000 faster than simulation performed on a single standard processor. In addition, we address important technical aspects of GPU-based simulations of photon migration. The technique is expected to become a standard method in Monte Carlo simulations of photon migration.
