图形处理单元（GPGPU）上的通用计算显着提高光子迁移的蒙特卡罗模拟的速度。在半无限几何结构中时间分辨光子迁移的标准模拟中，在低成本图形处理单元（GPU）上执行的所提出的方法比在单个标准处理器上执行的模拟快1000倍。此外，我们解决了基于GPU的光子迁移模拟的重要技术问题。该技术有望成为光子迁移蒙特卡罗模拟的标准方法。(C)2008年，由光学仪器工程师协会（Society of Photo-Optical Instrumentation Engineers）主办。[DOI 10.1117/1.3041496]
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.
