Abstract

This paper is devoted to the development and testing of accelerated-time calculation for the spatially resolved reflectance in multiple layer turbid medium that facilitates the use of Monte Carlo simulation (MC) in medical physics applications. To mitigate the inconveniences associated to long execution times, the MC code has been speeded up by using efficient computational hybrid technique computing on graphics processing units (GPU). This method effectively reduces the simulation time by a factor of 8 compared to the stand-alone GPU-based MC code.
