摘要：
In current Monte Carlo (MC) simulations of the light propagation in biological tissues, the sources (S) or detectors (D) are mainly positioned in view of 2-D planes, leading to the rough accuracy, and low efficiency. This paper proposed a 3-D visualization platform with interactive view to determine the S D coordinates as well as the incident direction of source light. Moreover, the proposed system permits implementation of the MC simulation in a flexible voxel spacing, beyond the original voxel of medical images. Validation studies on a realistic 3-D human head model show that the S D pairs can be fast and accurately positioned on the tissue surface with assistance of the visualization platform, indicating its great potential for biomedical optical applications.
