Monte Carlo calculations were used to simulate the propagation of visible and near-infrared light through homogenous tissue in order to quantitate the potential spatial resolution performance for transillumination imaging. Specifically, the relative effectiveness of coaxial collimation and time of flight (TOF) detection for improving spatial resolution was investigated. The results demonstrate that significant improvements in spatial resolution can be achieved through these techniques, with TOF methods offering superior performance for a given level of detected signal intensity.
采用蒙特卡罗计算方法模拟可见光和近红外光在均匀组织中的传播，以定量评估透照成像的潜在空间分辨率性能。具体而言，研究了同轴准直和飞行时间（TOF）检测在提高空间分辨率方面的相对有效性。结果表明，通过这些技术可显著提高空间分辨率，在给定的检测信号强度水平下，TOF方法具有更优的性能。
