摘要
提出了一种用漫射光自相关方法无损测量组织微循环血流速度的模型 ,理论分析了散射粒子的布朗运动和微循环血流对漫射光自相关函数的影响。理论计算和蒙特卡罗 (MonteCarlo)法模拟结果表明 ,随着微循环血流均方速率的增大 。
In this paper, a model was put up to non invasively measure capillary blood flow using diffusion light auto correlation. The influences of the Brownian motion of scatterers and the capillary blood flow on the auto correlation of diffusion light were theoretically analyzed. The theoretical and Monte Carlo simulation results show that the characteristic correlation time exponentially decays as the mean square velocity of capillary blood flow increases.
