摘要
人体的皮肤颜色根据种族不同存在着很大差异,同一种族随着居住地域不同,肤色也各不相同。首先根据皮肤结构与光学特性建立新生儿七层皮肤模型,然后使用蒙特卡罗方法通过改变表皮黑色素体积分数来模拟光在不同肤色条件下的传播情况。模拟结果表明,新生儿肤色差异对光在皮肤内的传播特性有较大影响,且会对黄疸无创检测的关键波长造成干扰,从而影响新生儿黄疸无创检测的准确性。
The skin colors of humans vary considerably based on which race they belong to and where they live.First,a seven layer neonatal skin model was established herein according to the skin structure and optical characteristics.Subsequently,the Monte Carlo method was used to simulate the propagation of light under different skin color conditions by varying the volume fraction of epidermal melanin.Simulation results show that the difference in the neonatal skin color greatly affects the propagation characteristics of light through the skin.This difference interferes with the key wavelength of noninvasive detection of neonatal jaundice,thus affecting the accuracy of such detection.
