| 摘 要： | 本文首次用Monte Carlo方法研究了超声调制生物介质中漫射光子的时间自相关性质,讨论了超声参量、运动参量和散射参量对自相关函数的影响.正常生物组织和病变生物组织的自相关函数有明显的差别,超声调制自相关函数为光学医学诊断提供一种新参考.

| Abstract: | In this paper,the temporal auto correlation properties of diffusion photons in ultrasound modulated bio media were studied by using Monte Carlo method.The effects of ultrasound,scattering and dynamic parameters on the auto correlation function were discussed.The ultrasound modulated auto correlation functions of normal and abnormal bio tissues have great difference,which can be used to distinguish normal and abnormal bio tissues. |

| Keywords: | Diffusion Auto correlation Ultrasound modulation Monte Carlo |
