摘要
本文首次用MonteCarlo方法研究了超声调制生物介质中散射光子的时间自相关性质 ,讨论了超声参数、介质的散射系数和吸收系数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了一种新参考。
In this paper,the temporal auto-correlation properties of scattering photons in ultrasound-modulated bio-media were studied by using Monte Carlo method.The effects of ultrasound parameter,scattering and absorption coefficients on the auto-correlation function were discussed.The ultrasound-modualted auto-correlation functions of normal and abnormal bio-tissues have great difference,which can be used to distinguish normal and abnormal bio-tissues.
