基于Monte Carlo方法的NIRS生理检测研究
Research on NIRS Physiological Detection by Monte Carlo Method
【摘要】 在NIRS生理检测技术的基础上,提出以扫描方式进行NIRS检测的新构想.以Monte Carlo方法展现其成像过程,并首次尝试以Monte Carlo方法对扫描式NIRS检测进行分析,以Visual C++编制程序,建立由组织结构到检测影像的检测模型.对一百万条光线进行追踪,对比分析了不同长度通道的扫描影像,并进行实测,得出该方式下检测影像的分辨率好于传统方式,证实了该方法的独特性.
【Abstract】 Based on NIRS physiological detection technologies,a new idea about scanning-style NIRS detection is put forward,where the NIRS imaging process will be implemented by Monte Carlo method with which the effect of scanning-style NIRS detection is first analyzed.Programmed with Visual C++,the detection model is developed from histology to image detection to trace a million of rays,then a comparative analysis is made for the scanned images of the channels of different lengths in combination with actual detection.A conclusion is thus drawn that the new-style detection has higher resolution than conventional one,thus verifying the distinctiveness of the new method.
