摘要
介绍了用于大脑血流量检测的近红外光谱术的基本原理和实验体系，该系统可完成对近红外光学信号的实时采集、处理和显示等功能．在血模型实验结果基础上。
Cerebral Blood Flow (CBF) is one of the main parameters that reveal the brain function. In this paper, fundamentals for the measurement of CBF with near infrared spectroscopy (NIRS) were introduced. Results of relative changes of blood flow in a brain model were measured by a dual wavelength NIRS system that has specifications of real time sampling, data processing and displaying. An in vivo measurement of relative changes of blood flow in frontal cortex was reported.
