摘要
功能性近红外脑成像(functional near-infrared spectroscopy,fNIRS)技术能够有效测量大脑血红蛋白的浓度变化,是一种新型的、无损的检测技术。研发出一种高性能的可穿戴fNIRS系统对于临床诊断和日常生活监测具有重要意义。对比了不同fNIRS系统中的各个组成部分,首先分析比较了系统中光源和光电探测器的选择以及排布方式,其次比较了数据采集、数据预处理和数据分析的方法,最后讨论了提高系统时间分辨率、空间分辨率以及便携性的改进方法。本文可为读者设计一种高性能的fNIRS系统提供指导。
Functional near-infrared spectroscopy(fNIRS)is a new and nondestructive detection technology that can effectively measure changes in cerebral hemoglobin concentration.The development of a high-performance wearable fNIRS system is of great significance for clinical diagnosis and daily life monitoring.This paper compares the components of different fNIRS systems.Firstly,the selection and arrangement of light source and photodetector in the system are analyzed and compared.Secondly,the methods of data acquisition,data preprocessing and data analysis are compared.Finally,the methods of improving the temporal resolution,spatial resolution and portability of the system are discussed.This article provides guidance for the reader in designing a high-performance fNIRS system.
