功能性近红外技术是一种新型无损检测人脑功能性活动的探测技术,该技术监测到的脑功能信号易受到生理活动和人的相对运动的干扰,分别称为生理干扰和运动伪迹,这些干扰的存在严重影响信号质量,因此需要开发消除生理干扰和运动伪迹的信号处理方法。介绍了目前功能性近红外信号的主要干扰源、相应的生理干扰与运动伪迹的去除方法,分析了当前功能性近红外技术存在的问题和可能的发展方向,并重点讨论了功能性核磁共振技术与功能性近红外技术的优劣。最后总结了功能性近红外数据处理方面的发展前景。
Functional near-infrared technology is a new non-destructive detection of human brain functional activity detection technology, the technology to monitor brain signals susceptible to physical activity and human relative motion interference, respectively, known as physiological interference and motion artifacts, The existence of these disturbances severely affects the signal quality, so there is a need to develop signal processing methods that eliminate physiological disturbances and motion artifacts. The main interference sources, corresponding physiological disturbances and motion artifact removal methods of the current near-infrared signal are introduced. The existing problems and possible future directions of the present near-infrared technology are analyzed. The functional magnetic resonance The advantages and disadvantages of technology and functional near infrared technology. Finally, the development of functional near-infrared data processing is summarized.
