2025年1月27日 · Functional near-infrared spectroscopy (fNIRS) is an increasingly popular neuroimaging technique that measures cortical hemodynamic activity in a non-invasive and portable...

2019年3月1日 · Following a period of blood flow occlusion, the near-infrared spectroscopy (NIRS)-derived reperfusion slope of the oxygen saturation signal (StO2) is a measure of microvascular responsiveness that has been shown to be positively correlated with flow-mediated dilation (FMD) assessment of conduit artery function in the lower limb vasculature.

Abstract: In this study, we tried to discriminate the direction of arm force from hemoglobin concentration changes measured by near-infrared spectroscopy (NIRS). A self-organizing map (SOM) was used to classify the force direction information obtained from the NIRS signals.

2021年3月1日 · Near-infrared spectroscopy (NIRS) is a method for non-invasive monitoring of somatic and cerebral oxygenation and hemodynamics. It reflects the balance between tissue oxygen supply and demand.

Functional Near-Infrared Spectroscopy (fNIRS) aims to recover changes in tissue optical parameters relating to tissue hemodynamics, to infer functional information in biological tissue. A widely-used application of fNIRS relies on continuous wave (CW) methodology that utilizes multiple distance measurements on human head for study of brain health.

2024年10月29日 · 近红外光谱（nirs）是一种光谱分析技术技术，该技术通过光密度的变化，计算局部组织（如肌肉或大脑）中氧合血红蛋白 （o2hb）和脱氧血红蛋白 （hhb）的相对浓度变化。

2022年2月22日 · The primary purpose of cerebral oxygenation monitoring by near-infrared spectroscopy (NIRS) is to allow for timely interventions to prevent cerebral hypoxia and subsequent brain injury, 1,2,3...

2025年3月28日 · Near-Infrared Spectroscopy (NIRS) is a non-invasive technique that measures variations in the oxygenation of brain tissue, specifically the transition between oxygenated hemoglobin [oxy-Hb] and deoxygenated hemoglobin [deoxy-Hb], which results from neuronal activity (Functional NIRS [fNIRS]).

2022年1月20日 · Cerebral oximetry using near-infrared spectroscopy (NIRS) is used for monitoring cerebral oxygen saturation during cardiac surgery and is correlated with clinical outcomes. Our goal was to explore cerebral and somatic NIRS in liver resections as a predictor of post-operative complications.

2013年1月1日 · Two wearable NIRS devices (PortaMon, Artinis Medical Systems) were used to compare muscle tissue oxygen saturation (TSI%) and total haemoglobin (tHb) changes in the quadriceps muscle group (vastus lateralis) and a muscle of …
