Clinical application of functional near-infrared spectroscopy for burn assessment

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
Significance: Early assessment of local tissue oxygen saturation is essential for clinicians to determine the burn wound severity.Background: We assessed the burn extent and depth in the skin of the extremities using a custom-built 36-channel functional ...

Microfluidic Cuvette for Near-Infrared Spectroscopy

open access: yesProceedings
We intend to develop an in situ near-infrared spectroscopic solution for monitoring the nutrient composition (e.g., lactate concentration) in microfluidic channels of organ-on-chip devices.

Near-infrared spectroscopy in psychiatry

open access: yesEquilibrium Research, 2010
Near-infrared spectroscopy (NIRS) is a functional neuroimaging technique that has been increasingly employed in psychology and psychiatry. Because NIRS can detect only cerebral cortex reactivities with low spatial resolution and may suffer from contaminating signals from the skin and skull, its data should be interpreted as a global index of cerebral ...

Ultrafast infrared near-field molecular nano-spectroscopy

open access: yesEPJ Web of Conferences, 2013
We demonstrate molecular radiative infrared vibrational free-induction decay on the nano-scale and its control via near-field coupling between the transient molecular polarization and optical antenna properties of the metallic scanning near-field probe ...

A Systematic Comparison of Motion Artifact Correction Techniques for Functional Near-Infrared Spectroscopy

open access: yesFrontiers in Neuroscience, 2012
Near-infrared spectroscopy (NIRS) is susceptible to signal artifacts caused by relative motion between NIRS optical fibers and the scalp. These artifacts can be very damaging to the utility of functional NIRS, particularly in challenging subject groups ...

Infrared fibres in astronomical instrumentation [PDF]

open access: yes, 1995
For several years multi-object spectroscopy systems have been available for carrying out survey work in the visible region, but until very recently there has not been a system for the near infrared region.

Studies of Near Infrared Spectroscopy for P!'edicting Forage Quality of Tropical Grasses [PDF]

open access: yes, 1992
Introduction Near Infrared Reflectance Spectroscopy (NIRS) for forage has been widely and successfully used throughout the world, but the study for tropical grasses is still limited, especially in Asia including Japan and Indonesia.

Relationship between oxygen supply and cerebral blood flow assessed by transcranial Doppler and near-infrared spectroscopy in healthy subjects during breath-holding [PDF]

open access: yes, 2006
Background Breath – holding (BH) is a suitable method for inducing cerebral vasomotor reactivity (VMR). The assessment of VMR is of clinical importance for the early detection of risk conditions and for the follow-up of disabled patients.

Near‐infrared spectroscopy in child and adolescent neurodevelopmental disorders

open access: yesPCN Reports, 2022
Near‐infrared spectroscopy (NIRS) is a noninvasive optical technique that uses the near‐infrared spectrum for functional neuroimaging by measuring oxygenation and hemodynamic changes in the cerebral cortex.

Theoretical investigation of measuring cerebral blood flow in the adult human head using bolus indocyanine green injection and near-infrared spectroscopy [PDF]

open access: yes, 2007
To investigate the accuracy of measuring cerebral blood flow (CBF) using a bolus injection of indocyanine green (ICG) detected by near infrared spectroscopy in adult human heads, simulations were performed using a two layered model, representing the ...
