In Vivo Near-Infrared Spectroscopy
Annual Review of Biomedical Engineering, 2000▪ Abstract Interrogation of tissue with light offers the potential for noninvasive chemical measurement, and penetration with near-infrared wavelengths (750–1000 nm) is greater than with visible light. Specific absorption by clinically relevant compounds such as oxy- and deoxyhemoglobin and the intracellular respiratory enzyme cytochrome oxidase ...

Interpretive Spectroscopy for Near Infrared
Applied Spectroscopy Reviews, 1996ABSTRACT Qualitative and quantitative near infrared spectroscopic (NIRS) methods require the application of multivariate calibration algorithms to model NIR spectral response to chemical or physical properties of a calibration sample set. The identification of unique wavelength regions where changes in the response of the near infrared spectrometer are

A Role for Near Infrared Spectroscopy in Psychiatry?
1997Present implementations of near infrared spectroscopy permit the detection of signals related to neuronal activity non-invasively through the intact skull (for review see: Chance, 1991). Due to the limited penetration of photons in soft tissue that is in the range of a few centimeters (Chance et al., 1993), the NIRS field of view is restricted to the ...

Some of the concepts that make a near infrared spectrum understandable are reviewed. The origin of vibrational anharmonicity which determines the occurrence and the spectral properties (frequency, intensity) is discussed. The importance of the effects of the resonances which increase with increasing excitation are mentioned. Some of the characteristics

In the near-infrared region the absorption process is associated with the overtone and combination bands of vibrational transitions. This region can be studied with the same equipment that is used for electronic spectra, apart from changing from photocell to photoconductive detectors above 1 µ.

Nowadays, various newly developed intracoronary imaging techniques have provided unique information on the coronary plaque and are widely used either for clinical decision-making or for research purposes (Table 9.1). However, there is still unmet need for the characterization of atheromatous plaque, especially for in vivo measurement of lipid burden ...

The discovery of near-infrared energy is ascribed to Herschel in the nineteenth century; the first industrial application however began in the 1950s. Initially near infrared spectroscopy (NIRS) was used only as an add-on unit to other optical devices, that used other wavelengths such as ultraviolet (UV), visible (Vis), or mid-infrared (MIR ...
