Abstract : Over the last years, tissue microcirculatory and regional perfusion and oxygenation have made an important entry into the functional hemodynamic monitoring of critically ill patients (1). Clinical assessment of these parameters has become possible by the introduction of optical spectroscopic technologies such as near-infrared spectroscopy ...

Near infrared spectroscopy is a novel technique still at an early stage in its development. Current technology has been used to measure cerebral haemodynamics and oxygenation at the cotside in sick preterm infants, to observe cerebral oxygenation during birth, and in other situations such as cardiac surgery. At present it is best regarded as a research

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 ...

Near-Infrared Spectroscopy in Pediatric Congenital Heart Disease.
Journal of Cardiothoracic and Vascular Anesthesia, 2020Near-infrared spectroscopy (NIRS) is widely used to monitor tissue oxygenation in the pediatric cardiac surgical population. Clinicians who use NIRS must understand the underlying measurement principles in order to interpret and use this monitoring ...

Understanding Near-Infrared Spectroscopy
Advances in Neonatal Care, 2011Near-infrared spectroscopy (NIRS) is a noninvasive technique that monitors regional tissue oxygenation reflecting perfusion status. Near-infrared spectroscopy has the ability to continuously and simultaneously monitor tissue perfusion in different organ systems at the bedside without interrupting routine care.

Near-infrared spectroscopy is a new technique for noninvasive monitoring of tissue oxygenation and hemodynamics. Until now, it has been used solely for research into the physiopathology of the brain. This technique offers considerable untapped potential for research and clinical applications.

Journal of Near Infrared Spectroscopy, 1998
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.

Functional near-infrared spectroscopy
IEEE Engineering in Medicine and Biology Magazine, 2006The purpose of the this article is to describe an emerging neuroimaging technology, functional near-infrared spectroscopy (fNIRs), which has several attributes that make it possible to conduct neuroimaging studies of the cortex in clinical offices and under more realistic, ecologically valid parameters.
