brain near-infrared spectroscopy (nirs)
near-infrared spectroscopy (nirs) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum. typical applications include medical and physiological diagnostics. nirs can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., ...
متن کاملNear Infrared Spectroscopy (NIRS)
Near infrared spectroscopy (NIRS) is a noninvasive optical technology that relies on the relative transparency of biological tissues to near infrared light (700-900 nm) to determine tissue oxygenation. Oxy and deoxy hemoglobin and cytochrome aa3 possess distinct absorption characteristics in the near infrared spectrum. By monitoring absorption at wavelengths where oxyand deoxyhemoglobin and cyt...

متن کاملUse of near-infrared spectroscopy (NIRS) in cerebral tissue oxygenation monitoring in neonates.
Near-infrared spectroscopy (NIRS) is a technology capable of non-invasive, continuous measuring of regional tissue oxygen saturation (StO2). StO2 represents a state of hemodynamic stability, which is influenced by many factors. Extensive research has been done in the field of measuring StO2 of various organs. The current clinical availability of several NIRS-based devices reflects an important ...
متن کاملNear infrared spectroscopy (NIRS) distinguishes seizure types
Near infrared spectroscopy (NIRS) is a noninvasive method for bedside measurement of cerebral oxygenation (SaO(2)). The purpose of this study was to establish differences in SaO(2)for complex partial seizures (CPS) and rapidly secondarily generalized CPS (RCPS). We studied eight adults with medically refractory epilepsy undergoing evaluation for temporal lobectomy. We continually measured cereb...
