Abstract

Near-infrared spectroscopy (NIRS) is an optical technique that can measure brain tissue oxygenation and haemodynamics in real time and at the patient bedside allowing medical doctors to access important physiological information. In particular, time-domain NIRS (or TD-NIRS) is the most advanced NIRS technique, collecting the biggest amount of information, increasing the accuracy of the measurements and enabling to extract detailed information of the absolute optical properties of the tissues. All these optical information allows to extract detailed physiological information about the brain, and also get some insights into to the tissue’s anatomy. After presenting the basics of TDNIRS, typical applications of TD-NIRS in a clinical context will be presented.
