Methods of Quantitating Cerebral Near Infrared Spectroscopy Data
Non invasive infrared spectroscopy is a well established technique for monitoring changes in the oxygenation status of tissues (1). The technique has in particular been successfully employed to monitor changes in cerebral blood and tissue oxygenation by observing the absorption of haemoglobin and cytochrome aa3 respectively. Because of the highly light scattering nature of the tissues studied, it has normally not been possible to quantitate the observed changes.
