Abstract
A time resolved method based on near infrared spectroscopy for monitoring of changes in tissue absorption and concentration of the exogenoeus chromophore concentration is presented. We constructed a setup which can be used to measure changes in oxygenation of the brain tissue by monitoring of diffuse reflectance at two wavelengths. Currently, the instrument has been modified in such a way that simultaneous measurements of diffuse reflectance and fluorescence can be carried out. We present results of measurement of diffuse reflectance and fluorescence during injection of an optical contrast agent in healthy volunteer.
