Abstract

A new noninvasive method for continuously monitoring the blood oxygenation status, especially in the brain of newborn infants is proposed. This approach is based on measurements of the frequency dependent phase shift and demodulation of intensity modulated near infrared light which is transmitted through the skull. The influence of boundary conditions and the skull on the measurements was investigated analytically and with Monte Carlo simulations.
