Abstract

We introduce a new software correlator approach for continuous high-speed (up to 100 Hz) monitoring of blood flow dynamics with Diffuse Correlation Spectroscopy. The functionality of the high-speed software correlator is demonstrated with measurements of baseline blood flow dynamics. The utility of high-data-rate blood flow monitoring is demonstrated with measurements of cerebral autoregulation dynamics.
