Abstract
Cerebral blood flow monitoring is critical and is carried out routinely in clinical settings. There are noninvasive techniques based on near-infrared diffuse optics that have been developed in the past decades and are being used in clinical research. ICFO-Medical Optics group has developed techniques for continuous noninvasive measurements based on Diffuse Correlation Spectroscopy (DCS). Recently, due to the advancements in DCS technology, measurements with a temporal resolution higher than 25Hz can be done, allowing us to resolve the pulsatile behavior of blood flow due to the cardiac cycle. Fast blood flow measurements can enable new applications for DCS, with new potential bio-markers related to the pulsatile signal. To realize the clinical potential of DCS pulsatility monitoring, a better understanding of the influences on the measurements is needed to estimate pulsatility in a precise manner. In this project, we introduce a pulsatile tissue simulating phantom using a DCS device and analyze and compare the pulsatile signals obtained under different conditions by defining a pulsatility index.
