Assessing the fractional contributions of static, slow and fast dynamic scatterer components to the flow index derived by continuous wave diffuse correlation spectroscopy
Continuous wave diffuse correlation spectroscopy (cw-DCS) is a noninvasive optical technique to monitor the tissues blood flow changes. This technique measures the tissue blood flow index (BFI) by evaluating the decay rate of the autocorrelation function. The derived BFI is proportional to mean squared displacements of the red blood cells considered as the fast-dynamic scatterer component of…
