Functional Interferometric Diffusing Wave Spectroscopy
July 20, 2021 | Terry Sharrer
To image cerebral blood flow, University of California-Davis scientists “describe functional interferometric diffusing wave spectroscopy (fiDWS), which introduces and collects near-infrared light via the scalp, using inexpensive detector arrays to rapidly monitor coherent light fluctuations that encode brain blood flow index (BFI), a surrogate for CBF. Compared to other functional optical approaches, fiDWS measures BFI faster and deeper while also providing continuous wave absorption signals.” MORE
