Abstract:Optical methods are well-suited for non-invasive bedside brain imaging: near-infrared spectroscopy (NIRS) for measuring brain oxygenation and diffuse correlation spectroscopy (DCS) for measuring cerebral blood flow. However, data obtained with those optical techniques are prone to signal contamination from extracerebral tissue. This study aimed to evaluate extracerebral signal contamination in trNIRS/multidistance DCS data acquired during transient hypotension and assess suitable means of separating scalp and … Show more
