Bedside Optical Monitoring of Cerebral Blood Flow, Using Penn-designed Device, Shows Promise for Individualized Care in Stroke Patients
The Penn-designed novel optical technique, called diffuse correlation spectroscopy (DCS), uses a noninvasive probe placed on the surface of the head to measure the fluctuations of near-infrared light caused by moving red blood cells in tissue, and has been shown to accurately track cerebral blood flow in underlying brain tissue.
