Abstract

Measuring blood flow on the head is an indirect yet crucial way to access or quantify brain activity non-invasively, useful for diagnosing traumatic brain injuries by looking at the changes of blood flow. However, measuring the cerebral blood flow (CBF) remains challenging, principally due to the ability to reach and collect signal from the brain. In this talk, I will present our efforts in building an affordable, compact, and portable laser device for real-time Cerebral Blood Flow (CBF) monitoring. Our technique draws upon the speckle visibility spectroscopy technique, using the spatial ensemble of the speckle field to evaluate blood flow dynamics.
