A multimodal optical imaging platform is used to obtain cerebral perfusion-metabolism mismatch metrics for rapid assessment of acute brain injury, ongoing (real-time) feedback to optimize cardiopulmonary resuscitation to improve neurological outcome, and rapid prognosis of recovery. Light of several wavelengths and types is delivered to the tissue, which is then absorbed and scattered by tissue components such as blood and cellular components. Some of this light scatters back to the surface, where it is captured by a detector. The resulting data are processed to obtain blood flow and oxygenation parameters, as well as tissue scattering. These parameters are then combined to calculate metabolism and flow-metabolism coupling/decoupling metrics, which are used to determine ischemic damage, ongoing need for optimal blood flow and oxygenation, and to predict cerebral recovery in patients with acute brain injury during and immediately after cardiac arrest, stroke, traumatic brain injury, etc.
