    Optical approaches for neurocritical care: Toward non-invasive recording of cerebral physiology in acute brain injury by Austen T. Lefebvre, Nicole E. Steiner, Carissa L. Rodriguez, Joseph P. Angelo, Eyal Bar-Kochba, Rohan Mathur, Marek Mirski, David W. Blodgett

    Published 2025-01-01
    “…Current established approaches for monitoring cerebral physiology include the neurologic physical examination, traditional brain imaging such as computed tomography (CT) and magnetic resonance imaging (MRI), electroencephalography (EEG), and bedside modalities such as invasive parenchymal probes and transcranial doppler ultrasound. Diffuse optical spectroscopy (DOS), diffuse correlation spectroscopy (DCS), and optical coherence tomography (OCT) are non-invasive optical techniques that have shown promise in measuring clinically relevant changes in cerebral physiology. …”
