Capillary red blood cell velocimetry by phase-resolved optical coherence tomography September 27, 2017 | Uncategorized | Boston University, Harvard University, Massachusetts General Hospital We present a phase-resolved optical coherence tomography (OCT) method to extend Doppler OCT for the accurate measurement of the red blood cell (RBC) velocity in cerebral capillaries.

Optical coherence tomography of arteriolar diameter and capillary perfusion during spreading depolarizations | Neurology | Massachusetts General Hospital Spreading depolarization (SD) is associated with profound oligemia and reduced oxygen availability in the mouse cortex during the depolarization phase. Coincident pial arteriolar constriction has been implicated as the primary mechanism for the oligemia. However, where in the vascular bed the hemodynamic response starts has been unclear.

Scalable mapping of myelin and neuron density in the human brain with micrometer resolution January 12, 2022 | Neurology | Boston University, Massachusetts General Hospital Optical coherence tomography (OCT) is an emerging 3D imaging technique that allows quantification of intrinsic optical properties such as scattering coefficient and back-scattering coefficient, and has proved useful in distinguishing delicate microstructures in the human brain.
