Abstract

Over the past decades, several techniques have been developed to measure cerebral hemodynamic parameters such as red blood cell velocity, flux and hematocrit using optical coherence tomography (OCT). Despite these advancements, two photon microscopy (TPM) remains the gold standard for functional cerebral hemodynamic imaging, though localized line-scan or bolus tracking. Here we developed an optical platform enabling concurrent imaging with OCT and TPM and perform co-localized and simultaneous velocimetric measurements with both modalities, with the aim of validating OCT velocimetric methods.
