Comparison of phase-resolved Doppler optical coherence tomography and optical coherence tomography angiography for measuring retinal blood vessels sizeJournal of Computational Vision and Imaging Systems

Abstract:

Abstract The goal of this study was to compare two OCT-based methods for measuring 
retinal blood vessels size: Phase-resolved Doppler OCT (DOCT) and OCT angiography 
(OCTA). The study was conducted in rats (n= 6) using a SD-OCT system operating at 1060 
nm with 92 kHz image acquisition rate. Arteries and veins were separated by the phase 
polarity. Results from this study showed that the venal diameters are significantly larger than 
the arterial diameters, and there is no significant difference in the vessel diameters 
measured by both methods.
