Abstract
Monitoring retinal vessel flow properties may aid the screening and the treatment of eye pathologies. We propose to extend the full range ability of the BM-mode scanning technique to high flow structures. The major difference of the proposed method resides in the utilization of a parabolic phase modulation in the reference arm along the B-scan direction. This enables to suppress artifacts generated by the mirror image removal of large velocity structures. We imaged the retina using 1ìm spectral-domain optical coherence tomography and show that this technique enables to have phase-resolved Doppler image where artifacts provoked by high flow vessels are removed. This improvement may help retinal blood flow imaging.
