Abstract
A motion - corrected en face optical coherence tomography angiography (OCT - A) imaging method is presented in this paper. This method was designed to correct eye motion artifacts in en face OCT - A images automatically using a software. A modified Lissajous scanning pattern, which is compatible with OCT - A, was adopted as the scanning protocol for the optical coherence tomography (OCT) machine to obtain the OCT - A data. The OCT - A data was then processed using motion correction algorithm that was tailored for the modified Lissajous scanning pattern to correct the eye motion artifacts in the en face plane. The OCT - A slab between the inner limiting membrane and outer plexiform layer was segmented to provide an enhanced motion - corrected en face OCT - A image of the inner retinal flow. The comparison of the en face OCT - A images with and without motion correction show that our motion correction algorithm corrected the eye motion artifacts effectively. A motion - corrected en face OCT - A image of target layer is presented to confirm our method.
