Abstract

Optical coherence tomography (OCT) based angiography devices were introduced for research purposes in 2014 and are now appearing in clinical settings. OCT-A, as this is known, exhibits what is referred to as the shadowgraphic flow projection artifact, which causes blood vessels to have an elongated appearance in A-scans. Existing approaches for resolving this artifact rely on the flow signal in superficial layers along the same A-scan to remove projection artifacts in deeper layers, essentially treating the problem as a 1D correction. We however, propose to use characteristics of the projection artifacts in 3D. Specifically, we use the tailing effect of the shadowgraphic flow projection artifact to remove the artifacts in the inner retina. We demonstrate that our projection artifact suppression method (PAS-OCTA) produces better OCT-A images when compared with a previously reported correction method (PR-OCTA), both qualitatively and quantitatively.
