Examples of artifact types encountered during optical coherence tomography (OCT) imaging. The figure includes both good-quality (A) and poor-quality (B-H) enface scans, with corresponding cross-sectional B-scans for poor-quality examples. White arrows indicate the location of the artifact, and orange dotted lines mark the location of the B-scan. Panels show: (A) Good-quality scan; (B) Motion artifact; (C) Shadow artifact; (D) Off-center artifact; (E) Refractive shift; (F) Out-of-boundary artifact; (G) Tilt artifact; (H) Low-signal artifact.
