Abstract: Optical Coherence Tomography(OCT) system may cause dislocations and distortions of the collected image volumetric? data when proceeding dynamic 3D imaging because of the involuntary movements of eyeball, which will result in misdiagnoses during clinical diagnosis. The optic disk region of human eye has much more complex structure and further more blood vessels compared with macular region, which means the conventional image correction method aiming at macular region can not apply to optic disk region. In this paper, we propose a X direction artifact correcting method based on pixel row correlation matching algorithm of C-Scan, specific to the structural features of human eye optic disk region OCT images. Moreover, using this method, we can estimate whether the image sequences with motion artifacts have part image repetition or missing or not, and we can further confirm the positions and numbers of repetition and missing with the help of Y direction 2D scan images. Model verification indicates that this method can effectively rebuild the real image sequences and truly reflect the physiology structure of retina.
