METHOD FOR CORRECTING PATIENT MOTION WHEN OBTAINING RETINA VOLUME USING OPTICAL COHERENCE TOMOGRAPHY

摘要

A computer-implemented method of correcting for motion of a sample during OCT imaging obtains a series of cross-sectional volume scans through the sample at different positions on a first coordinate axis, obtains at least two cross-sectional alignment scans in planes intersecting said volume scans at an angle, and stores the alignment scans and the volume scans in memory. The alignment scans are matched to the volume scans at lines of intersection thereof to determine the relative displacement of the volume scans to the sample due to sample motion. The relative displacement is used to correct for motion of the sample between successive volume scans.
