Abstract:
1. A method of imaging an eye with an optical coherence tomography (OCT) system, said system having a light source for generating a beam of radiation that is scanned over the eye with a scanner that generates scanner coordinates, said method comprising: scanning the beam in a raster pattern consisting of a plurality of parallel first lines, each first line including a plurality of A-scans; scanning the beam along at least one second line, said second line including a plurality of A-scans, said second line being oriented along an axis that is not parallel to the first lines, with certain of the A-scans of the second line being close to certain A-scans in the first lines; comparing the A-scans of the first and second lines that are near each other to determine any differences between the generated scanner coordinates and expected scanner coordinates, said differences being associated with eye movement; and using the determined differences to adjust image information derived from the A-scans to compensate for eye movement.
