Volumetric OCT image centered on the optic nerve of a healthy subject acquired in 1 second using constant linear velocity spiral scanning (protocol #3 in Table 1). The volume was oversampled along the angular dimension by 4x and 4 adjacent A-scans were averaged to generate averaged circular B-scans. (a) SVP generated from the volumetric data set. Dashed colored lines correspond to the locations of the circular B-scans. (b) Un-averaged circular B-scan. (c-d) 4x averaged circular B-scans.
