Abstract
Optical coherence tomography (OCT) has revolutionized diagnostics in ophthalmology. Montaging of multiple OCT volumes allows for wide field retinal volumes. However, OCT requires an operator to align the scanner and requires patient cooperation to fixate on multiple targets, one for each volume in the montage. We have developed a robot-mounted OCT scanner that automatically aligns with the subjects’ eye by compensating motion and gaze error at multiple entry angles, allowing acquisition of volumes from multiple regions of interest without chin or fore rest stabilization or a fixation target. We demonstrate our system by montaging a retinal volume acquired from a free-standing subject.
