Abstract
A method and apparatus are disclosed for integrating optical coherence tomography (OCT) and very high frequency ultrasound (VHFU) imaging systems. An OCT probe and reference arm are mounted along with an ultrasound probe on a carriage capable of rotational, linear, and/or arcuate motion. The probe carriage may be immersed in water or other suitable medium. The OCT and VHFU probes move about the cornea surface such that the probe axes are substantially perpendicular relative to the cornea surface throughout a scan. The probes are able to be scanned in an arcuate path across the entire cornea surface. The method and apparatus disclosed are also directed towards providing a positioning mechanism and scan head comprising an arcuate guide track wherein only an OCT probe is mounted on the probe carriage. This embodiment allows the OCT probe beam to remain substantially perpendicular to the cornea and lens surfaces.
