Abstract

A method for obtaining an image of a tooth obtains an area image of the tooth (20) surface and identifies a region of interest from the area image by positioning a marker (146) on the area image. The marker (146) corresponds to at least a portion of the region of interest and identifies a scanning area. An optical coherence tomography (OCT) image is then obtained over the scanning area.
