Abstract
In a process for optical coherence tomography a plurality of first OCT slice images, in each first slice image representing a different slice of an object, are recorded. Subsequently a reference figure that is representative of the three-dimensional contour of at least one structural feature of the object in a given three-dimensional coordinate system is ascertained by feature recognition of the at least one structural feature in the first slice images. Then a plurality of second OCT slice images, each second slice image representing a different slice of the object, are recorded. At least a fraction of the second slice images are displaced in the coordinate system until each second slice image is in feature overlap with the reference figure. Lastly, a set of three-dimensional OCT image data is generated at least from the feature-overlapped second slice images.
