Abstract

In a process for optical coherence tomography a plurality of first OCT slice images (34) each first slice image representing a different slice of an object (12) are recorded. Subsequently a reference figure (44) that is representative of the three dimensional contour of at least one structural feature (36) of the object (12) in a given three dimensional coordinate system x y z is ascertained by feature recognition of the at least one structural feature (36) in the first slice images (34). Then a plurality of second OCT slice images (46) each second slice image representing a different slice of the object (12) are recorded. At least a fraction of the second slice images (46) are displaced in the coordinate system x y z until each second slice image (46) is in feature overlap with the reference figure (44). Lastly a set of three dimensional OCT image data is generated at least from the feature overlapped second slice images (46).
