1. Process for optical coherence tomography, comprising: recording a plurality of first OCT slice images, each first slice image representing a different slice of an object, ascertaining 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 by feature recognition of the at least one structural feature in the first slice images, recording a plurality of second OCT slice images, each second slice image representing a different slice of the object, displacing at least a fraction of the second slice images in the coordinate system until each second slice image is in feature overlap with the reference figure, and generating a set of three-dimensional OCT image data at least from the feature-overlapped second slice images.
