A method and corresponding system for optical coherence tomography includes optical coherence tomography equipment that acquires at least two two-dimensional initial images of an object in planes of the object that are spaced apart from one another, in particular running parallel to one another, wherein the initial images each include a plurality of initial image values. In order to assure an examination of the object in the case of medical applications that is as reliable as possible, an interpolation of the initial image values of the at least two two-dimensional initial images is performed in three-dimensional space, wherein interpolation values are obtained that form a two-dimensional final image.
