Abstract
A method for improving an OCT image of an object such as the retina of an eye, using optical coherence tomography by an imaging beam path. In order to suppress shadowing effects due to a surgical instrument moved in the imaging beam path, a time series of OCT images is produced. For an OCT image to be corrected, an area of the object lying in the image and shadowed by the instrument is determined. Another earlier OCT image in which the area of the object is not shadowed is searched in the time series. Image information for the area of the object is read from the earlier OCT image. A corrected OCT image is produced by inserting the read-image information into the OCT image to be corrected, wherein in the OCT image to be corrected, the image information replaces the area of the object which is shadowed by the instrument.
