ABSTRACT:
The invention relates to a method for tomographically displaying a cavity by optical coherence tomography (OCT) and to an OCT device, wherein the path length of a measuring light beam in the catheter can change as a result of a movement of the catheter and brings about a change in the display scale, wherein a possible change in the path length of the measuring light beam in the event of a movement of the catheter is electronically determined and automatically compensated.
