A method and a corresponding system for optical coherence tomography acquires a first image in a region of a first plane of an object by optical coherence tomography equipment, and the first image is displayed on a display device. To facilitate a reliable and time-saving examination with straightforward handling, a second plane of the object is selected on the basis of the first image that is displayed on the display device, wherein the second plane of the object is different from the first plane of the object, and a second image is acquired in the region of the selected second plane of the object by the optical coherence tomography equipment.
