Abstract

In the method according to at least one embodiment of the invention, a first segmentation of a structure in an image data record is firstly carried out, and a first final segmentation result is obtained therefrom. A region in the image data record is selected based on the first final segmentation result obtained. A first band is placed at a first, outwardly pointing distance from the selected region. This first band characterizes a background region. A second band is placed at a second, inwardly pointing distance from the projected first final segmentation result of the first segmentation. This second band characterizes a structure region. A further segmentation is carried out based on the characterized background region and the characterized structure region, and the final segmentation result of the further segmentation is saved and/or displayed. Furthermore, an image processing unit for carrying out the method is disclosed.
