1. A method for segmenting medical images of a non-planar surface of an object, in particular of a heart valve, the method comprising the following steps: detecting a surface boundary, which delimits the non-planar surface of the object, creating a model surface, which is spanned between the surface boundary, correcting the model surface by means of distance information, which contains information about distance(s) between the model surface and the non-planar surface of the object, until a corrected model surface is generated, and depicting the corrected model surface.
