Abstract
The present invention relates to a method and device for automatical segmentation of medical images of a non-planar surface of an object, in particular of a heart valve, including 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 containing information about the distance 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, where the correction of the model surface is preferably carried out by means of three- or four-dimensional image data sets, by orienting the three-dimensional volume-rendering of the object essentially perpendicular to the model surface, so that the information about the distance between the model surface and the non-planar surface of the object can be evaluated, until the corrected model surface has been produced.
