1. A method for segmentation of anatomical structures from a sequence of 3D image data records recorded in a time sequence, comprising: initially segmenting, by a computing device, an anatomical structure from a first of the 3D image data records, during the segmentation of the anatomical structure in further 3D image data records, at least one of a plurality of search areas of the segmentation being restricted and segmentation parameters associated with the three-dimensional relationships from other 3D image data records being used, on the basis of known spatial conditions of the structure to be segmented, with respect to anatomical objects located in the surrounding area and of results of the segmentation from a respective previous 3D image data record in the sequence from which the structure has already been segmented, wherein at least one of at least one known anatomically significant point and at least one known anatomically significant surface is identified in the first 3D image data record, and wherein a distance relative to at least one of the anatomically significant point and the anatomically significant surface is taken into account in the restriction of the search areas and defined at a minimum.
