Abstract
The invention provides a method for 3D modeling of a three-dimensional tubular structure of an examination object from 2D projection images (D) of the structure taken from different projection directions. The method has the following steps: reconstruction of a 3D image from the 2D projection images (D); selection of at least one 3D central line point (MO) in the 3D image, said 3D central line point being located in the structure; segmentation of 3D central line points (M) of the structure in the 3D image; forward projection of the 3D central line points (M), which have been segmented in the 3D image, into 2D projection images (D'); determination of border points of the structure in the 2D projection images (D′) on the basis of 3D central line points (Z) that have been projected in; and back-projection of the border points from the 2D projection image (D′) into the 3D image.
