Abstract
The invention relates to a method for the reconstruction of a three-dimensional model of a vascular tree from two-dimensional X-ray projection images (A, B, C) that are taken from different spatial directions. On a first projection image (A) at least one reference point (C) is specified. The gray-value profiles along the epipolar lines (E, E) for said reference point (C) in other projection images (B, C) are then projected on the projection line (L) of the reference point (C) and added there punctiformly to form a sum profile (S). The sum profile (S) has an extreme, for example, a gray-value minimum, at the position of the space point (C) belonging to the reference point (C). In this way, it is possible to reconstruct semiautomatically a vascular tree from X-ray projections.
