1. A method for 3D angio-volume reconstruction of a three-dimensional subject based on 2D projection exposures, comprising the steps of:

  • obtaining a plurality of 2D mask images of a three-dimensional subject with no contrast agent in said subject and producing a 3D angio-volume dataset V1 based on said 2D mask images;

    obtaining a plurality of 2D fill images of said subject, with contrast agent in said subject, and producing a 3D angio-volume dataset V2 based on said 2D fill images, said dataset V2 containing a vessel tree made visible by said contrast agent; and

    isolating said vessel tree in said dataset V2 by segmentation, scaling the isolated vessel tree to obtain a scaled isolated vessel tree, and adding said scaled isolated vessel tree to said dataset V1 to produce a 3D angio-volume reconstruction without shadowing artifacts.
