1. A method for acquiring 3-dimensional images of coronary vessels, the coronary vessels (11) moving in a cyclic motion, the method comprising:

  • acquiring a plurality of 2-dimensional X-ray images (13) of an acquisition region comprising the coronary vessels, wherein at least three 2-dimensional X-ray images are acquired in a substantially same phase of the cyclic motion under different projection angles;

    generating at least one 3-dimensional centerline model (15) of the vessels from the at least three 2-dimensional X-ray images acquired in the substantially same phase of the cyclic motion under different projection angles;

    generating 2-dimensional fits of the at least one 3-dimensional centerline model onto the corresponding 2-dimensional X-ray images acquired in the substantially same phase of the cyclic motion;

    deriving local vessel diameters (w) from the 2-dimensional fits with respect to the different projection angles;

    generating a 3-dimensional hull model of the vessels based on the derived local vessel diameters.
