1. A device for the three-dimensional reconstruction of the flow conditions in a vascular system (3) with the aid of two-dimensional projections of the vascular system during a contrast-medium injection, comprising an imaging device (1) for producing two-dimensional projection pictures of the vascular system (3) taken from different directions (A, Bi, C);

  • an injection device (5) for the controlled injection of a contrast medium into the vascular system (3);

    a control unit (6) that is coupled to the imaging device (1) and that is designed to drive the imaging device in accordance with the following steps;

    a) production of projection pictures taken from the same projection direction (A) at a high picture-taking rate during the inflow of the contrast medium after a contrast-medium injection;

    b) rotation of the imaging device around the vascular system (3) and production of projection pictures taken from different directions (Bi) while the vascular system (3) is filled with contrast medium.
