A method of creating a surface model of an intracranial aneurysm in an artery having a lumen, the aneurysm having a neck and a dome and the virtual reconstruction of the parent artery across the lateral extension of the aneurysm neck. The method includes the steps of: determining a center and radius of the artery over the lateral extension of the aneurysm; determining the boundary points that mark the boundary between the aneurysm neck and the artery; determining the angle of the aneurysm neck with respect to the artery, for various cross sections of the neck; determining the length of the neck; determining the height of the dome; estimating the area of the neck; and creating the surface model of the intracranial aneurysm in the artery, using the results from the previous steps.
