Claim 3:
4. The method as claimed in claim 1, wherein the point-cloud of 3D points comprises:
(i) a first set of points which represent the intersection points between
(a) projection lines from a plurality of points on a 2D vessel centerline from a first 2D image to the first x-ray source,
(b) projection lines from a plurality of points on a 2D vessel centerline from a second 2D image to the second x-ray source,
(c) projection lines from a plurality of points on a 2D vessel centerline from a third 2D image to the third x-ray source, and optionally
(d) projection lines from a plurality of points on a 2D vessel centerline from a fourth 2D image to the fourth x-ray source; and

(ii) a second set of points which represent nearest orthogonal points between projection lines defined in (a), (b), (c), and optionally (d), if the projection lines do not intersect.
