9. A method for imaging an artery contained in an arterial tree, the artery having an axis, comprising:
a generating a three-dimensional reconstruction of the arterial tree from two or more angiographic images of the arterial tree obtained from different perspectives wherein said images are produced by taking images after moving the angiographic source and detector into a required orientation defined by said different perspectives relative to a subject's body;
b determining an orientation of the axis of the artery in the arterial tree;
c calculating from the three-dimensional reconstruction of the arterial tree at least two perspectives of the artery perpendicular to the axis of the artery;
d obtaining at least one angiographic image at each of the calculated perspectives from the previously obtained images if images were taken at the calculated perspectives, or by obtaining additional images that are produced by taking images after moving the angiographic source and detector into a required orientation defined by said calculated perspectives relative to the subject's body, if images taken at the calculated perspectives are not available from the previously obtained images; and
e generating a three dimensional reconstruction of the artery from angiographic images obtained essentially from the calculated perspectives.
