Abstract :
A method is described for the determination of angiographic image-formation geometry from the images for the purposes of providing real-time interactive tracking of surgical position on the angiograms. While we presume the use of extrinsic fiducial markers, no restraint is place on the imaging geometry other than the markers must be both distinct and visible on the film
