1. A method of finding the location of an occluded portion of a blood vessel relative to a three-dimensional angiographic image of a subject'"'"'s vasculature, the method comprising:

  • deriving, from three dimensional image data associated with an angiographic image, a series of two dimensional images in planes substantially transverse to the direction of an occluded portion of a blood vessel that is displayed in the angiographic image;

    identifying, via a user-input device, a location within the occluded portion of the blood vessel on each of the series of displayed two dimensional images derived from the three dimensional image data; and

    determining, from the locations identified on each of the two dimensional images, a construction of the occluded portions of the blood vessel, and displaying the construction on the three-dimensional angiographic image to indicate the location of the occluded portions.
