1. A method for use with an endoluminal data-acquisition device having a radiopaque portion coupled thereto, the method comprising:

  • while the endoluminal data-acquisition device is being moved through the lumen, acquiring a plurality of endoluminal data points of the lumen using the endoluminal data-acquisition device;

    using an extraluminal imaging device, acquiring a first extraluminal image of the lumen, at a time associated with an acquisition of the first endoluminal data point by the endoluminal data-acquisition device, the first extraluminal image including an image of the radiopaque portion at a first location within the lumen;

    using the extraluminal imaging device, acquiring a second extraluminal image of the lumen, at a time associated with an acquisition of the second endoluminal data point by the endoluminal data-acquisition device, the second extraluminal image including an image of the radiopaque portion at a second location within the lumen; and

    using at least one processor;

    generating a combined extraluminal image of the lumen that contains images of the radiopaque portion at the first and second locations within the lumen, by co-registering the first and second extraluminal images with each other;

    identifying at least one location on the combined extraluminal image as corresponding to a location within the lumen at which a given one of the endoluminal data points was acquired, by identifying the first and second locations of the radiopaque portion within the combined extraluminal image; and

    generating an output on an output device, in response thereto.
