Abstract
Apparatus and methods are described for use with an endoluminal data-acquisition device having a radiopaque portion coupled thereto, including, 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. A combined extraluminal image of the lumen is generated that contains images of the radiopaque portion at first and second locations within the lumen, by co-registering first and second extraluminal images with each other. At least one location on the combined extraluminal image is identified 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. An output is generated, in response thereto. Other applications are also described.
