1. A method, comprising:
- receiving into at least one processor a first set of one or more two-dimensional extraluminal images of blood vessels of a subject;
generating a two-dimensional extraluminal road map image indicating a longitudinal path of at least one of the subject'"'"'s blood vessels, by automatically;
deriving at least one two-dimensional image from the first set of images of the blood vessels, based upon visibility of at least a portion of the blood vessels in the set of images;
determining a location of one or more edge lines corresponding to a boundary of the blood vessel in the derived two-dimensional image;
determining a location of a center line corresponding to the longitudinal path of the blood vessel in the derived two-dimensional image, wherein the location of the center line is determined using the location of the one or more edge lines; and
connecting, after determining location of the center line using the location of the one or more edge lines, disconnected portions of the center line by comparing locations of the disconnected portions;
acquiring a second set of one or more extraluminal images of the subject'"'"'s blood vessels;
registering the extraluminal road map image to the one or more extraluminal images belonging to the second set of images; and
generating an output by the processor, based on the registering of the extraluminal road map image to the one or more extraluminal images belonging to the second set of extraluminal images.

Abstract
Apparatus and methods are described for receiving into at least one processor a set of images of blood vessels of a subject. A road map of the subject'"'"'s blood vessels is generated, by automatically (a) deriving at least one image from the set of images of the blood vessels, based upon visibility of at least a portion of the blood vessels in the set of images, and (b) in the derived image, determining a location of edge lines of at least some of the portion of the blood vessels in the image. An output is generated by the processor, based on the road map. Other embodiments are also described.
