1. A method of constructing a blood vessel map, the method
receiving, by a blood vessel map construction apparatus, a TOF image of the object;
extracting, by the blood vessel map constriction apparatus, a blood vessel stem, a center line of a blood vessel, and features of the center line included in the TOF image, and detecting branch points of the blood vessel based on the extracted blood vessel stem, center line of the blood vessel, and features of the center line;
searching, by the blood vessel map construction apparatus, a reference blood vessel image corresponding to the TOF image in consideration of location information or curvature information of the branch points;
calculating a similarity between the TOF image and the reference blood vessel image; and
registering the TOF image in the blood vessel map based on the similarity.
