Abstract
(EN)
The present specification discloses a method for constructing a blood vessel map, the method comprising: a step in which a device for constructing a blood vessel map receives a TOF image captured of a subject; a step in which the device for constructing a blood vessel map extracts blood vessel stems, center lines of blood vessels, and features of the center lines, which are included in the TOF image, and detects branch points of the blood vessels on the basis of the extracted blood vessel stems, center lines of blood vessels, and features of the center lines; a step in which the device for constructing a blood vessel map searches for a reference blood vessel image corresponding to the TOF image in consideration of location information and curvature information on the branch points; a step for calculating the similarity between the TOF image and the reference blood vessel image; and a step for registering the TOF image in a blood vessel map on the basis of the similarity.
