摘要：

[Problem] To delete an abnormal protrusion region from a three-dimensional image of a blood vessel.[Solution] On the basis of three-dimensional blood vessel data representing the three-dimensional shape of the blood vessel, this control apparatus 102 identifies center lines of the blood vessel, identifies a center line of a protruding portion of the blood vessel from among the center lines, and identifies a center line that branches off from the center line of the protruding portion. Then, for three-dimensional blood vessel data of the blood vessel corresponding to the branching center line, the control apparatus 102 defines a cylindrical coordinate system with the circumferential direction of the blood vessel from the center line, the radial direction of the blood vessel from the center line, and the direction of the center line as coordinate axes, and converts blood vessel data expressed in the cylindrical coordinate system into blood vessel data in an orthogonal coordinate system. In the blood vessel data in the orthogonal coordinate system, the control apparatus 102 uses a coordinate value along the radial-direction coordinate axis for a first coordinate value along the center-line-direction coordinate axis and a coordinate value along the radial-direction coordinate axis for a second coordinate value along the center-line-direction coordinate axis to interpolate coordinate values along the radial-direction coordinate axis from the first coordinate value to the second coordinate value, and converts the resulting blood vessel data in the orthogonal coordinate system into blood vessel data in the cylindrical coordinate system.Le problème de la présente invention vise à supprimer une région de protubérance anormale d'une image tridimensionnelle d'un vaisseau sanguin. La solution selon l'invention, sur la base de données de vaisseau sanguin tridimensionnel représentant la forme tridimensionnelle du vaisseau sanguin, cet appareil de commande (102) identifie des lig
