Abstract:
(EN) A virtual stent placement device, method, and program that simplify the work involved in virtually placing a stent in a blood vessel that has been extracted from a medical image. According to the present invention, an extraction unit (22) extracts a blood vessel region (30) from a three-dimensional image (V0). A display control unit (26) displays a three-dimensional image (V1) that includes the blood vessel region (30). An information acquisition unit (23) acquires information about: the diameter of a virtual stent that is to be placed in the blood vessel region (30); the longest contour of the virtual stent; and a start position (S1) for the placement of the virtual stent. On the basis of the start position (S1), a placement unit (24) places the virtual stent, the longest contour (L0) of which follows a longest contour line of the blood vessel region (30), in the blood vessel region (30).
(FR) L'invention concerne un dispositif, un procédé et un programme de pose d'une endoprothèse virtuelle qui simplifient le travail impliqué lors de la pose d'une endoprothèse de manière virtuelle dans un vaisseau sanguin qui a été extrait d'une image médicale. Selon la présente invention, une unité d'extraction (22) extrait une région (30) de vaisseau sanguin d'une image tridimensionnelle (V0). Une unité de commande d'affichage (26) affiche une image tridimensionnelle (V1) qui comprend la région (30) de vaisseau sanguin. Une unité d'acquisition d'informations (23) acquiert des informations concernant : le diamètre d'une endoprothèse virtuelle qui doit être placée dans la région (30) de vaisseau sanguin ; le contour le plus long de l'endoprothèse virtuelle ; et une position de départ (S1) pour la pose de l'endoprothèse virtuelle. Sur la base de la position de départ (S1), une unité de pose (24) pose l'endoprothèse virtuelle, dont le contour le plus long (L0) suit la ligne de contour la plus longue de la région (30) de vaisseau sanguin, dans la région (30) de vaisseau sanguin.
(JA) 仮想ステント設置装置、方法およびプログラムにおいて、医用画像から抽出された血管に仮想的にステントを設置する際の作業を簡易なものとする。抽出部(22)が、3次元画像(V0)から血管領域(30)を抽出する。表示制御部(26)が、血管領域(30)を含む3次元画像(V1)を表示し、情報取得部(23)が、血管領域(30)に設置する仮想的なステントである仮想ステントの径、仮想ステントの最大輪郭長および仮想ステントを設置する際の開始位置(S1)の情報を取得する。設置部(24)が、開始位置(S1)を基準として、血管領域(30)の最大輪郭線に沿った最大輪郭長(L0)を有する仮想ステントを血管領域(30)に設置する。
