Abstract
(EN)
This blood vessel position display device (1) is provided with: an image processing device (31) that performs image processing on an analysis image of a target portion (2) and acquires blood vessel information including the position and shape of blood vessels included in the target portion (2); a sorting device (32) that sorts, as suitable blood vessels, the blood vessels in which parameters obtained from the blood vessel information satisfy a certain condition; an image generation device (33) that generates a projection image including indication lines having at least lengths corresponding to the suitable blood vessels; and a projection device (40) that projects the projection image to the target portion (2), by making the positions of the indication lines correspond to the positions of the suitable blood vessels.
(FR)
La présente invention concerne un dispositif d’affichage de position de vaisseau sanguin (1) pourvu : d’un dispositif de traitement d’image (31) qui effectue le traitement d’image sur une image d’analyse d’une portion cible (2) et qui acquiert les informations de vaisseau sanguin comprenant la position et la forme des vaisseaux sanguins compris dans la portion cible (2) ; d’un dispositif de tri (32) qui trie, sous la forme de vaisseaux sanguins appropriés, les vaisseaux sanguins dans lesquels les paramètres obtenus des informations de vaisseau sanguin satisfont une certaine condition ; d’un dispositif de génération d’image (33) qui génère une image de projection comprenant des lignes d’indication ayant au moins des longueurs correspondant aux vaisseaux sanguins appropriés ; et d’un dispositif de projection (40) qui projette l’image de projection vers la portion cible (2), en faisant correspondre les positions des lignes d’indication aux positions des vaisseaux sanguins appropriés.
(JA)
血管位置表示装置(1)は、対象部位(2)の解析用画像を画像処理して、対象部位(2)に含まれる血管の位置及び形状を含む血管情報を取得する画像処理装置(31)と、血管情報から得られるパラメータが一定の条件を満たす血管を適合血管として選別する選別装置(32)と、適合血管と少なくとも長さを対応させた表示線を含む投影画像を生成する画像生成装置(33)と、適合血管の位置に表示線の位置を対応させて投影画像を対象部位(2)に投影する投影装置(40)とを備える。
