PROBLEM TO BE SOLVED: To generate an image that allows recognition of not only the situation of one branch in a conduit but also the situation of a branch ahead of it, and allows instantaneous recognition of positional relationship between a prescribed branch and the next branch as well, in a medical image diagnosis support device for generating an image for supporting insertion of an endoscope to a conduit inside a body such as the bronchus.SOLUTION: A medical image diagnosis support device includes: a three-dimensional image acquisition part 11 for acquiring a three-dimensional image obtained by imaging a subject a graph structure generation part 12 for generating a graph structure of a linear structure included in the three-dimensional image and a branch information image generation part 14 for generating, for each of a plurality of branch points included in the graph structure, a projection image in which a branch destination from the branch point is projected on a two-dimensional plane including the branch point, and generating a branch information image in which the generated projection image for each branch point is superimposed.COPYRIGHT: (C)2013,JPO&INPIT【課題】気管支のような体内の管路への内視鏡の挿入を支援する画像を生成する医用画像診断支援装置において、管路における1つの分岐の様子だけでなくその先の分岐の様子も把握することができ、かつ所定の分岐と次の分岐との位置関係も即座に把握することができる画像を生成する。【解決手段】被検体を撮影して得られた3次元画像を取得する3次元画像取得部11と、3次元画像に含まれる線状構造物のグラフ構造を生成するグラフ構造生成部12と、グラフ構造に含まれる複数の分岐点のそれぞれについて、その分岐点からの分岐先をその分岐点を含む2次元平面上に投影した投影画像を生成し、その生成した分岐点毎の投影画像を重ね合せた分岐情報画像を生成する分岐情報画像生成部14とを備える。【選択図】図1
