PROBLEM TO BE SOLVED: To provide an artery blood vessel detection device capable of surely extracting an artery in a short axis cross section image.SOLUTION: An artery blood vessel detection device comprises: a compression release state determination control part 102 for determining a compression state and a release state of a biological tissue using a movement vector which indicates movement of a pixel between frames, from a moving image of a short axis cross section image an artery blood vessel determination control part 104 for determining that the blood vessel is an artery blood vessel 20, based on a fact that, an area of a lumen N of a tubular organ which exists in the short axis cross section image in the compression state satisfies a preset artery blood vessel lumen determination condition and an artery blood vessel tracking control part 110 for creating a template of whole artery blood vessel based on a position of the lumen of the determined artery blood vessel 20, then tracking movement of the lumen of the artery blood vessel in a step in which the short axis cross section image shifts to a release state from the compression state, using the template, then identifying the artery blood vessel in the short axis cross section image in the release state. Therefore, the artery blood vessel 20 can be accurately and automatically extracted from the short axis cross section image Ga.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2017,JPO&INPIT【課題】短軸断面画像中の動脈を確実に抽出することができる動脈血管検出装置を提供する。【解決手段】短軸断面画像の動画から、フレーム間の画素の移動を示す移動ベクトルを用いて生体組織の圧迫状態および解放状態を判定する圧迫解放状態判定制御部102と、前記圧迫状態の前記短軸断面画像内に表れる管状臓器の内腔Nの領域が予め設定された動脈血管内腔判定条件を満たすことに基づいて動脈血管20であると判定する動脈血管判定制御部104と、判定された動脈血管20の内腔の位置に基づいて動脈血管全体のテンプレートを作成し、前記テンプレートを用いて前記短軸断面画像が圧迫状態から解放状態へ移行する過程で前記動脈血管の内腔の移動を追跡し、解放状態における短軸断面画像内において動脈血管を特定する動脈血管追跡制御部110とを、含む。これにより、短軸断面画像Ga内から動脈血管20を正確に且つ自動的に抽出することができる。【選択図】図6
