Abstract

Abstract Translated from Japanese 【課題】血管などの管腔臓器の芯線及び輪郭の３次元的な位置情報を短い処理時間で精度良く抽出して、診断に有用な情報を確実に提供する。 【解決手段】画像処理装置は、記憶手段２１に記憶された被検体の３次元画像データ内の所望の管状構造物（例えば血管）の領域を、操作者から指定された始点及び終点の範囲にわたって３次元的に抽出する領域抽出手段２３と、抽出された管状構造物の芯線を３次元画像データから３次元的に抽出する芯線抽出手段２４と、抽出された芯線と３次元画像データとに基づいて肝臓構造物の輪郭を３次元的に抽出する輪郭抽出手段２９とを備える。 【選択図】 図２ An object of the present invention is to accurately extract three-dimensional position information of a core line and a contour of a luminal organ such as a blood vessel in a short processing time and to surely provide useful information for diagnosis. An image processing apparatus extends a region of a desired tubular structure (for example, a blood vessel) in three-dimensional image data of a subject stored in a storage unit over a range of a start point and an end point specified by an operator. A region extracting means 23 for three-dimensionally extracting, a core line extracting means 24 for three-dimensionally extracting a core line of the extracted tubular structure from the three-dimensional image data, and a core line and three-dimensional image data based on the extracted core line. And a contour extracting means 29 for three-dimensionally extracting the contour of the liver structure. [Selection] Fig. 2
