摘要： Plural sectional images are acquired at a plurality of slice positions arranged in a predetermined direction in a subject. Each of the plural sectional images acquired by the image acquisition section is binarized based on a predetermined reference image density. Each image included in the sectional images binarized by the binarizing section is classified into a first image group having the images inside the subject and a second image group having the images outside the subject, based on the relative position of the each image from the other images in the same sectional image and also the relative position of the each image from other images contained in another sectional images.

摘要： A predetermined structure repeatedly branching from an origin and extending in directions away from the origin in such a manner to become wider is extracted, as a candidate of a tree structure defined by a plurality of nodes including a root node corresponding to the origin and a plurality of edges, from medical image data. A tree structure is created by reevaluating the definition of the tree structure, with respect to each of the plurality of nodes defining the candidate of the tree structure, by using a cost function that weights a probability that the plurality of nodes are connected to each other by evaluating a relationship between each of the plurality of nodes and the root node based on a geometric characteristic that the predetermined structure repeatedly branches from the origin and extends in directions away from the origin in such a manner to become wider.

摘要： Tree structures corresponding to a first linear structure and a second linear structure are constructed from medical image data including the first linear structure and the second linear structure, each repeatedly branching from an origin and extending in directions away from the origin in such a manner to become wider. Each of a first root node corresponding to a root node in the first tree structure and a second root node corresponding to a root node in the second tree structure is connected to each node, based on the characteristic that each of the first and second linear structures repeatedly branches from the origin and extends in directions away from the origin in such a manner to become wider, by using, with respect to each node, a cost function that weights a cost representing a probability of connection of each of a plurality of edges connectable to each node.
