Abstract
Failure part is detected using calculated structure information. In one embodiment, the failure part is detected by comparing path node positions, numbers of node positions, branch lengths, and branch positions. That is, it is detected that although nodes a2 and a3 exist in structure information N in phase N, corresponding nodes do not exist in the preceding phase N−1 or the subsequent phase N+1. Moreover, it is detected that a node a1 existing in the preceding phase N−1 and a node a5 existing in the subsequent phase N+1 do not exist in a corresponding part a4 in the structure information N in the phase N.
Claims20
An image processing method comprising:
- providing at least one processor;
- acquiring structure information from each volume data in a group of volume data including a plurality of phases, each of the structure information corresponding to each volume data in the group of volume data, and each of the structure information including at least one of a path, a node of the path and a branch of the path;
- and
- detecting an anomaly in the structure information by comparing the structure information of different volume data in the group of volume data with each other, wherein the step of comparing includes determining the existence/non-existence of at least one of the node of the path and the branch of the path,
- wherein the steps of acquiring and detecting are performed by the at least one processor.
A computer readable medium storing a program including instructions for permitting a computer to perform image processing, said instructions comprising:
- acquiring structure information from each volume data in a group of volume data including a plurality of phases, each of the structure information corresponding to each volume data in the group of volume data, and each of the structure information including at least one of a path, a node of the path and a branch of the path;
- and
- detecting an anomaly in the structure information by comparing the structure information of different volume data in the group of volume data with each other, wherein said comparing includes determining the existence/non-existence of at least one of the node of the path and the branch of the path.
An image processing apparatus storing a program for executing an image processing, the image processing comprising:
- acquiring structure information from each volume data in a group of volume data including a plurality of phases, each of the structure information corresponding to each volume data in the group of volume data, and each of the structure information including at least one of a path, a node of the path and a branch of the path;
- and
- detecting an anomaly in the structure information by comparing the structure information of different volume data in the group of volume data with each other, wherein said comparing includes determining the existence/non-existence of at least one of the node of the path and the branch of the path.
