Segmentation system for segmenting a blood vessel in the interactive in angiographic image data

摘要

The present invention, in order to segment the blood vessel 2 interactively in angiographic image data 3, about the segmentation device 10. The segmentation unit 10, the current segmentation 4, a predetermined effect on the value of the blood flow parameters calculated on the basis of the current segmentation 4, as significant position 5, of a blood vessel 2 in the angiographic image data 3 of the current segmentation 4 It has a significant position determination unit 11 for determining one or more locations, and a display unit 12 for displaying the significant position 5 to the operator. Thereby, the operator, his / her effort segmentation can be guided so as to focus on the most relevant their position in the current segmentation 4 for accuracy of the calculation of the value of the blood flow parameters. Thus, during the segmentation procedure, burden on the operator is allowed to be reduced
