| In the later 1990s, Tim McInerney and other scholars proposed the method of auto-adapted deformable model (Topological Adaptable Snakes, the T-Snake model), which is unified the technology of deformable models and ACID (Affine Cell Image Decomposition). The T-Snake model is a deformable model with invariable topology, it has inherited many merits of the Snake models, but which is more important is that the T-Snake model will changes its topology after a small deformation, thus the influence of the initial outline is weaker to the T-Snake model than to the snake models, which is more important is that the T-Snake model can auto-adapted change its topology according to edge information of the image, so the T-Snake model is strong regarding complex topology image processing and adaptiveness. In recent years, the T-Snake model has gradually become the research hot spot of the correlation domain, such as image division, three dimension reconstruction, edge detection and so on. And now scholars main research the structure of the internal and external force and the deformation evolutionary process value realization of the T-Snake.Intravascular Ultrasound (IVUS) is one kind of diagnosis and appraisal method of the scleratheroma, it has the merits of safe, real-time, no damages and so on. Detecting border for Intravascular ultrasound images and doing the further analysis and processing can not only carry on accurate measurement to the area of of blood vessel, and can also find the early scleratheroma plaques of coronary artery, it can also show the shape of the plaques and measure such parameters as composition of the plaque and centrifugal distance, wall thickness in real time, more important, images after the 3D reconstruction can recognize the early scleratheroma plaques, discover the morphological structure of the plaques in real time, and detect the ingredient and eccentricity of the plaques. So the 3D reconstruction of Intravascular ultrasound images... |
