Abstract

An approach for tracking dynamic arterial vessels in X-ray ANGIOGRAM sequences is developed. Firstly, original images are segmented into binary ones by using multi-scale filtering technique. Then, a discrete DEFORMABLE MODEL is employed to automatically track the vessel segment of interest, labeled by start point and end point selected by operator. The model deforms from its initial position, which is the line connecting start and end point, until stops at the real location of the target feature. Measurements of intensity similarity on end points and displacement similarity on middle points are introduced into the external energy to avoid model shrinking and shifting along the object during deforming. A rediscretization process is carried out after each deformation to ensure the continuity and smoothness of the model with an effect of decreasing the sensitivity to weighting parameters. The method is tested on several clinical ANGIOGRAM sequences and results are presented.
