Abstract:- In cardiac catheterization labs, x-ray angiography is used to visualize abnormal narrowings of the coronary arteries, i.e., stenoses. An often used technique to treat stenoses is stent implantation. This technique can only be performed successfully if the length of the stenotic lesion and the radius of the non-stenotic part of the narrowed vessel segment are known precisely. In clinical practice, the determination of these quantities is done directly based on angiographic images of the coronary arteries or based on a three dimensional reconstruction of the coronary arteries build up using (two) angiographic images. In this paper, a method is presented to build up a three dimensional reconstruction of the centerline of the coronary arteries using more than two angiographic images. This is a preparatory step to build a complete reconstruction of the arteries based on more than two images. The presented method is based on discrete dynamic curves. The validation is done using computer-generated phantom images.
