3D Vessel Reconstruction from Biplane Angiograms using Snakes

In this paper, we propose a physics-based model to segment and reconstruct coronary vessels from biplane angiograms. We use the snake technique to model the vessel, the snake deforms in space to adjust its projections to the image data. In this way, segmentation and 3 0 reconstruction are unified into the same procedure assuring that only plausible vessel shapes will be detected. The method is general allowing to reconstruct the coronary tree from any angles and distances. The results are encouraging.
