Biplane angiography is a common procedure to assess heart disease, resulting in time-equivalent x-ray images from two views. Using computer vision techniques, the topological data of coronary vessels are extracted. From the 2D models and the known imaging geometry a 3D model can be reconstructed. The spatial visualization of a malformed vessel morphology improves therapy planning and verification for interventional and surgical purposes. Quantitative evaluation of complex vessel parameters like volumes and lengths allows an objective assessment even of diffuse coronary atherosclerotic diseases. Therefore volume elements with elliptic bases are generated approximating the vessel shape and diameter. To perform the spatial reconstruction as accurately as possible, the knowledge of the imaging geometry used for a specific image series is evident. Thus, we developed an analysis and approximation system, correcting distorted parameters and approximating missing ones.
