Abstract
The accuracies of systems for Quantitative Coronary Angiography, as well as for 3-D reconstruction from biplane angiograms, strongly depend on the quality of the used image data. To complete our highly accurate reconstruction system, we developed several methods for equalizing gray value contrasts to enhance vessel detection, and improved algorithms for elimination of geometric image distortions. Conventional rectification algorithms using a regular grid mostly neglect dynamic influences like the magnetic field of the earth, To avoid the necessity of determining the distortion for each possible angulation individually, we interpolate a specific rectification polynomial from two extrema.
