Abstract
A semi-automatic point-based 3D-2D registration approach to register computed tomography (CT) data with coronary angiograms using digitally reconstructed radiographs (DRR) is presented. It allows us to augment the coronary angiograms with pathologies (e.g. calcifications) found in CT data with an automated analysis tool that was previously developed in our department. We also present an efficient method to enable a backprojection from 2D into 3D space and to detect overlapping vessels. First qualitative results are presented.
