3D Surface Reconstruction of Coronary Arteries

Dynamic variations of coronary arterial curvilinearity have been very difficult to study in the current 2D format. 3D models of coronary arteries are a robust help for scientific studies, diagnostic of the possible diseases, and surgery planning. Biplane angiography was the way to get 3D models since it is easier to reconstruct them using two views but it also suffers from the higher cost of these devices. This invention is a way to reconstruct a 3D coronary artery tree using single-view cineangiogram. Each single view can be used to construct a 3D robust model of the coronary artery from that angle of view. The developed approach consists of three stages where the first stage was the vessel extraction and labeling for each view for the purposes of constructing the 3D model. Meanwhile in second stage, the vessels information will be saved in data files to be used in the next stage. Finally, the last stage of this approach, we transformed the x, y, and z values to 3D shape. Results showed that our invention has high robustness to variety of image resolution and voxel anisotropy. From this result we can conclude that our invention is robust, simple and helpful tool in surgery Management. Work by Mr Hasan, as his PhD research work. (sigcasc.blogspot.com)
