Abstract :
Geometric measurement of localized lumen stenosis of the coronary artery is an important indicator of heart disease. Three-dimensional (3-D) reconstruction of coronary arteries is of significant interest for providing accurate quantification of coronary vasculature and stenosis information. The overall method of coronary arterial analysis, as presented here includes: segmentation of the coronary vessels followed by medial axes and diameter feature detection for the entire arterial tree; registration of the arterial trees from the two views; 3-D reconstruction from the two view medial axes and correction for any error in 3-D geometry (pose) to obtain final 3-D reconstruction. Measurements were made for performing an error analysis of a pig-cast phantom and human data, in order to evaluate the presented method
