3-D reconstruction of coronary arteries
Alok Sarwal, Atam Prakash Dhawan · 2002
Coronary arteriography is a technique used for evaluating the state of the coronary arteries. Matching of coronary arteries from multiple views is necessary for obtaining a 3-D (three dimensional) description of the arterial tree. Overlapping vessels and artifacts due to digital subtraction of the angiogram background make the matching process quite difficult. Simplex method based linear programming and relaxation based consistent labeling are applied to skeletons from three views in order to obtain a matching of branches between views. Results show low error for 3-D reconstruction, by overlapping its forward projection with the skeleton extracted from one view.>
