Resumen
Rotational X-ray coronary angiography is a medical imaging technique safe and effective in identifying of the
luminal disease, which considers a significant reduction in radiation exposure and contrast medium volume
compared to conventional angiography. The main objective of this research is to propose a computational
approach to automatically extract a description of the morphopatological shape of the left coronary artery
by means the centerlines of this vessel. The proposal is based on a sequential design which involves image
enhancement, identification of all the types of vascular points belonging to the vascular system, construction
of the coronary tree and tracking of the centerlines along the rotational angiography sequence. Some results
obtained after applying this method to monoplane rotational X–ray image sequences are presented.
