Coronary artery segmentation in cardiac angiography images based on a hybrid approach

A reduction of the size of the coronary artery openings, estimated by the visual inspection of the X-ray images of the transient radio contrast distribution during conventional angiography, can be used to formulate predictions about clinical symptoms and dynamic reductions in coronary blood flowing. Even with introduction of new noninvasive imaging modalities such as Cardiac CT and MRI, coronary angiography remains the gold standard for detecting ischemic coronary disease.
