原始语种摘要: Abstract(#br)Coronary artery disease (CAD) is one of the most leading cause of death in the world recently. Although conventional coronary angiography (CCA) is still as a gold standard for diagnosis of CAD, coronary CT angiography (CTA) is widely used due to its non-invasion. Meanwhile, centerline extraction of the coronary arteries offers some essential information for the radiologists. However, their extractions are extremely difficult due to the CT imaging nature, such as strong motion artifacts, poor contrast injection timing and low contrast. In addition, as the data increases rapidly, manual extraction becomes impractical, a fully automatic extraction method is becoming more necessary. In this paper, we propose an automatic and efficient method to extract the vascular centerlines in...
