Overlapping Coronary Vessels in Angiography- A Review

Abstract

coronary heart disease remains affects millions of people around the world. X-Ray angiography imaging is a vital tool in assisting cardiologist for real-time visual analysis of coronary artery vessels to diagnose coronary artery disease. However, this tool only able to give cardiologist with less information because its 2D output and may suffer from overlapping coronary artery. Overlapping of the coronary artery vessel in the X-Ray angiography image is one of the issues can affect the result of segmentation angiography image and reconstruction techniques. Many publications might be found in the literature that presents the problem of overlapping coronary artery vessel in the X-Ray angiography image. However, to the best of our knowledge, there is not any review or survey confirmation of this problem in one paper. In this paper, we survey those papers that mention the overlapping coronary artery’s problem in X-Ray angiography image collected from C-arm, with respect to the purpose of usage of the X-Ray angiography image. Coronary artery segmentation is the process of extract vessels from 2D angiography image but the output of this process also have difficulty to overcome the problem of overlapping coronary artery vessel in the X-Ray angiography image. Therefore, it is becoming more important to propose an algorithm that can accurately separate overlapping vessels segments.
