- W2364679050 abstract "Objective To develop a processing and analysis system of X-ray coronary artery angiography(CAG) images.Methods Based on Hessian matrix for the purpose of vessel enhancement,the mathematical morphology algorithm and canny operator were used to achieve automatic extraction of vascular boundary and skeleton.Further,a new method for vessel diameter measurement,based on sectional measurement and vessel parallel feature,was proposed for accurate measurement of important parameters such as vessel diameter,vascular stenosis degree,stenosis length,etc.Results Firstly,compared with the method of global measurement,the sectional measurement provided more accurate results and efficiency of the measurement of vessel diameter.Secondly,the measurement results of vascular diameter and stenosis degree were in agreement with the measurement results of clinicians.Conclusion The proposed method has good effectiveness and practicality,which is beneficial to clinical diagnosis and treatment of coronary heart disease." @default.
