| Abstract(in English) | It is important to evaluate the severity of coronary atherosclerosis in patients with coronary artery disease. A computerized quantitative method for measuring coronary artery stenosis has been developed not only as an objective index of coronary disease evaluation but also as a decision making factor for selecting therapeutic method and aftercare of patients. In this study, a new quantitative method for coronary stenosis from cineangio-graphic images using pattern filter processing is described. In this method, it is assumed that inside wall surface of coronary artery image with stenosis as a combination of convex and concave patterns with various shape and size. In detail, those patterns on the surface were divided into several structure elements using morphology processing, and the elements were used to get stenosis index to evaluate the severity of disease. In experiments, we defined the formula to calculate stenosis index from pattern spectrum series of the elements, and we confirmed the effectiveness of this method in blood vessel model images with and without stenosis. Furthermore, we applied this method to several coronary angiographic images. |
