摘要：The necessity of ultrasonic diagnosis tools increases every year. We propose an automatic endocardium tracing method that applies active contour models(ACM) in two stages. In the first stage, an endocardium contour is detected using the result of an edge extraction based on the separability of image features. In the second stage, the endocardium contour is extracted using shape correction processing. "Mitral valve processing" not only detects the position of the mitral valve at the end-diastolic period but also corrects the detected contour after the first stage of ACM. The result of experiments using one healthy and three diseased cases demonstrate the effectiveness of the proposed method.
