摘要: Efficient and robust identification of the left ventricular borders remains a challenging problem in cardiology. In this paper, we proposed an automatic method to segment the left ventricles and then identify their borders robustly. The proposed method is named as "ABDC" because it utilizes the strengths of four techniques: Automatic threshold selection; Boundary extraction, Deformation flow tracking, and Convex shape modeling. We compared the proposed method with the PDE optical flow method on 1660 images which are obtained from ten complete short-axis cine MRI datasets (five normal subjects and five patients). As it turned out, the proposed method is more efficient and robust than the benchmark in segmenting LV borders. Note to Practitioners-The proposed method is implemented in a user friendly interface software and can be easily used to identify the boundary of the ventricle automatically by practitioners. The boundary of the left ventricle in the first frame of the slice is identified automatically by level set method and then it could be improved if necessary by the practitioner to guarantee accurate input boundary. Then, the rest of the frames are segmented by the proposed method automatically. The automatically identified boundary can be further improved by the practitioners manually and interactively after all the borders are identified.
