Abstract

In view of the existing endocardium and epicardium contour of left ventricle segmentation methods, there are some problems such as the poor regularity of segmented contour, segmenting the fuzzy edge of ventricular membrane incompletely and low segmentation efficiency. This paper proposed a new double well potential function and anisotropy gradient vector flow(AGVF) energy function improved level set model, with the fusion of zero level set and k level set of the double level set, the division of left ventricular inner and outer membrane method at the same time. First of all, with the modified Hough change detection algorithm, positioned ventricular endocardium and epicardium initial position; then, it used the double level set model to segment the endocardium and epicardium simultaneously. The experimental results show that the proposed method can segment smooth endocardium and epicardium contour of left ventricle. The analysis of experimental datum demonstrates that the proposed method can segment endocardium and epicardium contour of left ventricle confirms to the clinical definition, and increases averagely the overlap rate of the endocardium and epicardium contour on MRI images to 0.956 9.
