摘要: We present a method to determine the sequence of mitral annular lines in 2D + 1D precordial echocardiogram. We first use the optical flow technique a 2-means algorithm to determine a set of possible mitral annular points. A pair of mitral annular points could form the mitral annular line. The problem to determine the sequence of mitral annular lines in 2D + 1D echocardiogram is modeled as a problem to find the shortest path in a graph. The proposed method need very few user inputs. Experimental results show that we can find accurate mitral annular lines.
