Finding the mitral annular lines from 2-D + 1-D precordial echocardiogram using graph-search technique.

Finding the mitral annular lines from 2-D + 1-D precordial echocardiogram using graph-search technique.

The apical four-chamber view echocardiogram collected by a transthoracic transducer can be used to evaluate the left ventricle volume. In the diastole, the left ventricle and left atrium become one chamber. In this case, the left ventricle and left atrium need to be separated using a "mitral an...
