Estimating the Myocardiums Angle of Three-Dimensional Trajectory Using the Tracking of Sequential Two-Dimensional Echocardiography Images

摘要

BackgroundIn this study, the angle of the myocardium's trajectory in three dimensions (ф) was estimated by simultaneous use of long-axis and short-axis views of left ventricle septum two-dimensional images. Then correlation of three-dimensional trajectory's angle with the rotation angle from the long (χ) and short (θ) axis views was estimated and compared at the three levels of base, mid and apex of the interventricular septum wall.
