Echocardiography is a non-invasive method for imaging the motion of the heart. Two methods that have been used for quantitative deformation analysis in echocardiography are shape tracking and speckle tracking. Shape tracking provides good displacement values on the boundaries of the myocardium, while speckle tracking provides more accurate tracking across the myocardium. Combining these two complementary sources of information can provide more accurate displacement values over the entire myocardium. These methods combine the two information sources using adaptive radial basis functions over multiple frames. Ultrasound data was acquired on three normal canines. Radial strain values were compared between the shape tracking, speckle tracking, and combined methods to show improvement when using both sources of information. Strain values were calculated from MR tagged data for comparison.Read More
