A combined shape tracking and speckle tracking approach for 4D deformation analysis in echocardiography |

Quantitative analysis of left ventricular function provides valuable information about overall heart health. Echocardiography is non-invasive method for imaging the heart that provides high temporal resolution allowing for imaging cardiac motion. Shape tracking and speckle tracking are two methods that have previously been used to track cardiac deformation in ultrasound. These two methods provide complementary displacement values. Shape tracking gives accurate boundary displacements, while speckle tracking provides accurate displacements across the myocardium. We combine these two methods using adaptive multilevel radial basis functions on 4D echocardiography data. Radial strains were calculated for N=5 open chest canines 6 weeks post-coronary artery occlusion. Radial strain values for three myocardial segments across three short axis slices showed good correlation to corresponding MR tagged data. |
