Figure 9 : 

3D wall tracking in a patient with operated tetralogy of Fallot. In this example, a 3D volumetric dataset has been obtained incorporating the entire right ventricle. The 3D speckle-tracking algorithm follows speckles through the volumetric dataset. The colour coding represents 3D strain. The four-chamber, sagittal and short-axis cuts demonstrated are user-defined. The 3D strain model is shown in the lower-right pane. RA: right atrium; RV: right ventricle.
