Example of semi-automated delineation of the right ventricle without manual correction. The semi-automated delineation crosses, and hence includes, parts of the septum in the right ventricular volume. On the other hand, the delineation does not follow the anterior part of the right ventricular outflow tract and that part is therefore by default not included in automated volume calculation. Data was processed with dedicated software (4D RV-Function, TomTec Imaging Systems). View Video 3 at http://movie-usa.glencoesoftware.com/video/10.1530/ERP-14-0077/video-3.
