Estimated adjusted mean tracking factor, from the linear mixed effects (random intercept and tracking factor) model, for the linear relationship between the RHD and LV displacements. The correlations between the estimated tracking factors using the projection navigators and associated real-time 2D images, and the pencil-beam navigators and associated real-time 2D images are also listed.
