3D positions of a particular voxel for 25 cine CT scans in a patient (shown in circles) as well as the interpolated 3D trajectory from PCA model output using two coefficients and eigenvectors. SI: superior–inferior; AP: anterior–posterior; LR: left–right. The average 3D error for this voxel is 0.4 mm.
