Quantitative evaluation of respiratory motion estimation. The mean × (left–right; LR), y (anterior–posterior; AP), and z (superior-inferior; SI) components of respiratory motion estimated by fNAV measured in four regions of interest are shown for all 500 simulated data sets (ad), all 22 healthy subject data sets (eh) and all 549 cardiac patient data sets (il). Motion estimates derived from fNAV are compared to ground truth, and estimates derived from image registration for simulated and in vivo data, respectively. The results of a linear fit for each component is denoted by dash lines with the corresponding slopes and Pearson correlation coefficients given by [Sx, Sy, Sz] and [Rx, Ry, Rz] respectively
