Summary of displacement magnitude (d) and components along $({\overrightarrow{\mathbf{n}}}_{\mathit{gv}}(d_{\text{gravity}})$ and $({\overrightarrow{\mathbf{n}}}_{\mathit{nml}}(d_{\text{normal}})$, parenchymal lateral shift (d_lateral), the angle between $({\overrightarrow{\mathbf{n}}}_{\mathit{gv}}$ and $({\overrightarrow{\mathbf{n}}}_{\mathit{nml}}$, as well as the corresponding total computation times. The average magnitude values of these metrics across the patient cases are also reported. Image pairs in parentheses (1st column) indicate the two acquisitions being evaluated, and the time between these image acquisitions, separation time (2nd column), is also given.
