Patient 40, follow-up group. (a) Coronal ${\mathrm{RACT}}_{4\mathrm{D}\text{-}\mathrm{CT}}$. (b) Coronal gamma $\left(\gamma \right)$ distribution, ${\mathrm{RACT}}_{\text{cine}}$ vs ${\mathrm{RACT}}_{4\mathrm{D}\text{-}\mathrm{CT}}$. This was the only patient in the follow up group to have any points inside the PTV fail our criteria (1%). Note the regions of high γ at the inferior and superior regions of the tumor.
