From: Biological impact of geometric uncertainties: what margin is needed for intra-hepatic tumors?
Effects of geometrical uncertainty on the patient with 4D planning. (a) & (b) display dose profiles (OAX is the off axis distance) of the static plan ("P") and with different geometric impact s("SM", "IM" &"G") in "Y" and "Z" directions, respectively. (c) & (d) display the DVH of the plans with and without different geometric uncertainties for targets with sufficient margins (CTV & CTVa) and without sufficient margins (CTVb & PTV).
