Examples of the multi-field optimized plan (MFO-PTV, left) and the robust-optimized MFO (MFO-RO, right) plan on the (a) original computed tomography (CT) scans and on the (b) verification CT scans. Note that owing to the anatomy changes, the prescription line was broken, and dose to the esophagus and the spinal cord was elevated on the repeated CT scan for the MFO-PTV plan (b, left), but the dose was maintained on the repeated CT scan for the MFO-RO plan (b, right).
