Figure 5From: MRI-based treatment plan simulation and adaptation for ion radiotherapy using a classification-based approachCarbon ion plans of sample 2. (a) optimized on p CT and recalculated on r CT; (b) dose difference of (a) and (c); (c) optimized and calculated on r CT. The PTV size was 17 × 26 × 16mm3 and the unit of color scale is percent of the prescribed physical dose.Back to article page
