Worst case robustness comparison of SFUD, SFIB and IMPT/MFO plans. The left column (blue) represents SFUD, the middle (red), SFIB, and the right (green), IMPT plans. For target volumes, the cold plans are used to evaluate target coverage in terms of percentage of doses of D₉₅, D₉₈ and EUD relative to the prescription doses. For critical structures, the hot plans are used assess the tissue sparing. (A) and (B) for patient 1 (BS – brain stem, HC – hippocampus, OC – optical chiasm, PH – pituitary and hypothalamus, WB – whole brain); (C) and (D) for patient 2 (SC – spinal cord, LK – left kidney, RK – right kidney); (E) and (F) for patient 3 (BLD – bladder, RET – rectum, FH – femoral heads); and (G) and (H) for patient 4 (LNX- larynx, RS – right submandibular, RC – right cochlea, and MDB – mandible).
