Example case with 50 Gy prescription from group 2 for isodose and fluence comparison. (a) and (c) are from the auto-plan and (b) and (d) are from the final plan. (a-1) and (b-1) are axial view, (a-2) and (b-2) are coronal view, and (a-3) and (b-3) are sagittal view. (c-1) and (d-1) are medial tangential beam using 6 MV, (c-2) and (d-2) are medial tangential beams using 15 MV, (c-3) and (d-3) are lateral tangential beams using 6 MV, and (c-4) and (d-4) are lateral tangential beams using 15 MV.
