A DVH for hippocampal‐sparing WBRT using IMAT planning (Patient # III). A dose of 30 Gy in 10 fractions was prescribed to achieve better than 90% of the WB‐PTV coverage. In this case, maximum dose to WB‐PTV, D2%, D98%, and ${\mathrm{D}}_{\text{median}}$ was 34.8 Gy, 33.2 Gy, 26.1 Gy, and 31.7 Gy, respectively. Maximum and $\mathrm{D}100\%$ dose to hippocampus were $<16 \text{Gy}$ and $<9 \text{Gy}$, respectively. Optic pathway and brainstem doses were all well below RTOG 0933 guidelines.
