Overall differences in DVH parameters across the test cohort were small. Mean DVH parameters were: Brainstem Dmax 4168cGy/4132cGy (for human/AI angles), Chiasm Dmax 1785cGy/1815cGy, left Optic Nerve Dmax 1457cGy/1492cGy, right Optic Nerve Dmax 695cGy/714cGy, left Cochlea Dmean 1167cGy/1254cGy, right Cochlea Dmean 388cGy/480cGy. None of these differences were significant. Average Body V30%, V50%, and V80% parameters significantly increased from 422cc to 482cc, 278cc to 290cc, and 176cc to 178cc, respectively for the AI chosen beam angles.

Conclusion:
