1. A computer system, comprising:
a processor; and
memory coupled to the processor and including instructions that, when executed, cause the processor to
access information associated with a radiation treatment plan,
access information corresponding to an uncertainty associated with implementation of the radiation treatment plan,
perform an optimization process including generating a graphical element, wherein the graphical element conveys results of the optimization process including an impact of the uncertainty, wherein
the graphical element includes a band and one or more threshold curves, and
the one or more threshold curves correspond to at least one of a limit on dose, dose rate, or incidental radiation on healthy tissue, and
adjust the radiation treatment plan in response to the band including the one or more threshold curves.
