1. A computer system, comprising:
a processor; and
memory coupled to the processor and comprising instructions that, when executed, cause the processor to perform a method used for planning radiation treatment of a target volume in a patient, the method comprising:
accessing, from the memory, a first candidate radiation treatment plan comprising information describing a spatial distribution of radiation beams;
determining a distribution of dose in a volume of tissue that is outside of the target volume and intersected by the radiation beams;
determining a value of a metric that is a function of the distribution of the dose in the volume of the tissue; and
evaluating the first candidate radiation treatment plan using the value of the metric.
