Claim 9:
10. The one or more computing device readable media storing the computing device executable instructions that when executed by the one or more processing units perform the method of claim 9, wherein training the one or more does predictions models based on the selected information including the perturbations of the nominal values of the parameters of the treatment plans comprises:
for each treatment field of the treatment plans, determining a field-specific planning target volume (fsPTV) based on the perturbations;
accessing information that delineates at least one clinical target volume (CTV) and information that delineates at least one organ-at-risk (OAR) volume, wherein each said OAR volume comprises at least one sub-volume that is delineated based on spatial relationships between each said OAR volume and the CTV and the fsPTV for said each treatment field;
determining a plurality of dose distributions based on the nominal values of the parameters of the treatment plans and the perturbations of the nominal values of the parameters of the treatment plans; and
generating a dose prediction model for each said sub-volume, the model trained using the plurality of dose distributions.
