Claim 1:
2. The computer implemented method of claim 1, wherein training the one or more does predictions models based on the selected information including the nominal values of the parameters of the plurality of treatment plans and the perturbations of the nominal values 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 dose distribution based on the nominal values of each of the sub-volumes;
determining dose distributions based on the perturbations of the nominal values for each said sub-volumes;
generating a dose prediction model based on the nominal values for each of the sub-volumes; and
generating dose prediction models based on the perturbations of the nominal values for each said sub-volumes.
