A therapy planning system and method generate an optimal treatment plan accounting for changes in anatomy. Therapy is delivered to the subject according to a first auto-planned optimal treatment plan based on a first image of a subject. A second image of the subject is received after a period of time. The second image is registered with the first image to generate a deformation map accounting for physiological changes. The second image is segmented into regions of interest using the deformation map. A mapped delivered dose is computed for each region of interest using the dose delivery goals and the deformation map. The first treatment plan is merged with the segmented regions of the second image and the mapped delivered dose during optimization.

Automatic plan optimization for changing patient anatomy in the presence of mapped delivered dose from delivered fractions

A therapy planning system () and method generate an optimal treatment plan. A plurality of objectives are automatically formulated () based on a plurality of clinical goals including dose profiles and priorities. The dose profiles and the priorities correspond to a plurality of structures including a plurality of target and/or critical structures identified within a planning image. Further, a plurality of treatment plan parameters are optimized () based on the plurality of objectives to generate a treatment plan. The plurality of objectives are reformulated () and the plurality of treatment plan parameters are reoptimized () based on the reformulated plurality of objectives to generate a reoptimized treatment plan. The optimizing () is repeated based on the reformulated plurality of objectives to generate a reformulated treatment plan.
