Abstract
Disclosed herein are methods (200) and systems (100) using artificial intelligence models (420) to control the amount of modulation in radiotherapy plans (440). The system (100) may receive (210) parameters defining a plan objective for a radiotherapy treatment plan (440). The system (100) may establish (220) dose distribution parameters for each field of the plan objective. The system (100) may initialize (230) user-defined field regularization factors for each field of the plan objective. The system (100) may initialize (240) plan regularization factors. In response to applying the user-defined field regularization factor to a corresponding field of the plan objective and the plan regularization factor to the plan objective, the system (100) may generate (250) a treatment plan objective incorporating weighted components for the plan objective and each field. The system (100) may transmit (260) the treatment plan objective to a radiotherapy treatment planning computer model. The radiotherapy treatment planning computer model may determine the radiotherapy treatment plan (440) based on the treatment plan objective.
