Claim:
1. A method to facilitate optimizing a radiation-delivery treatment plan, comprising: by a control circuit: before delivering radiation treatment to a target volume in a patient using a resultant radiation-delivery treatment plan: accessing a set of rules that control a radiation-delivery treatment plan optimization process as a function of detected changes to a treatment condition; loading initial radiation-delivery treatment plan parameters for the target volume with respect to a least one predetermined treatment objective comprising a dose volume histogram objective for a not-yet developed radiation-delivery treatment plan; beginning optimization of a radiation-delivery treatment plan using the initial radiation-delivery treatment plan parameters; detecting a change with respect to a treatment condition; prior to concluding optimization of the radiation-delivery treatment plan, using the set of rules to automatically change the predetermined treatment objective in response to detecting the change with respect to the treatment condition to provide at least one changed treatment objective; using the set of rules to continue to optimize the radiation-delivery treatment plan using the at least one changed treatment objective to provide a resultant radiation-delivery treatment plan; detecting a predetermined state as regards the optimization of the radiation-delivery treatment plan; in response to detecting the predetermined state, automatically changing a size of the target volume and continuing to radiation-delivery treatment plan to provide a resultant radiation-delivery treatment plan; after providing the resultant radiation-delivery treatment plan; using the resultant radiation-delivery treatment plan to delivery the radiation treatment to the patient.
