1. A method for formulating patient treatment prescription instructions for radiation therapy, which patient treatment prescription instructions are configured for use to determine corresponding radiation treatment plan optimization objectives for creation of an optimized radiation treatment plan for a particular patient using a particular radiation treatment platform, wherein the patient treatment prescription instructions do not accommodate technical details and specifications of the particular radiation treatment platform, the method comprising:
providing a user interface;
presenting on the user interface a plurality of radiation-treatment prescription instructions that prescribe a particular radiation dosage for particular parts of the particular patient, wherein each of the radiation-treatment prescription instructions has an initial-state relative priority as compared to others of the plurality of radiation-treatment prescription instructions;
determining a pre-optimization first fluence-based radiation dose distribution for the particular patient as a function of the plurality of radiation-treatment prescription instructions and the initial-state relative priority for each of the plurality of radiation-treatment prescription instructions and presenting pre-optimization information regarding the pre-optimization first fluence-based radiation dose distribution for the particular patient;
automatically saving, as a corresponding first state, pre-optimization information regarding relative priorities amongst the plurality of radiation-treatment prescription instructions and the corresponding pre-optimization first fluence-based radiation dose distribution for the particular patient;
in response to a user changing, via the user interface, a relative priority for at least one of the plurality of radiation-treatment prescription instructions to thereby provide a changed relative priority amongst the plurality of radiation-treatment prescription instructions, dynamically determining a pre-optimization second fluence-based radiation dose distribution for the particular patient as a function of the plurality of radiation-treatment prescription instructions and the changed relative priority amongst the plurality of radiation-treatment prescription instructions and presenting pre-optimization information regarding the pre-optimization second fluence-based radiation dose distribution for the particular patient;
automatically saving, as a corresponding second state, pre-optimization information regarding the changed relative priority amongst the plurality of radiation-treatment prescription instructions and the corresponding pre-optimization second fluence-based radiation dose distribution for the particular patient;
displaying, on the user interface, visual information regarding changes to fluence-based dose distribution information that occur in response to changes to relative prioritization amongst the plurality of radiation-treatment prescription instructions to thereby illustrate, prior to optimizing a corresponding radiation treatment plan, dosing tradeoffs that correspond to prioritization amongst the radiation-treatment prescription instructions.
