Abstract
A control circuit carries out various actions to facilitate speedy user interaction involving adjustments to radiation dosing that corresponds to a particular mixed radiation treatment plan. These actions can include remixing particular multi-criteria optimization radiation treatment plans.
Claims20
A method to facilitate shaping a radiation treatment dose comprising:
- by a control circuit:
- accessing a plurality of different radiation treatment plans for a particular patient;
- forming a mixed radiation treatment plan from the plurality of different radiation treatment plans;
- presenting on a display a plurality of dose volume histograms for the mixed radiation treatment plan, wherein at least one of the dose volume histograms depicts a first histogram that relates radiation dose to a target volume and another of the dose volume histograms depicts a second histogram that relates radiation dose to an organ at risk;
- presenting on the display an overlay of calculated radiation dose from the mixed radiation treatment plan on a treatment planning image volume;
- detecting a user's manipulation of one of the dose volume histograms, and in response thereto, modifying on the display at least one other of the dose volume histograms as a function of a mix of at least two of the plurality of different radiation treatment plans.
