A method comprising:
- automatically determining a beam parameter at each of a plurality of treatment nodes, wherein the beam parameter is a geometric primitive for a beam shape;
- and
- automatically calculating a dose distribution based on the beam parameter at each of the plurality of treatment nodes.
A method of generating a treatment plan for a radiation delivery treatment system comprising:
- at a node position, stacking together radiation beams at different orientations to match a target silhouette;
- automatically determining a beam parameter at the node position;
- and
- generating the treatment plan based on at least the beam parameter.
A system comprising:
- means for automatically determining a beam parameter at each of a plurality of treatment nodes, wherein the beam parameter is a geometric primitive for a beam shape;
- and
- means for automatically calculating a dose distribution based on the beam parameter at each of the plurality of treatment nodes.
A system for generating a treatment plan for a radiation delivery treatment system comprising:
- means for, at a node position, stacking together radiation beams at different orientations to match a target silhouette;
- means for automatically determining a beam parameter at the node position;
- and
- means for generating the treatment plan based on at least the beam parameter.
An apparatus comprising:
- a radiation beam treatment system to deliver a radiation beam to a treatment site using a collimator;
- and
- a radiation treatment planning system operatively coupled to the radiation beam treatment system, the radiation treatment planning system to determine a beam parameter at each of a plurality of treatment nodes, wherein the beam parameter is a geometric primitive for a beam shape of the collimator, and automatically calculate a dose distribution based on the beam parameter at each of the plurality of treatment nodes.
An apparatus for generating a treatment plan for a radiation delivery treatment system comprising:
