Abstract
Systems and methods for proton therapy treatment planning can include a treatment planning system determining positions of a plurality of energy layers across a dimension of a planning target volume (PTV) along a proton field direction, such that each pair of consecutive energy layers are spaced by a distance that is proportional to a width of a Bragg peak corresponding to at least one energy layer of the pair of energy layers. The treatment planning system can generate a proton therapy plan for irradiating the PTV according to the sequence of energy layers.
Claims20
A treatment planning system comprising:
- one or more processors;
- and
- a non-transitory memory to store computer code instructions, the computer code instructions, when executed, cause the one or more processors to:
- determine positions of a sequence of energy layers across a dimension of a planning target volume (PTV) along a proton field direction, such that for each pair of consecutive energy layers of the sequence of energy layers, a distance between each pair of consecutive energy layers is proportional to a width of a Bragg peak corresponding to an energy layer of each pair of consecutive energy layers;
- and
- generate a proton therapy plan for irradiating the PTV according to the sequence of energy layers.
A method of proton therapy planning comprising:
- determining, by one or more processors, positions of a sequence of energy layers across a dimension of a planning target volume (PTV) along a proton field direction, such that for each pair of consecutive energy layers of the sequence of energy layers, a distance between each pair of consecutive energy layers is proportional to a width of a Bragg peak corresponding to an energy layer of each pair of consecutive energy layers;
- and
- generating, by the one or more processors, a proton therapy plan for irradiating the PTV according to the sequence of energy layers.
A non-transitory computer-readable medium including computer code instructions stored thereon, the computer code instructions, when executed, cause one or more processors to:
- determine positions of a sequence of energy layers across a dimension of a planning target volume (PTV) along a proton field direction, such that for each pair of consecutive energy layers of the sequence of energy layers) a distance between each pair of consecutive energy layers is proportional to a width of a Bragg peak corresponding to an energy layer of each pair of consecutive energy layers;
- and
- generate a proton therapy plan for irradiating the PTV according to the sequence of energy layers.
