Abstract
Placement of dose vertices in a dose lattice for lattice radiation treatment (LRT) is automated using a series of dose vertex constraints and objectives. The dose vertex constraints place limitations on the spacing and other spatial arrangement of dose vertices in the dose lattice, relative to other dose vertices, tumor volume, and/or organs-at-risk. The dose vertex objectives give preference to spatial arrangements of dose vertices in the dose lattice, such as having more centrally located dose vertices.
Claims18
A method for generating a radiation treatment plan for a spatially fractionated radiation treatment, comprising:
- accessing medical imaging data of a subject with a computer system;
- accessing dose vertex constraint data with the computer system, the dose vertex constraint data comprising spatial constraints on potential dose vertex locations;
- accessing dose vertex objective data with the computer system, the dose vertex objective data comprising spatial preferences on potential dose vertex locations;
- selecting a tumor region depicted in the medical imaging data using the computer system;
- constructing a dose distribution with the computer system by generating and arranging dose vertices in the tumor region subject to the dose vertex constraint data and the dose vertex objective data;
- and
- storing the dose distribution, by the computer system, in a radiation treatment plan for the subject.
