Abstract
A method for generating a radiation treatment plan is provided where uncertainties in the definition of regions of interest are incorporated and utilized by a treatment planning system for optimizing a treatment plan.
Claims14
A method for generating a radiation treatment plan for a subject on the basis of an internal image of said subject, the method being executed in a computer and comprising the steps of:
- retrieving an image of a subject;
- retrieving at least one uncertainty measure related to a region of interest in the image, wherein said at least one uncertainty measure reflects a degree of uncertainty regarding the definition of said region of interest;
- generating a plurality of different treatment plans, wherein a first subset of the different treatment plans is generated assuming said region of interest or part of said region of interest is not treated and a second subset of the different treatment plans is generated assuming said region of interest or part of said region of interest is treated;
- and
- generating the radiation treatment plan at least partly on the basis of said at least one uncertainty measure, and whereby the step of generating the radiation treatment plan comprises determining whether or not to treat said region of interest, or part of said region of interest, on the basis of the first subset and the second subset of the different treatment plans.
