1. A computer readable medium storing computer readable instructions which, when executed on a computer, cause the computer to perform a method comprising:

  • retrieving an image (12) of a subject (11), the image (12) comprising at least one region of interest;

    retrieving at least one uncertainty measure related to a region of interest in the image, characterized in that the at least one uncertainty measure refers to an uncertainty about and reflects a degree of a location of a contour or partial contour of the region of interest or about a property of tissue within the region of interest; and

    generating a radiation treatment plan based at least in part on the at least one uncertainty metric, wherein the step of generating the radiation treatment plan includes determining whether to treat the region of interest or a portion of the region of interest,wherein the radiation treatment plan is generated based at least in part on;

    an uncertainty metric associated with a first region of interest, a first treatment objective or constraint defined in association with the first region of interest, and a second treatment objective or constraint that at least partially conflicts with the first treatment objective or constraint.
