1. A method for determining a range of particle radiation, the method comprising:
- defining a target volume to be irradiated, the target volume characterized by a plurality of voxels;
determining, without exposing the target volume to particle radiation, radiation-attenuating properties that are associated with individual voxels of the plurality of voxels by performing a medical imaging procedure;
deriving a first range datum of a first voxel and range datums of two adjacent voxels from the radiation-attenuating properties; and
changing the first range datum of the first voxel when the range datum of the first voxel differs from the range datums of the two adjacent voxels.

Abstract
A method for determining a range of radiation is provided. The method includes defining a target volume to be irradiated using a plurality of voxels; determining, without exposing the target volume to radiation, radiation-attenuating properties that are associated with individual voxels of the plurality of voxels; deriving a range datum from the radiation-attenuating properties; and changing the range datum of a first voxel if the range datum of the first voxel differs from the range datum of two adjacent voxels.
