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.

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.
An apparatus for determining a range of radiation, the apparatus comprising:
- a diagnostic device that is operable to obtain radiation-attenuating properties of a target volume;
- and
- a computation unit that is operable to derive a range datum from the radiation-attenuating properties of the target volume and change the range datum of a first voxel if the range datum of the first voxel differs from range datums of two adjacent voxels,
- wherein the first voxel and two adjacent voxels are voxels of the target volume.
