Abstract
A method of evaluating the robustness of a radiotherapy treatment plan for ion based radiotherapy, comprises the steps of: obtaining information related to the incident energy of ions that will stop in each voxel of the treatment volume; calculating a quantity value representative of the incident energy of these ions; and using the quantity values calculated for the first and second portion as a measure of the quality of the radiotherapy treatment plan, in particular its robustness. The information may include the mean incident energy for all ions, and/or an indication of the distribution of the energy values for all the ions.
Claims13
A method of evaluating a radiotherapy treatment plan for ion based radiotherapy, comprising the steps, for each of at least a first and a second portion in a treatment volume, of:
- obtaining information related to the incident energy of ions that will stop in the portion;
- calculating a quantity value representative of the incident energy of the ions that will stop in the portion;
- and
- using the quantity values calculated for the first and second portion as a measure of the quality of the radiotherapy treatment plan, in particular its robustness.
