Abstract
The invention relates to a system for determining a radiation therapy plan for a radiation therapy system (), comprising a multi-leaf collimator. The radiation therapy plan determination system () comprises a therapy system characteristics providing unit (), wherein the characteristics comprise possible leaf positions and possible radiation fluence values, a planning objectives providing unit (), wherein the planning objectives are indicative of a desired therapeutic radiation dose distribution, an optimization function providing unit (), wherein the optimization function is indicative of a deviation of a radiation dose distribution from the planning objectives and of an uncertainty of the radiation dose distribution at edges of the possible apertures, and a therapy plan optimization unit () adapted to determine a sequence of possible apertures and possible radiation fluence values for which the optimization function is optimized. Thus, an optimal therapy plan can be provided for each individual patient.
