Abstract
A process for an intensity-modulated proton therapy of a predetermined volume within an object includes discretising the predetermined volume into a number of iso-energy layers each corresponding to a determined energy of the proton beam. A final target dose distribution is determined for each iso-energy layer. The final target dose distribution or at least a predetermined part of this final target dose distribution is applied by parallel beam scanning by controlling the respective beam sweepers, thereby scanning one iso-energy layer after the other using an intensity-modulated proton beam while scanning a predetermined iso-energy layer.
