Treatment planning process and irradiation planning device for particle therapy

The invention relates to a method for generating a radiation treatment plan for a target volume, comprising the steps of: - providing a modulation curve which modulation of particle numbers at target points which lie in the target volume in the beam direction behind the other characterized, - determining a current location of the target volume, - determining a plurality of current target points which covering the target volume in its current position, - assigning particle numbers to the current objective points using the modulation curve. Furthermore, the invention relates to a formed for performing the method irradiation planning device.
