    摘要: The device relates to a method and a device (10) for determining an irradiation plan for a particle irradiation unit (20). In the method, a target volume (6) within a test object (14; 18) is irradiated with a particle beam (16) using the particle irradiation unit (20) according to the irradiation plan. The radiation plan is determined in order to apply the energy of the particle beam (16) according to a predetermined dose distribution in the target volume (6), the target volume (6) and the predetermined dose distribution being pre-set. When determining the irradiation plan, irradiation duration is also taken into account, the irradiation plan being determined such that the irradiation duration is as short as possible.

    摘要: The invention concerns a process for the deposition of an intended dose distribution in a cyclically moved target region moving cyclically (102) by means of multiple irradiations with a beam (105) approaching matrix points of a target matrix in at least two scannings, wherein in each of the scannings, matrix points are approached sequentially. It is characterized through the steps: establishing the maximal tolerance level for local deviation from the intended dose distribution, de-synchronizing the sequence of the irradiation and the cyclical motion of the target region (102), and partitioning the irradiation of the target region (102) in a sufficient number of scannings such that local deviations from the intended dose distribution correspond at most to the maximal tolerance level of deviation from the intended dose distribution. Furthermore, the invention also concerns an irradiation apparatus for executing a process of this type and a process for determining the control parameters for said irradiation apparatus.

    摘要: The invention relates to a particle therapy apparatus having an accelerator for generating a particle beam, a passive energy modulator comprising an absorber element, and a control entity. The control entity is designed to switch between an active adjustment of the energy in the accelerator and a passive energy modulation by the energy modulator, for the purpose of changing the energy of the particle beam from a high energy level to a low energy level in a step-by-step manner. In particular, this has the effect of shortening the dead times when changing between the energy levels.
