    摘要： The invention relates to a system for planning a radiation therapy treatment, wherein radiation delivered to a region of a patient comprises a plurality of individually controllable radiation contributions. The system obtains a first treatment plan generated in accordance with values of parameters quantifying an amount of radiation provided by the radiation components and resulting in a first dose distribution in the region of the patient body, obtains an instruction to change a radiation dose delivered to at least one volume element, and directly calculates, for each of the radiation components, a change of the amount of radiation provided by the radiation component based on the instruction and based on the contribution of the radiation component to the radiation dose delivered to the at least one volume element. On the basis of the calculated changes, a second treatment plan is determined.

    摘要： The invention relates to the planning of a radiation therapy treatment of at least one structure in a region of a patient body. A planning unit obtains a first treatment plan generated on the basis of a planning image of the body region and on the basis of dose objectives. Moreover, the planning unit receives a further image of the body region of the patient body, determines a transformation for generating an adapted treatment plan from the first treatment plan and/or for generating an adapted dose distribution from the dose distribution corresponding to the first treatment plan on the basis of the further image and determines an adapted treatment plan on the basis of the transformation and/or the adapted dose distribution. In accordance with the invention, the transformation on the basis of the dose objectives

    摘要： The invention relates to a planning system 7 for planning a radiation therapy procedure, wherein the radiation therapy procedure includes rotating a radiation source 2, which is configured to emit a radiation beam 3 for treating a subject 4, along an arc around the subject, in order to apply the radiation beam to the subject in different treatment directions. A sequence of sub-arcs groups is provided, wherein a respective sub-arcs group comprises several sub-arcs of the arc, which are evenly distributed along the arc, wherein a treatment plan is generated by sequentially determining for each sub-arcs group treatment parameters, which define a property of the radiation beam, in the provided sequence. Determining the treatment parameters by using this sequence leads to an increased likelihood that really an optimal treatment plan is generated.
