DEPOSITION OF AN INTENDED DOSE DISTRIBUTION IN A CYCLICALLY MOVED TARGET AREA |
摘要 |
The invention relates to a method for depositing an intended dose distribution in a cyclically moved target area (102) by multiple irradiation with a beam (105) which approaches grid points of a target grid in at least two passes, in which grid points are approached in succession in each of the passes. It is characterized by the following steps: setting the maximum tolerated local deviation from the intended dose distribution, de-synchronizing the procedure of the irradiation and the cyclical movement of the target area (102), and dividing the irradiation of the target area into a sufficient number of passes such that local deviations from the intended dose distribution correspond to at most the maximum tolerated deviation from the intended target distribution. Furthermore, the invention also relates to an irradiation device for carrying out such a method and a method for determining the control parameters for this irradiation device. |
