Deposition of a target dose distribution in a cyclically moving target area

摘要

The invention relates to a method for depositing a target dose distribution in a cyclically moving target area (102) by multiple irradiation with a grid point of a target grid approaching beam (105) in at least two passes, wherein in each of the passes halftone dots are approached in succession. It is characterized by the steps of: setting the maximum tolerated local deviation from the target dose distribution, desynchronizing the course of the irradiation and the cyclical movement of the target area (102), and splitting the irradiation of the target area into a sufficient number of passes so that local deviations from the target dose distribution at most correspond to the maximum tolerated deviation from the target dose distribution. Furthermore, the invention also relates to an irradiation device for carrying out such a method and to a method for determining the control parameters for this irradiation device.
