Patent ID: 8319198

Claim:
Device for determining control parameters for an irradiation system by means of which a number of irradiation doses are successively deposited at different target points in a target volume, comprising: an input device which is designed for detecting a target region and for detecting a movement of the target region, an evaluation device for detecting control parameters for controlling a beam of the irradiation system in such a way that with the help of the control parameters a beam is able to follow the movement of the target region and to deposit a defined dose distribution in the target region, wherein the evaluation device is designed in such a way that, for detecting the control parameters, at least a first selectable control parameter is detected so that the beam is able to follow the movement of the target region merely orthogonally to beam direction, or for detecting the control parameters, at least a first selectable control parameter and a further control parameter representing energy modulation of the beam are detected, wherein motion tracking in beam direction is taken into consideration.
