1. A method for a real-time related correction of a spatial position of a central beam of a radiation therapy device by changing positions of collimator elements of a collimator and/or a spatial position of a patient support table, comprising:
retrofitting the radiation therapy device with
separate control modules, and
separate adjustment devices connected to the separate control modules, at least one of the separate adjustment devices being added to the collimator or the patient support table;
controlling the positions of the collimator elements and/or the spatial position of the patient support table for further degrees of freedom of movements, carried out through functional connections of the separate control modules;
changing the positions of the collimator elements and/or the spatial position of the patient support table within the further degrees of freedom, carried out via the separate adjustment devices; and
calculating correction movements in an irradiation planning system outside the radiation therapy device and/or in at least one microcontroller of a control system of the radiation therapy device.
