A method for exact positioning of a patient for radiotherapy or radiosurgery comprising the following steps: a) pre-positioning the patient relative to a linear accelerator, b) producing at least one X-ray image of the patient or one of his/her body parts in the vicinity of the radiation treatment target, c) mapping the X-ray image, d) generating at least one reconstructed image from a three-dimensional set of patient scanning data corresponding to said X-ray image, especially isocentrically, e) superimposing the reconstructed image and the X-ray image, and detecting the positional error electronically or computer-controlled on the basis of specific landmarks in both images, and f) correcting the position of the patient on the basis of the detected positional error.
