Determine the positioning settings of a medical imaging system

Method for determining the position settings of a medical imaging system (100), comprising having an around an isocenter (126) rotatable radiological therapy and / or inspection apparatus (120) comprises a radiation generating unit (122) and a detector unit (124) and which translational movements of a A patient support device (110) relative to the isocenter (126) allowed, characterized by the following steps: - acquiring first position information of the patient support device (110) and a first rotation angle of the radiological device (120), in which a subject to be examined or to be treated organ (140) of a patient (130) by means of appropriate positioning of the patient support device (110) by a handler in the center of the image (128) of the radiographic apparatus (120); - acquiring a second position data of the patient support device (110) at a second rotation angle of the radiological device (120), in which the body (140) also by means of corresponding positioning of the patient support device (110) by the dentist in the center of the image (128) of the radiographic apparatus (120 ) is; and - calculating the position settings of the system (100) from the first and second position data and the first rotation angle and / or the second rotation angle such that the member (140) on the positioning means of the calculated positioning adjustments at the isocenter (126) is located.
