In a method for alignment of a graphic object on an overview image of a subject (in particular of a body part of a patient) shown on a display screen, a graphic object establishes parameters for a subsequent imaging of at least parts of the subject; and an input device allows positioning of the graphic object on the overview image; with characteristic data that describe a type and a position of at least one characteristic pattern in the overview image upon which the graphic object is aligned. Given a position of the graphic object on the screen that is predetermined by the input device, a check is made as to whether the graphic object is located in an alignment region of the characteristic pattern in which an automatic alignment of the graphic object relative to the characteristic pattern can be implemented. An automatic alignment of the graphic object to the characteristic pattern if the graphic object is located in this alignment region.
