The invention relates to a method for determining a position of an object in a beam apparatus which has a processor unit and which is used for processing, imaging and/or analyzing an object. The method has the following steps: (i) providing firstly a predefinable region of an object and secondly a marking in the beam apparatus, wherein the predefinable region has a first position in relation to the marking, and wherein the first position is given by a first distance and a second distance; (ii) rotating the object or rotating a capture device of the beam apparatus; (iii) determining a further second distance; and (iv) determining a second position of the predefinable region of the object in relation to the marking using the first distance, the second distance and the further second distance.
