description A method for producing an X-ray projection image of a body region of a patient using a desired spatial location of a central ray, includes positioning a pointing element relative to the patient indicating a location of a pointing line and causing the location of the pointing line to coincide with the desired central ray location. A pointing line location and a central ray location currently set on an X-ray machine are recorded. A measure for deviation between the pointing line and the currently set central ray location is determined and used to set the desired central ray location. A medical apparatus includes an X-ray machine taking an X-ray projection image along a central ray, a pointing element indicating a pointing line, an acquisition unit detecting the pointing line location and the currently set central ray location, and a control and evaluation unit implementing software carrying out the method.
