Abrégé

The invention concerns a method for determining alignment of a light field (13) and an X-ray field (12) of an X-ray apparatus (30), comprising the steps of: directing the light field (13) onto an exposure area (16), positioning a scale (6) and an X-ray indicating element (3) in association with each other at the exposure area (16) such that said scale (6) and X-ray indicating element (3) cross an edge (130) of the light field (13), wherein said X-ray indicating element (3) is configured to emit light upon exposure to X-rays in such a way that parts exposed to X-rays can be distinguished from non-exposed parts, determining a position on the scale (6) where the light field edge (130) is positioned, and directing the X-ray field (12) onto the exposure area (16). The invention is characterized in that the method comprises the steps of: generating an image of the scale (6) and the X-ray indicating element (6) when the X-ray indicating element (3) emits light due to the exposure of said X-ray field (12) using a digital camera (20), determining a position on the scale (6) where an edge (120) of the X-ray field (12) is positioned by analyzing said image, and comparing the scale positions of the edges (120, 130) of the light and X-ray fields (13, 12). The invention also concerns an arrangement for carrying out the above method, the invention also concerns a device that can be used in the arrangement.
