Method and equipment for an x-ray apparatus

An apparatus for determining alignment of a light field and an X-ray field of an X-ray apparatus, said arrangement comprising

• an X-ray indicating element 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, and
• a scale arranged in association with the X-ray indicating element, wherein said element and scale are configured to allow placement on an exposure area for said light and X-ray fields such as to allow determination of where on the scale an edge of the light field and an edge of the X-ray field are positioned when said fields are directed onto said exposure area, wherein the apparatus comprises a digital camera arranged to generate an image of the scale and the X-ray indicating element when the X-ray indicating element emits light due to an exposure of said X-ray field.

Device for determining alignment of a light field and an X-ray field of an X-ray apparatus, said device comprising

• an X-ray indicating element 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, and
• a visible scale arranged in association with the X-ray indicating element such as to allow determination of where on the scale an edge of the light field and an edge of the X-ray field are positioned, wherein the device comprises a first and a second unit, wherein each of said units comprises a set of said X-ray indicating element and scale, and wherein said first and second units are rotatably connected to each other.
