1. A dental or medical X-ray imaging arrangement, comprising:
an X-ray detector;
an X-ray source configured to generate X-ray irradiation and comprising a collimator functionally connected to the X-ray source, the collimator configured to limit the X-ray irradiation generated by the X-ray source into a beam to be aimed in the direction of the X-ray detector and defining an X-ray irradiation field pattern;
a light field indicator comprising a visible light emitting construction and configured to project a visible light field pattern to be aimed in the direction of the X-ray detector;
a support to which the X-ray source and the visible light emitting construction are each moveably mounted;
a control system, the control system comprising control information relating to an imaging mode;
characterized in that the support is configured to enable positioning the X-ray source and the visible light emitting construction at essentially the same location in relation to the support, so as to when at a given time locating at said essentially same location to direct a given irradiation/light field pattern in essentially the same direction towards the X-ray detector.
