Abstract:
A panoramic dental X-raying method, comprising emitting a substantially constant intensity X-ray beam (12) from a radiation source (9) provided in a rotating arm (7), guiding said beam through the dental arch (1) to a recorder (11) disposed opposite the radiation source in the arm in order to form an image, rotating the arm so as to form an image of substantially the entire width of the dental arch, limiting the X-ray beam (12) by a shutter (13) in the front area of the dental arch (1) as compared to the two sides of the arch, in order to increase in said front area the thickness of the layer (4) of which a sharp image is formed, and retarding the movement of the X-ray beam (12) in said front area of the dental arch (1) compared to the two sides of the arch.
