Abstract: A method for X-ray imaging of mouth with intra oral imaging, method comprising: placing at least one image sensor inside the mouth, radiating from outside of the mouth with X-ray source, receiving X-ray radiation to form at least two sets of image information representing at least two different spectrums of X-ray absorption to achieve a optimal image information for analysis.

Abstract: The invention relates to a method for localizing cross-sectional X-ray images (6) taken from a given part of the dental arch, said imaging being effected with a panoramic X-ray apparatus which is provided with a patient supporting mechanism (1) and software for imaging the jaw in the transverse direction. The method includes a step of imaging cross-sections (6) on the same film as a respective longitudinal image (5) of the dental arch, and the cross-sectional images (6) are exposed to include identifications (A, B, C) for the sections, said identifications being also exposed on the longitudinal image (5) in alignment with the cross-sections along which the images are taken.

Abstract: An apparatus for panoramic X-ray photography of the area of the dentition and the jaws, comprising a frame part, a bearing part linearly movable in relation to the frame part, and a support arm attached rotatably to the bearing part, the arm having at one end an X-ray film and at the opposite end an X-ray source. The movements of the bearing part, the support arm and the film are synchronized in such a way that an image of an area of desired shape, e.g. the patient's dental arch, is obtained on the film. The invention provides a possibility, without shifting the patient, of altering the enlargement and, additionally of tilting the X-ray beam a desired angle in relation to the horizontal, whereby e.g. teeth oblique in relation to the vertical can be photographed more sharply.

Abstract: An apparatus for panoramic X-ray photography of the area of the dentition and the jaws, comprising a frame part, a bearing part linearly movable in relation to the frame part, and a support arm attached rotatably to the bearing part, and having at one end an X-ray film and at the opposite end an X-ray source. The movements of the bearing part, the support arm and the film are synchronized in such a way that an image of an area of desired shape, e.g. the patient's dental arch, is obtained on the film. The invention provides the effect that the X-ray beam can be tilted to a desired angle in relation to the horizontal, whereby it is possible with greater sharpness to photograph, for example, teeth slanted in relation to the vertical. For this purpose, the support arm is tiltable about an axis perpendicular to its rotational axis so that, when this axis is vertical, the straight line connecting the source of radiation and the film is obligue to the horizontal.
