    The specification relates to an apparatus for panoramic X-ray photography of the area of the dentition and the jaws, the apparatus comprising a frame part (1 ), a bearing part (2) linearly movable in relation to the frame part, and a support arm (10) attached with bearings rotatably to the bearing part, the arm having at one end an X-ray film (11) and at the opposite end a source of X-radiation (12). The movements of the bearing part (2), the support arm (10) and the film (11) are mutually synchronized in such a way that an image of an area of the desired shape, for example the shape of the patient's dental arch, is obtained on the film during the movement. It is the object of the invention to provide a possibility, without shifting the patient, to alter the enlargement coefficient and, as an additional effect, to provide the possibility of tilting the X-ray beam to the desired angle in relation to the horizontal plane, whereby it will be possible to photograph more sharply than previously, for example, teeth oblique in relation to the vertical level. In accordance with the invention, the support arm (10) is attached to the bearing part (2) by mediation of structural parts (9, 16) which are equipped with guides (22, 24) extending in the longitudinal direction of the support arm (10) and with transfer means (19, 20, 21), in such a way that the support arm (10), in other words the source of radiation (12) and the X-ray film (11), can be transferred in a direction parallel to the X-ray beam. Furthermore, the said structural parts (9, 16) have curved rails (13, 14) which work in conjunction with each other, the mutual movement of the rails affecting the tilt of the support arm. The adjustment movements are preferably effected by stepping motors.

    The invention relates to medical technology, in particular to X-ray diagnostic equipment.
    The purpose of the invention is to simplify the image scale without displacing the acient and ensuring adjustment of the spatial position of the beam of study.
    FIG. Figures 1 and 2 show the JQ device in the erased state.
    The device for radiography of the chyustnoy and dental area contains a staionary frame 1 mounted on a stand with a stand. On the CTa-jj stationary frame 1, a carrier unit 2 is disposed, having rails 3 by means of a stepper motor 4, the shaft of which is a screw 5, a part mated to which is fixed to the carrier unit 2. 20 A coupling 6 is connected to the carrier unit 2 through bearings rotation by means of a stepper motor 7 and a V-belt 8.
    A plate-25 element 9 mounted in the longitudinal guides 10 on the inner sides of the box-shaped unit 11 is fastened to the clutch 6 on the lower surface of the plate-like element 9 and the JQ 12 motor is attached to the inner side of the box-shaped unit 11. A support bracket 13 is mounted on the cusp node 11, at one end of which there is a movable X-ray film 14, and on the other end - an X-ray source 15 with means for limiting the beam. At least the middle part of the support bracket 13 is curved so that the center point of this curve, i.e. axis of inclination, located at the level of the patient's head. On the koroboobraznoe node 11 with bearings fixed rollers. 16, 17, which are in contact with the side and top and bottom surfaces of the arcuate section of the support bracket 13. With the box-shaped unit 11, the motor 19 is swiveled through the shaft 18 and the connecting piece 21 is mounted on the outer shaft 20 of which is 5 swiveled. the surface of the support bracket 13.
    The device works as follows.
    In the production of panoramic radiography, the support bracket 13 is rotated by means of the engine 7 around the ver 35

    tical axis. In order to obtain a clear image of the dental arch, the axis of rotation of the support bracket 13 together with the carrying unit 2 during the exposure of the X-ray film 14 is moved linearly and parallel to the axis of symmetry of the dental arch. In this case, the movements of the carrier unit 2, the support bracket 13 and the film 14 are synchronized in such a way that a clear image of the desired area is obtained on the film.
    If it is necessary to change the image scale, the support bracket 13 with the radiation source 15 and the X-ray film 14 is moved in a direction parallel to the x-ray plane by means of the engine 12, while moving the box-shaped unit 11 relative to the plate-shaped element 9.
    To obtain a clear image of the teeth deviating from the vertical plane, the support bracket 13 is inclined by moving it along the guide rollers 16, 17 by means of the engine 19. It is possible to limit the area of X-ray propagation in the vertical direction so as to obtain an image upper or lower teeth.
    With programmed control of stepper motors, several mutually synchronized adjustments can be made continuously during the exposure.
