摘要： A dental x-ray diagnostics installation for producing panorama tomograms of the jaw of a patient has a radiation source and a detector, which converts x-radiation into corresponding light radiation, disposed on opposite sides of the patient. The detector is preceded by a secondary diaphragm. The radiation source, the detector and the secondary diaphragm are rotated around the patient so that radiation attenuated by the jaw, and passing through the secondary diaphragm is incident on the detector. At least one CCD sensor is provided on which light radiation generated by the detector is incident. The CCD sensor converts the light radiation into electrical signals. The sensor has an image zone with a number of lines parallel to a longitudinal extent of the opening of the secondary diaphragm, and has a storage zone. The lines in combination receive all of the light radiation so as to generate a complete charge image corresponding to the x-radiation incident on the detector. A clock generator is provided which controls transfer of the charge from the lines of the image zone into the storage zone, and also controls read-out of the storage zone. By selecting the frequency of the clock pulses generated by the clock pulse generator, the transfer and read-out speed can be selected to simulate the speed of movement of x-ray film in a conventional dental panorama tomography apparatus.

摘要： In order to provide a dental X-ray diagnostic installation for producing panoramic tomograms of the jaw of the patient and to achieve a simple structure with improved image quality, the apparatus includes an adjustment mechanism for the carrier of the radiation source and the film cassette holder to be adjusted in an orbital curve corresponding to the dental arch of the patient. The adjustment arrangement includes first adjustment parts with which the carrier can be rotated around a first vertical axis, and second adjustment elements for moving or swivelling the first axis in an arch transverse relative to the symmetry axis of the subject during the rotary motion. The swivel radius and the amount of excursion of this swivel motion are selected so that the perpendicular transillumination direction through the subject gives a constant distance between the subject and the film during the motion of the rotary unit. To accomplish this, the invention includes two separate embodiments with various modifications.

摘要： A dental x-ray diagnostics installation has a rotary unit carrying an x-ray source and a radiation detector disposed behind a secondary diaphragm, the rotary unit rotating around the jaw of a patient to produce panorama tomograph exposures of the patient's jaw. The radiation detector generates electrical signals proportional to the incident radiation intensity. To simplify signal processing, the detector is formed of one or more semiconductor detectors having a scintillation layer which corresponds to the size of the opening in the secondary diaphragm. The voltages acquired by the detector are converted to digital form, and stored in an image memory. A computer calculates a total image from the signals supplied by the detector, and stored in the memory, during a complete exposure. The signals from the image memory are combined to generate a tomogram of a desired slice of the patient's jaw.

摘要： An apparatus for positioning the head of a patient for producing dental panorama tomograms, which apparatus has an arrangement for positioning the head in a desired position relative to a fixed point with respect to at least one projection plane and this point, in turn, assumes a definite position relative to a central ray extending from the x-ray tube towards the x-ray picture, characterized by an arrangement for producing silhouettes and for projecting the silhouettes of the head in an actual position and in a desired position, simultaneously with the fixed point of each of the two silhouettes coinciding. By moving the head forming the silhouette of the actual position, the silhouette of the actual position can be moved to be congruent with the silhouette of the desired position to bring the head into the desired position for x-ray exposure.
