  • Patent number: 7628537
    Abstract: A small dental X-ray apparatus has an X-ray emitter 3 fixed to a cantilever 2, which X-ray emitter 3 can be manually adjusted in space relatively to a basic position by means of the cantilever 2. Means 14, 16, 18 are provided for the acquisition of the position and alignment of said X-ray emitter (3) in space. The method serves to automatically detect deviation of an actual position in space from a target position in space, which deviation is indicated by signalling elements 25 and the operator is informed on the quality of the actual position and on the direction of a change in the actual position which may be required to acquire an improved position.

  • Publication number: 20010048733
    Abstract: In a method and computer program for checking an image reproduction device a test zone is included as a partial region of the displayed image. An image parameter is assigned to the test zone and a partial region of the test zone is altered with regard to the image parameter. An input by the user is detected upon identification of a difference in the image parameter between the partial region and the remaining test zone. The image parameter of the partial region is stored and it, or of a transformation thereof, is composed with a predetermined guide value for the image parameter.

  • Patent number: 6055292
    Abstract: In a method and an apparatus for producing X-ray tomograms of the jaw and skull of a patient, a detector arrangement having at least one x-ray detector is provided. The radiation-sensitive area of the detector is a sub-area of the total detector area required for the subject exposure. The image exposure ensues in a number of chronologically separate sections in which, following a first sub-exposure, the detector arrangement is displaced along the longitudinal axis and/or the transverse axis of the detector surface and the diaphragm aperture of the primary diaphragm associated with the x-ray source is simultaneously correspondingly adapted so that the position of the x-ray beam is shifted so that it still strikes the detector appropriately after the detector is displaced.

  • Patent number: 5828721
    Abstract: A radiation diagnostic installation includes a panorama scanner for tomographically scanning a subject with radiation and for generating electrical signals dependent on the radiation shadow of the subject. A signal processor includes a memory for storing the electrical signals during the tomographic scanning and a computer for calculating signals corresponding to a tomogram of the subject in a desired slice position. The computer determines the desired slice position from the calculation of individual slice positions and their evaluation, thereby enabling faster production of tomograms in a desired slice position.
