Definitions

  • the invention refers to a portable device which has the ability to hold the various sizes of radiographi cassettes during radiological examinations.
  • a specially chosen scatter grid has been placed on the portable system that is set in motion by means of a driving mechanism during the X-ray exposure.
  • the X-ray beam that is produced by a diagnostic unit transverses through the patient and then falls on the radiographic film forming a latent image. This image appears on the film after a process of development using special chemicals. A certain amount of the radiation produced by the X-ray tube will be absorbed and
  • the useful diagnostic image on the radiographic film is the one that is created by the attenuation of the primary beam.
  • Scatter is reduced by placing a movable scatter grid between the film and the patient. This grid absorbs scatter before falling on the film. In order to diminish scatter, the grid must move in a special way during the x-Ray exposure.

Abstract

L'invention concerne un système portatif qui permet de réaliser des radiographies avec une unité à rayons X mobile, en dehors des chambres de radiologie et sans que des radiations dispersées n'atteignent le film. Le dispositif réussit à diminuer la dispersion grâce à un mécanisme portatif qui déplace la grille durant l'examen radiologique. Des radiographies de haute qualité sont produites de cette manière.
