摘要:
A radiodiagnostic apparatus including a pivotable table made up from a panel for supporting a patient and a tomography device articulated on a pendulum system, the assembly being mounted on a vertical ring-shaped support rotatable about its own axis. The tomography system and the patent supporting panel are suspended substantially at their centers of gravity on carriages sliding along two parallel circular arc-shaped arms perpendicular to the vertical ring. A system for coordinating the movements of the different mobile components of the apparatus makes it possible to pivot the tomography system about the axis of the patient supporting panel, which remains stationary in space.
摘要:
A system for processing photographic or radiographic film which has sensible zones coded with information concerning film-speed (sensitivity), type or quality. Coded information concerning format and size could also be provided. This coded information is encoded prior to the exposure of the film and capable of being decoded at any time. The encoding consists of transverse zones of altered transmissivity and/or reflectivity with respect to radiation which is emitted by sources located opposite one surface of the film and which is detected by appropriate detector-cells located opposite the other surface of the film. Alternatively, the zones may themselves be sources of radiation or of fields, e.g. magnetic fields. In all cases, the radiations and/or fields are non-actinic with respect to the photographic or radiographic emulsion, i.e. they do not cause physical or chemical changes in the emulsion. The motion of the zones past the detector-cells results in the emission of electrical signals which are decoded and used in activating mechanical or other control devices for developing and formatting the film and may also be used for inventory control.
摘要:
A film changer for X-ray diagnostic apparatus using bare film precut into sheets comprising three compartments, the middle one whereof making up the exposure and transfer section and the two lateral ones, containing two identical motor-driven electrically controlled magazines which are respectively and alternately used as a supply of unexposed film sheets and as a storage device for exposed undevelopped negatives.
