  • the scanning stage 46 is arranged essentially parallel or slightly inclined to the wall on which the scanner 10 is suspended. This ensures a particularly flat design of the scanner 10, with a device depth of less than 30 cm being achieved.
  • the image information is preferably read out line by line, with a movable scan head being moved over the image carrier 44 lying on the scanning stage 46 in the scanner 10 or the image carrier 44 being moved past a stationary scan head.
  • the latter is preferably carried out during the removal of the image carrier 44 from the cassette 13 or its return to the cassette 13.
  • the corresponding stationary scan head is arranged in the area of the opening 18 inside the scanner 10.
  • the scan head has a line-shaped light source for illuminating a line-shaped region of the image carrier and a line-shaped detector for spatially resolved detection of the emission light excited in the illuminated region of the image carrier.
  • Light sources are preferably light-emitting diodes or laser diodes which are arranged along a row in such a way that their light beams overlap in such a way that a line-shaped area on the image carrier is illuminated with a substantially constant intensity.
  • a linear array of photodiodes or charge-coupled devices (CCDs) is preferably used as the spatially resolving detector.
  • a scan head constructed in this way permits image information to be read out line by line and thus quickly from the image carrier and is also very compact, so that this results in a very shallow device depth for the scanner 10 and thus for the entire device for carrying out a digital radiography method ,
  • the scan head and image carrier are continuously moved relative to one another with a suitable transport mechanism and successively read out line by line of the image information of the image carrier, data of an overall image of the image information stored in the image carrier are finally obtained.
  • The, in particular digital, data can then be processed, displayed and / or stored in a central processing unit, in particular in the workstation device 20.
  • a corresponding transport mechanism for moving the scan head over the image carrier preferably comprises a linear drive, in which the rotational movement of a drive motor is converted into a linear movement of a cable drive, by means of which the scan head is moved.
  • the scan head is preferably guided on the scan stage 46 itself, wherein the scan stage can have corresponding separate guide surfaces on which the scan head is guided. In this way, particularly small distance and position tolerances are achieved with a compact structure of the transport mechanism.
  • a compact and reliable mechanism for moving the image carrier past the stationary scan head is, for example, a gripper arm arranged in the scanner 10, which is suitable for pulling the image carrier out of the cassette and for pushing the image carrier into the cassette and thereby continuously moving the image carrier past the scan head, so that a successive line-by-line reading of the image information can take place.
  • the image carrier has suitable contours, in particular cutouts in which the gripping arm can engage.
  • an erasing device (not shown), in particular an erasing lamp, can also be provided, with the aid of which the image information of the image carrier is erased after the reading process, so that the image carrier can be used for a new X-ray exposure.
  • the erasing device can be attached and controlled in the scanner 10 in such a way that the image information remaining in the image carrier after reading out is completely erased while the image carrier is being returned to the cassette. This is achieved, for example, by arranging the erasing device in the region of the opening 18 of the scanner 10 and switching on the erasing device during the return of the image carrier.
  • the erasing device can be attached to the scan head and can be moved with it over the image carrier.
  • the light emanating from the extinguishing lamp can be adapted using suitable optical means, such as e.g. B. mirrors and / or light-scattering means, so distributed in the interior of the scanner 10 that deleting the entire surface of the image carrier is possible at once.
  • suitable optical means such as e.g. B. mirrors and / or light-scattering means, so distributed in the interior of the scanner 10 that deleting the entire surface of the image carrier is possible at once.
  • the extinguishing lamp is briefly switched on and off again at the given time.
  • FIG. 6 shows an enlarged schematic front view of a hard copy device 26, the statements relating to FIG. 1 correspondingly applying.
  • the hard copy device 26 can also have configurations 48 for suspension which are used for wall mounting.
  • height adjustability can be achieved by appropriately modifying the configurations 48 and / or the corresponding fastening elements on the wall and / or by means of a suspension device of this type.
  • both components or only the scanner can have corresponding configurations for suspension, since the components can be coupled such that the hard copy device 26 is held by the scanner 10 during wall mounting.
  • the hardcopy device 26 is shown partly in cross section mounted on a wall.
  • the hard copy blanks 50 can be stored inside the hard copy device 26 almost parallel to the largest side surface of the hard copy device 26 and thus also parallel to the wall and that they can be positioned along a likewise parallel or slightly inclined print plane.
  • the hard copy blanks or the hard copies can also be transported essentially parallel to a largest side surface of the hard copy device 26 and thus also parallel to the wall on which the hard copy device 26 is suspended. In this way, the device depth of the hardcopy device 26 can be minimized to less than 30 cm.
  • the individual components are wall-mounted, i. H. the scanner 10 and / or the workstation device 20 and / or the hard copy device 26, preferably hanging.
  • a wall mounting of the respective component can be carried out in any type of attachment to a wall in which no floor space is required for the respective component on the floor.
  • the respective component is essentially only attached to the wall.
  • the attachment to the wall can be done directly, for. B. by hanging, screwing and the like, or indirectly, e.g. B. by setting up or inserting the component on or in a wall-mounted bracket or by attaching to a wall-mounted and designed to adjust the height of the mounting system.
  • the wall mounting of the compact device according to the invention allows integration of this device in an X-ray room in many cases, although the available space there is usually limited by the high shielding effort.
  • the integration of the device in the X-ray room leads to considerable advantages in the workflow of an X-ray examination, since this enables the recording quality to be checked quickly in the form of a representation of the acquired image data on a screen and / or a hard copy and to leave the X-ray room or the patients in this room for diagnosis based on the x-ray is no longer required.
  • the suspension within the X-ray room can take place in particular where a conventional fluorescent screen was previously attached in order to view an X-ray film.
