14 8. Functional description CR 7 VET transforms the intraoral image data stored on the image plate into a digital X-ray image. This image can then be viewed and edited using the connected PC system. Image plate Photomultiplier Laser source X-rays The image plate (1) is packed, disinfected and exposed inside the light protection cover (2). After exposure the light protection cover is again disinfected. Scanning the image data Pressing the On / Off key (5) will switch on the CR 7 VET. This activates the scanning mode using x-ray software, e.g. Vet-Exam Intra. Once the green status LED (6) is lit, the image plate in its prepared (opened) light protection cover can be placed centrally on the film feed tray (12). The image plate is now pushed carefully out of its secured and opened light protection cover into the film transport (11) using the fingers. The light protection cover stays in position at the film feed slot. As soon as the light protection cover is released, it can be removed. Parabolic mirror Reflection layer Rotating disc Pentaprism Further X-ray images After removing the image plates from the film collection tray it is recommended that they be repacked into a light protection cover. If used carefully it is possible to reuse the image plates several hundred times. Before reuse the image plates should be checked for signs of dirt or damage. Damaged image plates must not be reused. Once taken up by the film transport (11) the image plate is fed to the scanner unit. Here the image data on the image plate is scanned using a laser and the information transmitted to the PC. A window on the monitor shows the progress of this procedure. After scanning the image plate proceeds to the erasure unit, where any remaining image data is erased. Afterwards the image plate falls into the collection tray (10) / /09/06

23 16.2 X-ray exposure Danger of infection! Wear protective gloves when positioning the image plate. The image plates are marked with a symbol. The symbol is visible in the X-ray exposure, and makes orientation during diagnosis easier. The image plate should be positioned so that the symbol will not affect the diagnostic usefulness of the X-ray exposure. 12 Place the image plate inside the light protection cover as normal. The silver point on the inactive side must face the occlusal area. The active side of the image plate must point in the direction of the X-ray tube. Damage to the image plate Only use handling systems which will not cause any damage to either the light protection cover or the image plates. Handling systems which have sharp edges should be avoided where possible. Set exposure time and settings on the X-ray appliance. Taking the X-ray exposure. The image data present on the image plate must be processed and scanned within 30 minutes of exposure. 2013/09/ /30 23

24 Preparation for reading out the image data Danger of infection! Wear protective gloves when removing image plates. Remove the image plate in the light protection cover. If the light protection cover or the gloves are considerably dirty, e.g. from blood, then before disinfection the cover must be given a quick dry clean, e.g. by wiping with a clean piece of lint. Clean and disinfect the light protection cover and the gloves with a disinfectant wipe (e.g. Orochemie B60). Alternatively, use a disinfectant spray (e.g. Orochemie B30) on a soft, lint-free cloth. Lay the image plate down in the light protection cover in the disinfectant wipe. Damage to the CR 7 VET Before handling the image plates, hands should be completely clean and free of any traces of powder from protective gloves. This powder can damage the optical scanning unit of CR 7 VET during the scanning procedure of the image plate / /09/06

Select animal owner. Select measure for the animal. Activate the CR 7 VET in the software. Confusing patient X-rays The software ensures that the x-rays are always allotted to patients one after the other in the order of activated patients. In order to avoid confusing these X-rays from those of other patients only X-ray exposures for this (one) patient should be scanned at one time. 2013/09/ /30 25

26 Operational LED and status LED are both green: When the CR 7 VET is started from stand-by mode the green status LED blinks. Additionally, a progress bar will appear on the display. As soon as the appliance is ready for use, the status LED will show green. Open the light protection cover straight along the adhesive edge (V-cut). 15 Loss of image data Image data on the image plate will be lost when exposed to light. Never handle exposed image plates without the light protection cover. Place the light protection cover with its image plate centrally and parallel (opened side of the light protection cover should face down, inactive side of the image plate to face operator) onto the feed insert transport. The film grip mechanism automatically moves forwards and takes hold of the light protection cover with the image plate. Slide the image plate out of its light protection cover downwards into the appliance until the image plate is automatically taken up by the transport. The light protection cover is held by the grip mechanism and is not taken up by the appliance. Scanner progress can be monitored on a small inner window on the PC screen / /09/06

27 17 Status LED is yellow: Do not feed any more image plates. Once the scanning process has been completed the grip mechanism automatically returns to start. Remove the empty light protection cover. Status LED changes from yellow to green. Save the X-ray image in Vet-Exam Intra. Either insert a new image plate for scanning or turn off the appliance at the On/Off switch. When the On/Off switch is pressed for 3 seconds then the appliance shuts down. This can take a few moments (green and blue LEDs blink alternately and the display will show a progress bar). The appliance will shut down completely. Do not move the appliance during this phase. When the CR 7 VET is switched off, it can be covered and protected using the protective cover. 2013/09/ /30 27

28 16.5 Erasing the image data After scanning, the image plate automatically runs through the erasure unit. Image data still held on the image plate will be erased. Afterwards the image plate falls into the collection tray. Special mode "Erase" The image plate must be erased again if: the image plate has been stored and not used for longer than 24 hours. The image data on the image plate were not erased due to a fault in the CR 7 VET. (Error message from software) 18 The special mode enables the erasure unit in CR 7 VET to be activated alone. No image data will be transmitted to the software. To erase again: Choose the special mode "Erase" in the software. Place the open light protection cover with its image plate in the insert slot. Slide the image plate out of its light protection cover downwards into the appliance until the image plate is automatically taken up by the transport / /09/06
