5.System requirements
To operate VistaScan the following components
are required. These are not included with the
standard Delivery Contents supplied with
VistaScan. 5.1X-ray cassettes
EN
Extra-oral exposures require X-ray cassettes without reinforcing foil. These are available as accessories for most X-ray appliances. For X-ray
cassettes with reinforcing foil this must be
removed.
5.2Monitor
Monitors designed for digital x-ray processes
with a higher light intensity and broad contrast
range should be used. Strong room lighting, direct sunlight and reflections all serve to reduce
the diagnostic capabilities of the X-ray exposures. See also the accompanying system
documentation.
5.3Minimum system requirements

automatically deleted in the erasure unit. 9.Transport drum:
The transport drum contains the complete
transport mechanism, as well as the scanning
unit and the erasure unit.
10.Green LED:
VistaScan is Ready
11.Status LED:
The LEDs show whether an image plate can be
inserted for scanning.
Green LED:
•An image plate can be inserted.
•Prevent image data on the image plate from

1a.Image plate (extraoral):
The image plate serves as the exposure medium
for X-rays and stores the image data.
1a.Image plate (intraoral):
(as section 1a)
2.Light protection cover (Intraoral):
•Light protection covers protect the patient
from infection by contaminated image plates.
•Reduces the risk of damage to the image
plate in the patient's mouth. •The image plate is slid into the extraoral foil
cassette and then placed together into the
X-ray unit.
•The image plate together with the foil cassette
is positioned in the entry slot of the transport
drum and thus into the VistaScan.
4.Holder for foil cassettte
Foil cassettes not currently being used can be
placed in the special holder.
5.Wall mounting bracket:
The VistaScan Plus can be inserted into the wall
mounting bracket when not in use.
6.Foil cassette (Intraoral):
being erased.
LED blinks:
•No connection to PC.
•Memory full.
14.On / Off key:
Press the key for 2 seconds to switch off or on.
•The image plate together with the foil cassette
is positioned in the entry slot of the transport
drum and thus into the VistaScan.
6.a Foil cassette sizes:
The numbering, e.g. "2" denotes the size of the
image plate which must be used with a particular foil cassette.
6.b Lever:
The lever is used to slide the image plate out of
the foil cassette and into the VistaScan.
6.c Tab:
The tongue situated on the lever helps to push
the image plate from the foil cassette and into

8.Functional Description
image plate
The VistaScan is used to transfer the data present on an image plate into a digital exposure.
Photomultiplier
laser source
IIntraoral X-ray:
The intraoral image plate (1) is placed inside the
disinfected light protection cover (2), placed into
the patient's mouth and exposed.
After exposure the light protection cover is disinfected and the image plate is removed and slid
into a foil cassette (6) of the appropriate size.
EN Extraoral X-ray:
The extraoral image plate (1a) is placed into the
appropriate foil cassette (3). The foil cassette is
then inserted into the X-ray cassette, placed in
the X-ray appliance and exposed.
Scanning the image data
Pressing the on-off button (14) switches on the
VistaScan. Then the image data editing and the
archive software, e.g. DBSWIN from V 4, of the
scanning mode is activated. Finally the foil cassette (3 or 6) together with the
extraoral or Intraoral image plate is positioned at
the entry slot (12) of the transport drum (9) and,
when inserted fully, correctly aligned. When the LEDs (11) are green, then the image
plate can be inserted into the entry slot (12). For
extraoral formats this is carried out by carefully
pressing with one's thumb in the foil cassette
itself and for intraoral formats by pulling down
the lever (6b). 14

rotating disc
The image plate is then automatically drawn into
the transport drum by the transport mechanism. Within the transport drum the image plate is
passed through the scanning unit where the
image data is scanned and the data transmitted
to the PC. A window on the monitor shows the
progress of this procedure. If more than one
image plate is being scanned simultaneously
then this will take place at the same resolution. After the scanning procedure is completed the
image plate passes to the erasure unit (8). Image data still held on the image plate will be
erased. After all stages have been completed
the image plate falls into a collector tray (7). It
can now be extracted and prepared for the next
x-ray exposure.
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.
2007/04
Installation
Only suitably qualified personnel are
permitted to set up, to install or to
operate the appliance.
9.Transport and packing
•Check that the delivery contents are complete
and check for any signs of transport damage. EN
•Empty the packing completely and store in a
dry place. 1
•Do not expose the VistaScan to any strong
shocks which could damage the appliance.
•Only use the original packing cases for
shipping.
10.Carrying the VistaScan
Always carry the VistaScan by holding the housing by the rear side
(fig. 1).

14.Image plate
Image plates are toxic: For this reason they must always be placed in a light protection cover before putting this in the mouth of the patient. In the case of a patient
swallowing an image plate or a part of one then a doctor must be consulted immediately and the image plate removed.
If a patient damages a light protection cover when biting on it, then the mouth must
be rinsed out thoroughly with copious amounts of water.
EN
14.1General
inactive side:

21
Danger of infection!
Wear protective gloves when placing
image plates into the patient's mouth.
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 placed in the
mouth so that the symbol will not affect
the diagnostic usefulness of the X-ray
exposure. •Place the image plate inside the light protection cover as normal into the patient's mouth.
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 techniques which
will not cause damage to either the
light protection cover or the image
plate. Handling systems with sharp
edges should be avoided.
•Set exposure time and settings on the X-ray
appliance.
•Produce an X-ray exposure.
The image data present on the
image plate must be processed
and scanned within 30 minutes of

17.3Preparing to scan image data
Danger of infection!
Wear protective gloves when removing
image plates from the patient's mouth.
•Remove the image plate inside its light protection cover from the patient's mouth.
•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.
23
•Clean and disinfect the light protection cover
and the gloves with a disinfectant wipe (e.g. EN
Dürr FD 350).
Alternatively, use a disinfectant spray (e.g. Dürr FD 322, FD 333) on a soft, fluff-free cloth
instead of a disinfectant wipe.
•Lay the image plate down in the light protection cover in the disinfectant wipe. •Take off the protective gloves, disinfect the
hands (e.g. with Dürr HD 410) and clean (e.g. with Dürr HD 430, HD 435).
