2 Basic use
Process imaging plate(s) in the unit before packing and
exposure if:
• Using a new imaging plate for the very first time
• Imaging plate has been packed for over 24 hours
• Unpacked imaging plate has been stored in dark
(not exposed to ambient light) for over 24 hours
By doing this, the erasing procedure will remove any
fogging collected to the imaging plate due to natural
background radiation.

2.1 Imaging plate packing
Note! Do the packing before the patient enters the
reception room, but no more than 24 hours before.

2 Basic use
208396 rev 2 SOREDEX 7
2.2 Taking and processing an image
Power on the unit.
Launch the imaging application software.
Select a patient.
Make an exposure.
Check that the ready arrow is lit in the unit.
Unpack the imaging plate.
Note! Ambient light harms the image information.

2 Basic use
8 SOREDEX 208396 rev 2
Insert the imaging plate with the cover.
Note! Do not partially slide the imaging plate from
the cover. You can place the plate with cover and
leave it to the plate carrier. Unit will not start the
processing before removing the cover.
Remove the cover.
The image appears on the imaging application
screen.
Note! Process within one hour after exposure.
Processed imaging plate is ready to be packed
and exposed again.

2 Basic use
208396 rev 2 SOREDEX 9
2.3 Exposure guidelines
Recommended exposure values (s) for DC x-ray units.
Exposure settings found good for F-speed (Insight) film
can be used (for AC x-ray units increase exposure time by
30%).

3 Advanced use
3.1 DIGORA®Optime setup options
The DIGORA®Optime setup options allow you to configure
the DIGORA®Optime to the user’s clinical preferences.
From the imaging application software you are using select
unit Setup/Scanner page (for more instruction on how to
access setup page review application software manual).
3.1.1 Status
Shows the scanner type, firmware version and unit serial
number.

3 Advanced use
12 SOREDEX 208396 rev 2
3.1.2 Image Scanning
If Show Image Preview and Dental Chart is selected a
preview image with a dental chart for tooth numbering
appears before the image is saved.
3.1.3 Using the dental chart
1. After an imaging plate has been processed a window
opens that shows a preview image and a dental chart.
2. Click the tooth / teeth on the chart that correspond to
the tooth / teeth in the image. Tooth numbers are as-
signed to the selected teeth.
The tools at the top of the window allow the image
to be manipulated.
3. Click OK to save the image and tooth numbers.
3.1.4 Resolution
Super gives a pixel size of 30 μm. This results in images
with better resolution, but may require longer exposure
time to compensate.
High (recommended default) gives a pixel size of 60 μm.
This results in images with less noise especially if short
exposure times are used.
3.1.5 Image Processing - Noise Filtering
Noise Filtering selected (recommended default), makes
images smoother when they are taken at short exposure
times.

3 Advanced use
208396 rev 2 SOREDEX 13
3.1.5.1 Retrieve last image
If the last image processed is not transferred to the PC
because of a network, communication, PC or software
failure, the last image processed can be retrieved.
Note! The LAST processed image can only be retrieved if
the unit is left on. If the unit is switched off the image is lost.
To retrieve the last processed image:
1. Correct the problem that caused the communication
failure. When the connection between the unit and the
PC is re-established the last processed image is auto-
matically transferred to the PC.
2. PC: If the image is not automatically transferred to the
PC, select the Setup > Scanner page from the imaging
application software your are using.
3. PC: In the Last Image field, click Retrieve now to re-
trieve the last processed image.
Note! If required you can select different parameters (e.g.
resolution, show image preview etc.) for the image to be re-
trieved.
4. PC: Click OK to close the Setup window. The last pro-
cessed image is transferred to the PC.
3.1.6 Scanner Unit Serial number
Adds the unit serial number to all new images.
3.2 Settings
See chapter Installation for more information on connecting
the unit to a PC/LAN.

3.3 Workflow
From the imaging application software you are using select
unit Setup / Workflow page.
3.3.1 Readout start
Select Automatic if you want the unit to start automatically
image plate processing.
The Start after options allow to select when the unit starts
image plate processing:
• After Plate insert: processing starts automatically
when it detects right way inserted imaging plate in
the plate carrier.
• After Cover removal: after the imaging plate and
protective cover have been inserted into the plate
carrier,
processing starts automatically when the protec-
tive cover is removed.
