Warnings & Safety Instructions
Never…
• place the sensor in a sterilizer or autoclave
• allow the sensor to fall
• pull on the cable, even when removing the disposable protective sheath
• roll or walk on the cable
• request the patient to bite on the sensor or the cable
• disconnect the sensor during the 90 second delay (in non-synchronized mode)
or during acquisition
• force the cable at the sensor side (bend, pull)
• immerse the remote control nor the connector located on the other end of the cable
• Always use the sensor with a hygienic barrier. Change of barrier between each patient.
• After each patient, the RVG 6100 sensor must be thoroughly disinfected. Remove the hygienic
protective sheath and thoroughly clean the sensor with a disinfecting wipe.
• Never immerse the connector located on the other end of the cable, nor the remote control
• Never place the sensor and/or remote control in an autoclave as this could result in serious
damage to the system.
• The cable needs to be cleaned with precaution. We recommend the use of a disinfecting wipe.
Hold the sensor in one hand, with the other run the wipe from the end of the sensor over the first
20 centimeters of the cable WITHOUT PULLING on the cable insulation. The wipe must slide
without forcing it; the pinch of the cable between the fingers must be MINIMAL.

Acquiring an image
1Open the patient file in Kodak Dental Imaging Software.
To launch an RVG image acquisition,
click RVG Acquisition on the toolbar.
Check that the RVG icon in your toolbar is red.
If the icon is not red,
check that the sensor is properly connected
to the computer.
If not, disconnect and reconnect the RVG sensor.
2Cover the sensor with a disposable sheath
and place the sensor on the applicable positioner.

3Select the timer parameters for your generator.
The table below provides you with guidelines for exposure times for an average generator at
70 kV and 8 mA. These are approximative values. Adjust the values for your specific generator.
For patient comfort, position the generator near to
the patient’s head so that the patient does not wait
too long with the sensor in the mouth.

Child with RVG # 0 Tips!
Use the dose indicator to
correctly determine the exposure
time for your generator.
• If the image is too dark or if
the dose indicator is displayed
in red and towards the right of
the band, reduce the exposure
settings
• If the image is too light or if
the dose indicator is red and
towards the right of the band,
increase the exposure settings
• If the dose indicator is displayed
in green and anywhere in the
middle of the band, the exposure
is correct.

4Position the sensor and its positioner
in the patient’s mouth.
NOTE For more details on the type
of positioners, see further in “Different
positioning systems”.in the User’s Guide.
For a mandibular image:
1 Have the patient draw the tongue towards the back of the mouth. Insert the sensor holding it
horizontally.
2 Then turn the sensor downward to place it in a vertical position.
3 Center the sensor on the targeted tooth slide it distally, and ask the patient to push the
tongue to the opposite side. Do not hesitate to compress the mucous membranes to properly
frame the apical area. The patient can then relax the tongue, to allow the sensor to fit
naturally. For premolars and incisors, move the sensor towards the center of the mouth by
compressing the tongue when the mouth closes to relax the muscles.
For a maxillary image:
1 Insert the sensor, maintaining it horizontally.
2 Turn the sensor upward so that it is vertical or parallel to the axis of the targeted tooth.
3 Center the sensor on the tooth to be X-rayed by sliding it distally. Do not hesitate to use the
roundness of the palatal arch and place the sensor at the center of the cavity. 5

5Position the beam indicated device as close as possible to the patient.
6Activate the sensor.
The sensor activation can be done by :
The RVG icon will turn into green
You can also orientate the image before acquisition.
By default, the image displays vertically as if an image
of a tooth from the lower dental arch was acquired.
You now have 90 seconds to take the X-ray image.
7Trigger the X-ray emission.
The image will automatically be displayed on your computer screen.

Enhancing the digital image
The RVG digital images contains a vast quantity of information. To explore the images fully, use the
tools in teh Kodak dental imaging software.
Managing image contrast
The contrasts can be managed, after image acquisition, in a simple and automatic way using the
“Perio”, “Endo” and “DEJ” buttons to enhance the different zones of interest.

Using the filters and main tools
• Sharpness filter: to emphasize a radiological feature that could go
unnoticed in the pure image (lateral ducts or small fissures).
To confirm the interpretation, always remove the Sharpness Filter
and use a contrast tool such as the Highlight.
• Highlight tool: to reinforce contrasts locally (useful for investigating
interproximal caries and detecting caries and fracture).
To use this tool, click on the icon, then click and hold the mouse button
on the image.
• Relief filter: can be used to distinguish and compare between similar
shades of grey.
• Measurement tool: to calculate the distance between points in the images.
Calibrate the tool before measuring.
CAUTION: measurements taken on an X-ray image always contain a certain degree of uncertainty
due to the properties of the radiological examination itself.
