1 Introduction
You have just received your Visteo digital intra-oral radiology kit. We thank you for the confidence you
have in us and hope that this product will give you entire satisfaction.
We recommend you to read this manual thoroughly before installation; following the guidelines for
installation and usage described in it will exclude risks to the patient and the care team. Please keep it
close to your equipment so you can refer to it at a later date.
Your sensor uses an X-ray sensitive electronic detector (the flat part at the bottom of the sensor) that
replaces the conventional film used for the acquisition of radiological intra-oral images. The X-rays are
automatically detected by the sensor which triggers image acquisition. The acquired image is displayed
almost instantaneously on the screen of the computer to which the sensor is connected. These digital
images can then be manipulated, analysed, saved as files or printed.
The development process of conventional films is thus completely eliminated as well as the possible
influences on image quality; such as the type and age of the chemical product, the temperature of the
baths or the development time.
The sensor is available in two sizes; depending on the kit you have ordered you
received a size 1, a size 2 sensor or both:
•The size 1 sensor allows you to acquire the majority of intra-oral images
(peri-apical and retro-coronary) both vertically and horizontally.
•The size 2 sensor furthermore allows you to easily acquire horizontal
“bitewing” images.
The instructions and information in this manual refer to both sensor sizes, unless
specifically stated. The size of the sensor is marked on the sensor itself.
1.1 Compliance with standards
The Visteo kit is class IIA equipment within the meaning of the European Directive 93/42/CEE concerning
CE markings. The Visteo kit complies with the EN/IEC60601-1 medical standard.
Under certain conditions (see “1.3 Installation precautions”) it is necessary that the other components of
the system that are possibly connected (computer and optional peripherals) are also compliant to standard
IEC950 (EN60950) and that the installation complies with the EN/IEC60601-1 standard.
The intra-oral sensor is contained within a hermetic and sealed case (resistant to immersion).
There is no physical or electrical connection between the Visteo kit and the X-ray generator.

3.1.2 Setup guidelines
The computer and the screen with which the sensor and the box are used should preferably be situated
close to the chair, within the field of vision of the practitioner, to allow for immediate use. Provide visual
access for the patient to be able to share the radiological information with him/her.
The screen must be placed so as to avoid any reflections or direct overhead illuminations that could be
detrimental to the visualization of the radiological images. It must be set up (contrast and brightness) to
display as many grey levels as possible in the image.
The X-ray generator has a great influence on the quality of the acquired images. The kit is compatible with
any kind of generator, be it high-frequency or conventional. The generator must be equipped with an
electronic timer (allowing for very short exposure times) and must emit a dose sufficient for the acquisition
of a good image (with enough grey levels). Make sure that your generator is not worn as the dose emitted
will be insufficient and could influence the quality of the acquired image. The energy emitted by a
generator diminishes over time; when in doubt have your generator checked by a qualified technician.
Make sure he had of the generator is stable, any movement of the head will induce movement blur in the
acquired image.
3.2 Equipment installation
3.2.1 Sensor connections
The Visteo sensor is connected to the positioner, when using the parallel technique to position the sensor
in the mouth, or on the sensor connection cable, when using the bisecting technique to position the sensor
in the mouth. The positioner and sensor connection cable are compatible with the Visteo size 1 and 2
sensors. Please refer to chapter “4 Use” for instructions regarding the positioning in the mouth.
To avoid any fall, always hold the sensor by the lower part (the area that is not sensitive) to unclip
it from the positioner or sensor connection cable.

3.5 Sharing the sensor and box between different workstations
Sharing the sensor and the box allows you to use one or more sensors in turn in a practice with multiple
chairs. It is recommended to link the different workstations in a network to allow for the central storage and
sharing of the images.
The Visteo kit can be shared between different workstations in different ways:
•By moving the sensor and connection box from workstation to workstation; in this case a USB
cable must be plugged into each workstation to allow for an easy connection of the box.
•By moving only the sensor from workstation to workstation; a connection box and a USB cable
must be plugged into each workstation to allow for an easy connection of the sensor.
Windows will automatically recognise the equipment when it is connected and it will be available
immediately for image acquisition.
To enable the sharing of a kit between different workstations, it is necessary to first install the imaging
software for the acquisition of the images, the drivers, O.S.P. tools and sensor installation files on all the
computers to which the box will have to be connected.

EN
Owandy Visteo – User manual Page 16/30
4 Use
4.1 Precautions
Make sure the sensitive surface (the flat surface) of the sensor is directed towards the X-ray
generator. The active surface of the sensor is marked by a frame. The back of the sensor
(rounded) does not react to X-rays and does not produce an image on-screen.
The kit must be manipulated with care, minimising the twisting, pulling and bending of the
attachment cables. Do not step or roll on the cable.
Do not pull on the cable itself but on the plug to disconnect the attachment cable.
Even though the sensor is resistant to impacts, it is strongly recommended to not let it fall on
the floor. If a physical impact should exceptionally happen, contact your distributor and do not
try to intervene yourself.
Do not ask the patient to bite on the sensor or cable.
4.2 Lights and button on the box
During initialisation of the box, the blue and yellow lights light up; once the initialisation finished, only the
blue light remains lit.
4.2.1 Activation of the box
The box automatically switches to standby mode after a period that can be set in the
configuration window (see “3.4 Configuration in the Owandy imaging software” - the
default period is 5 minutes). All lights are off when the box is in standby mode and the
sensor toolbar turns red. To reactivate the box you only need to push the button on the
box.
The lights inform the user about the state of the box:
•Blue light only: sensor ready for image acquisition.
•Blinking blue light: sensor not available (in preparation or transmitting).
•Yellow light: initialisation of the box, an error occurred or the sensor is not
connected; wait, restart the box or connect the sensor.
4.2.2 Rotation pre-selection
It is possible to remotely set the rotation of the sensor form the chair by using the button of the pteo
connection box (similar to the rotation function of the sensor toolbar, see 4.4.2).
By default the acquired images are displayed vertically (image of a tooth
of the upper arch). You can pre-rotate the image before acquisition by
pushing the button of the connection box so that it appears in the right
way on the screen.
You only need to push the button of the connection box when the box is
already switched on (if the box is in standby mode, switch it on by
pushing the button) ; the rotation of the sensor in the mouth is then
displayed on the screen.
Each time the button is pushed, the sensor is rotated 90°to the right. In
this way you can select the rotation that corresponds to the position of
the sensor in the mouth before image acquisition. The image will then be
displayed on the screen in the clinical way.

Owandy Visteo – User manual Page 17/30
4.3 Positioning accessories
The accessories of the Visteo kit allow for the easy and rapid positioning of the sensor in the mouth and in
the same way for all types of images.
4.3.1 Sensor
The sensitive area of the sensor is indicated by a horizontal line; the area below this line is not sensitive to
X-rays.
Make sure that this area is positioned towards the X-ray source when positioning the sensor in the mouth
and that the whole sensitive area is irradiated.
To avoid any fall, always hold the sensor by the lower part (the area that is not sensitive) to unclip
it from the positioner or sensor connection cable.
4.3.2 Positioner
The universal positioner allows for the positioning of the sensor in the mouth with
the technique of parallel positioning. The universal positioner allows for the
acquisition of any type of radiographic image and can be used with the size 1 and
size 2 sensors without having to changer the type of positioner.
The sensor is clipped to the head of the positioner; a rotation allows the user to
position the sensor depending on the tooth or teeth to be X-rayed. Guides on the
cylinder of the sensor allow for a rapid positioning of the sensor for the most
common type of images.
The use of the positioner and the parallel positioning technique is highly recommended for the acquisition
of intra oral radiographic images.

4.3.3 Aiming ring
The aiming ring allows for a rapid and correct positioning of the cone of the X-ray
generator and to ensure that the whole sensitive area of the sensor is irradiated.
The aiming ring is clipped on the rod of the positioner by aligning the notch of the
ring with the centring guide on the rod of the positioner.
4.3.4 Bitewing bite block
The bitewing bite block allows for the acquisition of horizontal and vertical bitewing
images.
The bite block is clipped on the upper part of the rod of the positioner. To correctly
centre the bite block opposite the sensor, the notch in the upper part of the bite
block must be aligned with the guide on the rod of the positioner; push the bite
block against the ridge.
The bite block can also be used for other type of images. The bite block must in this
case be moved away from the ridge to be able to rotate it on the rod of the
positioner and align it with the vertical or horizontal side of the rotated sensor.
4.3.5 Endo bite block
The endo bite block allows for the acquisition of images while an instrument (e.g. a
file) is inserted in one of the root canals of the tooth.
The bite block is clipped on the upper part of the positioner by aligning it over the non-
sensitive area of the sensor (in vertical position). The bite block must be moved away
from the ridge to be able to rotate it on the rod of the positioner. The “basket” of the
bite block is then positioned around the crown of the tooth to be X-rayed, so as to
surround the instrument sticking out of the tooth and to guarantee a suitable distance
between the maxillar and mandibular arches.

4.3.6 Sensor connection cable
The sensor connection cable allows for the positioning of the sensor
in the mouth using the technique of the bisector.
The sensor is positioned manually in this case, maintained by the
patient as with conventional film. This can be necessary for children
with a small mouth.
Clip the sensor to the sensor connection cable and position the
sensor in the mouth, behind the tooth you want to X-ray; the cable
can be turned at an angle to facilitate the positioning in the mouth and to avoid twisting the cable. A cotton
roll can be helpful to position the sensor parallel to the tooth.

4.4 Use of the Owandy XIO StandAlone software
4.4.1 Modes of operation
The sensor kit can function in two ways:
•Through the Twain protocol (for scanners): to use this mode select “Owandy Intra Oral X-rays…”
in the TWAIN acquisition option of your imaging software. Subsequently start the TWAIN
acquisition; the interface is identical to that of the independent mode described below.
•In independent mode: the independent software program can be started with the icon (on
the Windows desktop) or by starting an Owandy software program. This memory resident
software package allows the use of the sensor outside any software program. If an image is
acquired without a program ready to receive it, the resident program will display the image on-
screen for a few seconds and save it in the “C:\Program Files\OWANDY\OSP - XRAYS BOX
STANDALONE\StandAlone\Data” directory on the hard disk. A sensor icon appears in the
Windows taskbar, next to the clock. The colour of the icon indicates the state of the sensor:
Red: sensor inactive
Yellow: sensor initialising
Green: sensor ready for acquisition
4.4.2 Sensor toolbar
It is possible to display the sensor toolbar by clicking with the right mouse button on the sensor icon in the
taskbar. The colour of the sensor toolbar indicates the state of the sensor:
Red: sensor inactive
Yellow: sensor initialising
Green: sensor ready for acquisition
Options of the sensor toolbar:
◄Orientation of the sensor (vertical or horizontal), double-click the icon to change
the orientation of the sensor (same functionality as the button on the connection
box, see 4.2.2).
◄Activate/deactivate the sensor.
◄Iconize the toolbar in the taskbar.
The box automatically switches to standby mode after a few minutes of not being used; the
lights will switch off and the sensor toolbar turns red. Push the button on the box to restart the
kit.
Check the state of the lights on the box and the colour of the sensor toolbar before each
acquisition: the blue light must be switched on and the toolbar must be displayed in green.
