1.1 Device description
The Planmeca Viso X-ray unit uses cone beam computed tomography
(CBCT) to produce three-dimensional (3D) images of the maxillofacial and
ENT anatomies. Two-dimensional (2D) images are produced with the
tomosynthesis method (panoramic imaging) as well as conventional 2D
radiography (cephalometric imaging, 2D views).
In CBCT a cylindrical volume of data is captured in one imaging procedure.
The data consists of several hundred sample images which are taken from
different directions to cover a certain pre-programmed target area. These
samples are used for 3D reconstruction (using a separate 3D reconstruction
PC) that can be viewed in three dimensions using a separate workstation
and the Planmeca Romexis software.
1.2 Intended use
Planmeca Viso is a system intended to produce two-dimensional (2D) and
three-dimensional (3D) digital x-ray images as well as three-dimensional
(3D) and four-dimensional (4D) optical images of the dento-maxillo-facial,
cervical spine and ENT (Ear, Nose and Throat) regions at the direction of
healthcare professionals as diagnostic support for pediatric and adult
patients.

5 Safety precautions
WARNING
The following safety precautions must be observed in order to avoid the risk
of personal injury or damage to the X-ray unit.
CAUTION
FOR US USERS:
Federal law restricts this device to sale by or on the order of a health care
professional.
CAUTION
This X-ray unit may be dangerous to both patient and operator unless safe
exposure values are used and correct operating procedures are observed.
CAUTION
It is very important that the place where the X-ray unit is to be used and the
position from which the user is to operate the X-ray unit are correctly
shielded.
Since radiation safety requirements vary from country to country and state to
state it is the responsibility of the user to ensure that all local safety
requirements are met.
CAUTION
The patient positioning lights are laser lights. Do not stare into the laser
beam.
CAUTION
If an exposure is interrupted (e.g. exposure button is released or emergency
stop button activated), the patient must be guided away from the X-ray unit
before the C-arm is moved.
CAUTION
Do not connect items which are not specified as part of the system.
CAUTION
Do not touch an electrical connector and the patient at the same time.
CAUTION
If the X-ray unit shows any signs of oil leakage, switch the X-ray unit off and
contact your service technician for help.
CAUTION
Do not use the X-ray unit in an oxygen rich environment or in the presence
of flammable anesthetics.
CAUTION
Never use a defective or damaged X-ray system. Contact your service
technician for help.
5 Safety precautions
User's manual Planmeca Viso G7 5

CAUTION
Do not modify the X-ray unit. The X-ray unit must be serviced by qualified
personnel only.
CAUTION
Be careful that the X-ray unit does not hit the ceiling when you move the X-
ray unit up. The maximum height can be adjusted to suit offices with a low
ceiling. Contact your service technician for help.
CAUTION
Make sure that there is no object under the X-ray unit when you move the X-
ray unit down. If something is in danger of becoming trapped, release the
height adjusting slider immediately to stop the movement. Clear any
obstruction before moving the X-ray unit again.
5 Safety precautions
6 Planmeca Viso G7 User's manual

NOTE
The column movement stops automatically if the emergency stop plate at
the bottom is pressed upward. Clear any obstruction before moving the X-
ray unit again.
NOTE
The adapter base is magnetically attached to the patient support base. This
is a safety feature that ensures that the patient's head cannot get stuck if the
patient faints or begins to fall when they are positioned in the X-ray unit.
NOTE
When positioning seated patients (e.g. in a wheelchair) always first move the
X-ray unit down before you position the patient in the X-ray unit.
NOTE
Cone beam imaging should not be used for routine (or screening)
examinations. The imaging examinations must be justified for each patient to
demonstrate that the benefits outweigh the risks.
NOTE
When it is likely that evaluation of soft tissues will be required as part of the
patient’s radiological assessment, conventional CT or MR medical imaging
should be used rather than CBCT.
NOTE
Before taking an exposure, ask any female patient of childbearing age
whether she might be pregnant. The X- ray unit is not intended for use on
pregnant women.
5 Safety precautions
User's manual Planmeca Viso G7 7

NOTE
FOR CANADIAN USERS:
All patients must be provided with a shielded apron for gonad protection and
a thyroid shield. The use of a thyroid shield is especially important in
children. The shielded apron and thyroid shield should have a lead
equivalence of at least 0.25 mm on both sides (front and back of the patient).
NOTE
If the X-ray unit has been stored at temperatures under +10°C for more than
a few hours, time must be allowed for the unit to reach room temperature
before turning it on.
NOTE
Ensure efficient air conditioning in the X-ray room. It is recommended to
keep the room temperature between +20°C and +25°C at all times.
NOTE
If exposures are taken in rapid succession, the X-ray tube may overheat and
a cooling time will flash on the control panel. The cooling time indicates the
delay before the next exposure can be taken.
NOTE
If the X-ray system is not connected to an Uninterruptible Power Supply
(UPS), switch the X-ray unit off and disconnect the PCs from the mains
during lightning storms.
NOTE
FOR US & CANADIAN USERS:
The laser lights are class II laser products (21 CFR § 1040.10).
NOTE
FOR EUROPEAN USERS:
The laser lights are class 1 laser products (Standard IEC / EN 60825-1:
2007).
5 Safety precautions

NOTE
EMC requirements have to be considered, and the equipment must be
installed and put into service according to the specific EMC information
provided in the accompanying documents.
NOTE
Portable and mobile RF communications equipment can affect the X-ray
unit.
NOTE
External equipment intended for connection to signal input, signal output or
other connectors, shall comply with relevant IEC standard (e.g. IEC 60950
for IT equipment and the IEC 60601 series for medical electrical equipment).
In addition, all such combinations - systems - shall comply with the standard
IEC 60601-1, Safety requirements for medical electrical systems. Equipment
not complying to IEC 60601 shall be kept outside the patient area (more
than 2m (79 in.) from the X-ray unit). Any person who connects external
equipment to signal input, signal output or other connectors has formed a
system and is therefore responsible for the system to comply with the
requirements of IEC 60601-1. If in doubt, contact your service technician or
local representative for help.
NOTE
Contact your service technician if you notice a decrease in image quality.
NOTE
If you take an exposure but the image does not appear in the Planmeca
Romexis program, you can import the image manually into Romexis. Refer
to the Planmeca Romexis User's Manual for details.
NOTE
Do not handle liquids near or on the X-ray unit.

6 Pediatric use
6.1 Introduction
Special care should be exercised when imaging patients outside the typical
adult size range, especially smaller pediatric patients whose size does not
overlap the adult size range (typically children under the age of 13).
Exposure to ionising radiation is of particular concern in pediatric patients
because:
1. For certain organs and tumor types, younger patients are more
radiosensitive than adults (i.e. the cancer risk per unit dose of ionising
radiation is higher for younger patients).
2. Use of equipment and exposure settings designed for adults of average
size can result in excessive and unnecessary radiation exposure of
smaller patients.
3. Younger patients have a longer expected lifetime over which the effects
of radiation exposure may manifest as cancer.
To help reduce the risk of excessive radiation exposure, you should follow
the ALARA (As Low As Reasonably Achievable) principle and seek to
reduce radiation dose to only the amount necessary to obtain images that
are adequate clinically.
