Sirona Dental Systems GmbH Introduction
Operator's Manual GALAXIS General information on the use of GALAXIS
bеЦдблЬ
1.2 General information on the use of GALAXIS
Intended use GALAXIS is a software for dental practices and clinics that enables the pre-
paration of three-dimensional volume reconstructions of the maxillofacial re­gion using the GALILEOS dental volume tomograph.
GALAXIS is a component of the GALILEOS system.
The volume reconstructions can be used both for planning and for diagnostic purposes with the help of GALAXIS.
● For example for oral and maxillofacial surgery, plastic surgery and ENT medicine.
The GALILEOS system The GALILEOS system comprises:
● X-ray unit
– The X-ray unit produces two-dimensional images of the head region
via a cone beam with a rotation sequence.
● RCU (Reconstruction Control Unit)
– A reconstruction software converts two-dimensional images into a
three-dimensional volume reconstruction.
– The RCU also manages the software licenses.
● GALAXIS workstation(s)
– Enable(s) the creation of a new three-dimensional volume recon-
struction.
(Call to the X-ray unit to create a new image and to the RCU to con­vert this image into a three-dimensional volume reconstruction).
– The three-dimensional volume reconstructions are displayed and
processed via the GALAXIS software.
– Management of the three-dimensional volume reconstructions
(saving them to and retrieving them from the SIDEXIS database).
● SIDEXIS database
– Storage of three-dimensional volume reconstructions.
IMPORTANT INFORMATION
Add-on modules The functionality of GALAXIS can be extended by installing add-on modules
(e.g. "GALILEOS Implant").
Such add-on modules are supplied with a separate user manual and there­fore are not further explained in this manual.
CAUTION
Compliance with national regulations
Make sure that the use of GALAXIS is compliant with all relevant national laws and regulations.
CAUTION
Restrictions imposed by U.S. American Federal Law
Based on US federal law, the sale of this unit to or by order of physicians, dentists or other trained medical personnel is subject to certain limitations.

3 Starting GALAXIS
Explanation GALAXIS is started via SIDEXIS XG.
Prerequisites In order to start GALAXIS, a 3D X-ray image must be opened in the SIDEXIS
database first.
Simplified invocation 1. Start SIDEXIS XG.
ª The GALAXIS button is displayed as not active (faded) on the toolbar
of the SIDEXIS XG desktop.
2. Select a patient with an existing 3D X-ray image.
3. Select a 3D X-ray image.
ª The selected 3D X-ray image is displayed in SIDEXIS. The GALAXIS
button is displayed as active.
4. Press the GALAXIS button. ª GALAXIS and the selected 3D X-ray image are loaded.
Alternative start options The following alternative options exist for starting GALAXIS via the the SIDE-
XIS XG desktop instead of by pressing the GALAXIS button:
● Via context menu: Select the
"3D"
menu option.
●Via the
"3D"
button in the upper right-hand corner of the 3D image.
NOTICE
If no 3D X-ray images are available, you must create a 3D X-ray image first (see the chapter entitled "Creating a 3D image").

5 Creating 3D X-ray images
Explanation The 3D X-ray images are created via the SIDEXIS XG exposure readiness
function and managed in the SIDEXIS database parallel to other X-ray ima­ges (IO "Intraoral", XP "Panoramic", XC "Ceph", etc.).
At the same time, the 3D X-ray images are stored on the
"3D"
tab card.
Required documentation The operation of the GALILEOS X-ray device is explained in the
"GALILEOS
Operating Instructions"
.
The operation of SIDEXIS XG software is explained in the
"SIDEXIS XG Ope
-
rator's Manual"
.
Creation 1. Start SIDEXIS XG (see
"SIDEXIS XG Operator's Manual"
).
2. Select a patient.
3. Press the 3D Scan button.
4. Press the release button.
After a few minutes, the icon for the 3D X-ray image is displayed on the SI­DEXIS XG desktop.
The 3D X-ray image is now managed in the SIDEXIS database in the same way as any other X-ray image.
CAUTION
X-rays
Make sure that all locally applicable radiation protection regulations are ob­served! Also make sure that the application information provided in the
"GA
-
LILEOS Operating Instructions"
is observed (especially regarding patient
positioning and the start of exposure)!
