Sirona Dental Systems GmbH Introduction

Operator's Manual GALAXIS General information on the use of GALAXIS

båÖäáëÜ

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 re-

gion 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 con-

vert 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 there-

fore 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.

3Starting 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.

ªThe 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.

ªThe selected 3D X-ray image is displayed in SIDEXIS. The GALAXIS

button is displayed as active.

4. Press the GALAXIS button.

ªGALAXIS 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").

5Creating 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 ima-

ges (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 SI-

DEXIS 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 ob-

served! Also make sure that the application information provided in the

"GA

-

is observed (especially regarding patient

positioning and the start of exposure)!

"Panoramic view" workspace Operator's Manual GALAXIS

6.2.4 What is the examination window?

Explanation The display in views is based on a single, three-dimensional vector point in

the reconstructed volume.

● Various different slices of the volume are displayed starting from this vec-

tor point, depending on the view concerned.

● At the same time, the vector point is located in the crosshair of the re-

spective slice axes.

– For this reason, the crosshair is located at the same position within

the volume in all of the views.

– Depending on the type of view concerned, the vector point is located

either in the center of the view or in the examination window of the

view.

– If you navigate through several slices in a view or in the examination

window, the slices in the other views will automatically be adjusted

accordingly.

empty

Example:

If you, for example, move the examination window of the panoramic view, the

transverse views, the longitudinal view and the curved line in the axial plane

will all be altered accordingly.

6.3 "Panoramic view" workspace

Explanation After you start GALAXIS, the selected 3D X-ray image will be displayed in the

classical panoramic view.

In addition to the panoramic view workspace, there is an additional work-

space with both a panoramic and a 3D view.

Brief overview In each view, the fine lines of the crosshair indicate the positions in the other

views to which this corresponds.

empty

Example:

● The horizontal line in the examination window indicates the position in the

axial plane.

– In this way, all views are allocated to each other and the viewer can

easily find his bearings.

● The axial slice also contains a curved line which indicates the position in

the examination window.

NOTICE

Only one view can be active at any given time.
