Chapter 1 Introduction
This user manual contains a description, installation of imaging software, operational
instructions and other useful information for the PaX-Primo i digital imaging system.
1.1 Conventions in this guide
The following symbols will be used throughout this manual for the users to keep better
comprehension of their meaning. Make sure that you fully understand them and obey the
instructions they contain.
1.2 Note to the user
This symbol indicates a note to help you get the best performances from the
system. Carefully read these notes to bring about the best performance
possible.
This symbol indicates a warning that should be obeyed with extreme cares.
When missed, it may cause severe damage or physical injuries.
The radiation symbol warns you about radiation dangers.
This indicates a compulsory action or instruction.
X-Ray can be harmful and dangerous if not used properly. The instructions
and warnings contained in this manual must be carefully followed.
As a manufacturer of radiology equipments that conform to stringent
protection standards in force throughout the world, we guarantee a
maximum degree of protection against radiation hazards.
The room in which your radiology unit is to be installed must comply with
all official regulations applicable to protection against radiation. You must
install your radiology unit in a room protected against X-ray emission.

1.3 Warning and safety instructions
An extreme care must be paid when operating this system, since this involves high voltage,
electrical parts inside unit.
To use and operate your panoramic unit and your digital imaging software you must follow the
instructions contained in this manual.
Most of all, the following two things cannot be overstated.
Never expose this equipment to watery material or spray that may lead
to an electrical shock or a damage of equipment.
A small amount of Laser beam could lead to permanent eye injuries.
For maximum safety, advise the patient not to look into the laser beam
directly. And while making adjustments; be sure that beam is not
directed into the patient’s eyes.
1. You are responsible for the operation and maintenance of this unit. Only legally qualified
persons can operate this unit. DO NOT open the cover of the unit.
When necessary, have a trained authorized service technician carry out inspection and
maintenance operations.
2. Install this Unit in an x-ray room that complies with current installation standards. From
this location, you must be able to maintain visual or audio communication with the
patient. This Unit must be permanently connected to the ground with a fixed power
supply cable.
3. DO NOT place the PC and the peripheral equipment connected to it in the immediate
vicinity of the patient in the Unit. Leave at least 1.5 m distance between the patient and
the Unit.

7
4. Leave a sufficient amount of clear space around the CPU to ensure that it is properly
ventilated.
5. X-ray equipment is hazardous to patients and the operator if you do not observe the
exposure safety factors and operating instructions.
6. The patient should wear a protective lead-lined shoulder apron, unless other Radiation
Protection Protocols apply locally.
7. Disinfect any parts of the Unit that come into contact with the patient and the operator
after each patient has been exposed to x-rays.
8. While adjusting the height of the Unit, ensure that the patient is kept clear of the
mechanism.
9. When the Unit is not in use, ensure that the ON/OFF switch is set to OFF (O).
10. Ask the patient to remain still until the Unit arm has stopped moving and the RESET
movement has completed.
11. DO NOT use this Unit in conjunction with oxygen-rich environments. This Unit is not
intended for use with flammable anesthetics or flammable agents.

Chapter 2 PaX-Primo iImaging system overview
2.1 System features
PaX-Primo iis a digital, panoramic dental diagnostic system developed with especially the
affordability in mind without sacrificing performances.
Equipped with a new generation of CMOS digital sensor, PaX-Primo idelivers diagnostic
panoramic x-ray images equal to digital photo quality. Also available is the PaX-Primo i with
optional Adaptive Layer Mode Panoramic Algorithm functionality to produce optimal digital
diagnostic images by using VATECH’s proprietary Area Adaptive Mode (AAM) solution. The
AAM solution captures and instantly processes multiple oral trough layers during a single
panoramic scan. It intelligently reproduces a final diagnostic image by selecting the optimal
single layer in different regions of the image to minimize image distortion in every panoramic
image taken. Both the PaX-Primo i includes a high resolution 10.4” LCD touch panel for easy
operation and simple image previewing. The very compact size and light weight of the PaX-
Primo i family (less than a 4’ cube, and weighing less than 165 pounds), and the ease of
installation will be appreciated by both dentists and dealers. This equipment provides various
features such as the followings.
Among them:
1. Adopting AUTO FOCUSING(Adaptive Layer Mode Panoramic Tomography) algorithm
that enables the system to
zfocus automatically on the object, using artificial intelligent algorithm
zacquire high quality images, regardless of the Arch shape and positioning of the
patient
2. Adopting AAM (Area Adaptive Mode) to minimize image distortion caused from
inappropriate pose in panoramic mode.
3. Providing higher image resolution produced by the advanced CMOS-type sensor that is
made for exclusive use in the panoramic imaging.

9
4. Providing wide touch screen of 10.4" to streamline series of procedures from patient
positioning, to image saving to image reading, thus leading to easier-to-manipulation
than ever before.
5. Improving reliability and dependability by adopting CAN (controlled area network)
protocol that generally is used in areas like airplane leading to greatly reduced problem
occurrences.
6. Positioning patients more accurately in a way that the operator and patient face each
other, resulting in creating much less distorted images.
7. The PaX-Primo
ihas been designed to carry out the following radiological examinations.

2.3 Imaging system construction
There are two different configurations, depending on how the image acquired from the PaX-
Primo iis delivered to the PC for post-processing and viewing. The first configuration makes
use of the Ethernet, whereas the second one is to use the USB card. Each peculiar situation
requires the unique configuration, as the following figures show―mainly the Ethernet availability
between the PC and the equipment. Both configurations do not require the frame grabber cable
for the data transmission any longer. Therefore, there is no need for both PC and the equipment
to be as close as possible to obtain the error-free image.
First the former configuration is explained with data flow algorithm.
The following figure depicts the general direct connection for configuration of the PaX-Primo i
along with the PC through the Ethernet network.
1. PC and the PaX-Primo i connected through the Ethernet

Secondly the latter configuration is explained.
2. No Ethernet network is available
Please do not exit the running image capture program while saving the
captured image on DB. If it is the case, then the captured image got
damaged and you need to retake it again.

This configuration arises when the network between the Unit and PC is not available.
The USB media plays the role of the network to deliver the image from the Unit to PC.
The slot for the USB card is located on the bottom of the touchpad screen and the USB
card is able to save only one shot of the image at a time.
For the image taken to be analyzed, one detaches the SD card (USB) off from the
equipment and brings it where the PC is available with the image viewer─for post-
processing.
2.4 Entering the specific, capturing mode
Currently the automatic recognition between the USB and the network is not supported, which
means that manual selection for either USB or Network is required
To select either one, proceed with the following steps.
1. Turn on the PC.
2. On your desktop, double-click EasyDent or Start>All Programs>EasyDent.
Then a blank EasyDent main screen will be displayed.

14
3. From the main screen, click the Pano icon (Red circle) on the upper left the screen to
run the imaging capture program. Then the following main screen will be displayed
4. From the above figure, click the button in red circle and you are asked to enter the
password. Enter the “vatech” in the lower cases for all.

15
5. The following figure will appear. And go down to the lower right corner to select your
choice from three types.
6. Lastly, save the setting.
Now you are ready to start off.
