1. INTRODUCTION
The Gendex Orthoralix identifies a range of stand-alone dental
systems, designed for the following radiographic purposes:
1.1. PANORAMIC RADIOGRAPHY (PAN)
Panoramic radiography (also known as orthopantomography -
OPTG) takes X-rays of the whole dento-maxillo-facial complex,
with the following characteristics:
-panoramic: the entire dental and alveolar region including
the rami and the temporo-mandibular joints (TMJ), are
depicted on one radiograph.
-orthogonal: the trajectory of the movement is designed to
keep the projection as orthogonal as possible to the object,
in order to minimize overlapping between structures.
-tomographic: only a limited layer around the plane in focus is
sharply depicted, while the surrounding structures are blurred
by the tomographic movement.
The layer thickness is maximum at the sides and minimum at the
centre.
The operator can select the following projections from the control
panel:
- Standard panoramic projection,
- Child panoramic,
- Dentition only (with improved beam orthogonality),
- Right jaw,
- Left jaw,
- Maxillary sinus, frontal view,
- Right maxillary sinus, lateral view,
- Left maxillary sinus, lateral view,
- TMJ, frontal view,
- TMJ, lateral view (on the central part of the film),
- TMJ, lateral view (on the external part of the film).
1.2. CEPHALOGRAPHY (CEPH)
This operation mode provides X-rays of the skull at large focus film
distance (FFD), under lateral or posterior-anterior projection.
The masticatory system of the skull is shown together with details
of the soft tissue profile from chin to tip of nose.
Special devices are provided to help position the patient and to pre-
set the geometry.
1.3. TOMOGRAPHIC PROJECTIONS (TRANSCAN)
(A) Orthoralix 9200 Plus
Eight tomographic projections are provided, each consisting of 3
views. They include:
- RR posterior layer width 3 mm
- RR posterior layer width 6 mm
- RR incisor layer width 3 mm
- RR incisor layer width 6 mm
- LL incisor layer width 6 mm
- LL incisor layer width 3 mm
- LL posterior layer width 6 mm
- LL posterior layer width 3 mm
(B) Orthoralix DDE
Four tomographic projections are provided, each consisting of 3
views having a layer width of 8 mm. They include:
- RR posterior
- RR anteriror
- LL posterior
- LL anterior
1.4. PHOSPHOR PLATE EXTENSION (PPE)
A special version called Phosphor Plate Extension (PPE) is available:
this consents to use a standard 24 x 30 cm cassette (as available
for computer imaging phosphor plate in medical X-ray) instead of
the current 15 x 30 cm panoramic cassette.
1.5. AUTOMATIC EXPOSURE CONTROL (A.E.C.)
The Automatic Exposure Control (A.E.C.) is based on the use of a
feedback closed loop control on the technique factors influencing
the exposure in order to automatically compensate little differences
in patient absorption and obtain the proper optical density on the
image receptor. In particular the radiation intensity is measured by
an appropriate X-ray sensor during examination and, depending
from the kind of projection, the system modulate the kV or modify
the exposure time (only in Ceph versions without the digital sensor)
in order to obtain the proper optical density for the film.
The purpose is to automatically compensate little differences in
patient absorption around the three predefined patient profile (small,
medium, large) and have all the same consistent film blackening in
the region of interest, while exposing the patient to the smallest
level of radiation.
In the following table is shown in which projections the A.E.C. is
enabled and in which ones not.

At the end of any projection executed with the A.E.C., on the
display is indicated the real kV value generated and the real
exposure time.
The operator can select the A.E.C. mode by actuating the dedicated
button on the operator panel; moreover, this function will be enabled
only when any patient size is selected.

1.6. MOTORISED COLUMN
Instead of the manual vertical movement of the Z-carriage onto
the column, is available a motorised column which allows
automatic vertical movement of the Z-carriage. A motor is mounted
in the top part of the column.
The operator will be able to move vertically the Z-carriage
controlling this motor by:
• two up/down push buttons located on the operator panel
• one push button on the Ceph arm.
The operator must continue to push the buttons to maintain in
movement the Z-carriage.
The buttons control the motor in the following way:
• one-shot short pressure (<500 msec) of the buttons will cau-
se 1 mm movement
• prolonged pressure of the buttons will cause:
- slow movement (3 mm/s), during the first 2 s; on release, a
decelerating ramp is activated (time from Vmax to 0 is
300mS)
- fast movement (20 mm/s), after 2 s.
The vertical movement is stopped by two end run optoswitches
(upper and lower), placed on the front part of the column.

1.7. REAL TIME DIGITAL PANORAMIC
A) ORTHORALIX 9200 DPI
The Orthoralix 9200 DPI is a version of the Orthoralix 9200 family
providing real time digital image acquisition, by using a digital CCD
cassette sensor interconnected with a Personal Computer.
The X-ray Image sensor and the Processing Unit (IPU) is storing the
data (i.e. the digital image) in a memory and then is transferring the
data to a Personal Computer by using an wired connection.
The IPU acquires the image by an autotrigger, as soon the X-rays
are arriving on the digital CCD cassette sensor.
The Orthoralix 9200 DPI operates only in panoramic mode (the
Transcan projections are disabled) so, it can perform the following
projections :
Also the AEC functionality is disabled in the panoramic mode.
Two field upgrading kits to upgrade any Orthoralix 9200\Plus to the
digital panoramic are available (for more information refer to the
relevant Service Manual):
1) 9869 104 01901
2) 9869 104 01911 for systems till s/n 870105
The acquired image will be handled by the Dentsply Gendex VixWin
software supplied with the 9200 DPI.
B) ORTHORALIX 9200 DDE
The Orthoralix 9200 DDE is a version of the Orthoralix 9200 family
providing real time digital image acquisition, by using a digital CCD
sensor interconnected with a Personal Computer, by using an
Ethernet connection.
The Orthoralix 9200 DDE operates in all the enabled projections,
including the cephalometric projections in the versions with the
ceph arm.

4.1. COLUMN
The column is fixed to the wall with four bolts at the top and two at
the bottom.
It includes the counterweights required to balance the Z-carriage.
the Z-carriage is suspended by two steel cables with a balance
mechanism, ensuring a security lock in case one of the steel cables
breaks.
A sliding block on the front, to which the Z-carriage is bolted,
moves vertically along the column.
On the front of the column is the mains power box, to which the
mains power cable is connected.
4.2. Z-CARRIAGE
The Z-carriage slides along the column to adjust to the height of the
patient.
Movement is motorized driven manually by push buttons on the
operator panel.
On the right there is the operator control panel, consisting of a flat
membrane keyboard with alphanumerical display and indicator LEDs.
The internal mounting frame houses an electronic board that controls
the operator interface and the various motor movements.
The kinematic assembly allows for composite movements on the
X/Y plane by independent displacement of the X,Y blocks along
bearings, controlled by gear motors.
Another gear motor is located on the top frame, controlling the
rotational movement of the rotating unit.
A handgrip, bite block (or chin rest), and optical centering devices
provided on the Z-carriage help to position the patient during
exposures.
The bite block and chin rest are exchangeable.
On the right there is an attachment for mounting the Ceph arm.
4.3. ROTATING UNIT
The rotating unit is suspended from the Z-carriage.
It carries:
A ) the tubehead
B) the cassette drive system with the relevant gear motor
C) the digital sensor cassette with the relevant drive system
and gear motor (DPI versions only)
D) the panoramic digital sensor (DDE versions only).
The tubehead is connected by a flange, which can be manually
rotated for changeover from Pan mode to Ceph mode (not applicable
for the DDE versions).
The power converter board, which supplies the high voltage and
filament supply for the tubehead, is located on top of the rotating
unit, on the tubehead side.
4.4. TUBEHEAD
The tubehead contains the high voltage transformer and the filament
transformer with the X-ray tube.
Thanks to the high frequency operation the tubehead features are
reduced in weight and size.
On the X-ray output window the X-ray collimator is mounted ; it is
slit type for Pan, TMJ and transversal scannographic exposures
and can be manually switched to a full size opening in case of Ceph
exposures.
4.5. PATIENT HEAD REST
The patient head rest is attached to the Z-carriage.
It is motorized and controlled by a pair of pushbuttons on the front
operator panel.
4.6. CEPH ARM
The Ceph arm is bolted to the right side of the Z-carriage, and
comprises the cephalostat with cassette support.
In the DDE versions it includes:
A ) the cephalostat
B) the ceph CCD digital sensor
C) the secondary collimator
E) the gear motor and related drive system to move the ceph
CCD digital sensor and the secondary collimator.
4.7. REMOTE CONTROL BOX
The remote control box with exposure handswitch enables the
operator to take an X-ray in a separate room.
It is equipped with a 20m cable for connection to the equipment, and
incorporates an “X-ray ON” buzzer and indicator light.

5.2. MECHANICAL DATA
The system is light-weight thanks to the manufacturing technology
of the high tension transformer, which in turn allows more compact
mechanical dimensioning of the rotary unit and the column.
5.2.1. Driving system
The Orthoralix system provides a microprocessor-controlled motor
driving system, with use of stepping motors, for independent control
of four separate movements:
- X-positioning of rotation centre
- Y-positioning of rotation centre
- rotation of rotating arm
- linear translation of film cassette
- linear translation of digital CCD sensor and secondary
collimator (ceph DDE versions only).
In addition, the patient head rest and the column are also motorized.
Drive transmission is by means of tension belts.
5. TECHNICAL DATA
5.1. PRE-INSTALLATION
5.1.1. Preparing the installation site
Orthoralix 9200 is to be mounted on a normal masonry wall.
It takes three men to attach the column to the wall and to mount the
Z-carriage to the column.
The remaining installation work can be done by one engineer,
following the instructions given in section B of this manual.
Only the standard toolset is required.
Any special devices required for set up and adjustment are supplied
as accessories with the unit.
The system is designed to be fixed to the wall by means of six
bolts.
For this purpose screws M6 with metal expansors are suggested
(supplied); they are only suitable for use with concrete walls type
R300 and over (resistance to compressive load greater than 300
kg/cm2).
For other wall types, please refer to the detailed instructions given
in section B.
Irregularities in the floor level, within a 2mm/m tolerance, can be
compensated at installation time by means of levelling shims (supplied
with the unit).
5.1.2. Headroom
The system height is 2310 mm high.
A minimum headroom of 2340 mm is required to install it.
To dismount the internal parts of the column, such as the slide block
with ball bearings, a minimum headroom of 2650 mm is required.
5.1.3. Floorspace
For the system dimensions applicable to the different versions refer
to AZ-1.
5.1.4. X-ray protection
The machine is intended for (indoor) dental practice without special
X-ray protection in walls, floors and ceilings.
X-ray protection comes from the distance to be kept from the unit,
proper X-ray beam collimation and inherent shielding implemented
in the machine.
Primary X-ray beams are shielded by a lead plate, located at the
rear of the cassette unit (thickness: 1.5 mm in Pan and Transcan
mode, 1 mm in Ceph mode).
In the DDE versions, the X-ray beams are shielded by the sensor
assembly, introducing a filtration equivalent to 1.5 mm of lead.
