System Overview
Panoramic radiography is a branch of tomography, particularly a branch of rotational tomography.
Images of internal structures of the jaw are created by moving the source and receptor in such a way
as to cause the foreground and background structures to blur, leaving a defined focal trough.
Cephalometric radiography is craniofacial radiography of the bony parts and soft tissue of the head.
It uses parallel X-ray technique to preserve the distance and angle relationship between the anatomic
landmarks.
System Description
The Progeny Vantage® panoramic X-ray system is a computer-controlled multi-axis dental panoramic
and cephalometric radiographic device incorporating:
• X-ray source
• Digital X-ray receptor
• Distributed processing
• WVGA LCD touch screen based operator panel

motorized, 3-speed, telescoping column. Multiple lasers are used to locate the patient and configure
the device to the patient’s morphology.
The outer portion of the column, the fixed column, is mounted to the wall and/or floor. It supports the
inner, moving, or telescoping portion of the column. This inner, telescoping column supports both the
patient positioning table and the overhead arm. The overhead arm supports the C-arm, which in turn
supports the X-ray source, or tubehead, and the panoramic X-ray receptor, or panoramic sensor. The
cephalometric attachment is an accessory that is installed to the highest point of the column. It
contains a cephalometric support arm and a cephalometric scanning mechanism. The scanning
mechanism supports the cephalometric sensor and the cephalometric scanning mechanism.

Area Network (LAN) that allows images to be transferred from the device to any client computer
connected to that network and running the client software. At least one client computer should be
designated to receive the acquired radiographic image at any given time.
Distributed Processing
The Progeny Vantage® is a multi-processor system. Each system monitors itself and reports errors
to the Operator Panel.
The separate processing systems are:
• Real Time Controller (RTC, or system controller) together with the combined X-ray power and
logic boards, and all motor controllers
• Image sensors
• Operator panel
Inter-module communications utilize Ethernet based network, with power over Ethernet (PoE) switch
being located below the patient positioning table.
Movement profiles and the X-ray technique factors are stored in the Real Time Controller and initiated
by communications from the Operator Panel and by the exposure switch. The RTC controls the
motion produced by the individual motors via commands send thru a dedicated serial link. The RTC
also controls the X-ray generation by commands send to the power and logic boards via a second
serial interface.
Software Architecture
The three separate processing systems run a software to control all aspects of device operation. The
operator panel keeps track of overall system operation, communicating with all subsidiary processors.
The remaining processing systems (RTC and X-ray sensors) all report status to the operator panel,
where the appropriate operations are initiated. Movement and X-ray control are handled by the RTC,
under the parameters communicated to it by the operator panel. The sensor performs all initial
collection and processing of the image before delivering it to the operator panel, wherein secondary
image processing is applied. All system user settings are maintained on the operator panel.
Mechanical and X-ray calibration information are maintained on the RTC and X-ray controller
respectively. The sensor calibration information is maintained on the operator panel and on the
sensor, depending on the level of the calibration information (high vs. low). The processing systems
move together through the various states used to produce the device functions.
About the Components
The Progeny Vantage® panoramic X-ray system includes the following components.
Vertical Column
The vertical column has two main parts: the fixed section and the moving, or telescoping, section.
The fixed section contains the actuator to control up and down movement of the panoramic X-ray
device. The telescoping section contains the positioning lasers. Optical sensors in the telescoping
section define the maximum and minimum extension of the column.

Progey Vantage® Panoramic X-ray System
Technical Service Manual
Theory of Operations
Telescoping Section
Fixed
Patient Table
The column is comprised of two extrusions, connected by bearings and a linear actuator. The
bearings are adjustable to align the extrusions to each other, and to minimize slop. The linear actuator
is a gear driven screw with integral brake. The column, actuated by a push button operator panel
located on the side of the patient positioning table, moves at three progressively faster speeds, with
a smooth transition between speeds.
Vertical column
Patient Positioning Table
The patient positioning table guides and supports the patient during acquisition of panoramic X-ray
images by means of the chin rest, bite guide, and positioning wands.
Correct and repeatable patient positioning is essential to producing a clinical-quality image. Patient
positioning is accomplished by the telescoping column, the temple wands, and the reference lasers.
All of these subsystems are actuated by a push-button panel located on the left and the right sides of
the patient positioning table.
The temple wands are located on either side of the chinrest/bite piece assembly. The wands use a
spring to close against the patient’s head, and a motor to open. The maximum opening is controlled
by an optical sensor mounted inside the positioning platform. At any point, the wands can be manually
opened further against the spring.

Column Computer
The column computer, mounted on the lower half of the telescoping section of the column, acts as
interface controller to the machine and provides the basic image processing. It has two network
interfaces, one connected to the in-machine network, and the other connected to the office LAN. The
column computer is powered through the 48 V power supply embedded in the column carrier board
located below the patient positioning table.

files. The software on the column computer provides top-level control on the Progeny Vantage
based on the touch screen commands given by the operator panel. The software also transfers the
image to the Client computer for further processing and storage.
Lasers
There are four reference lasers for locating the patient’s head relative to the device: the Median
(midsagittal) plane, the Frankfort plane, and two Cuspid plane lasers.
The Median (midsagittal) plane provides the vertical center plane reference. It is a fixed laser and is
located on the telescoping section of the column behind the upper cover.
The Frankfort plane provides a horizontal planar reference, and is adjustable vertically to correspond
to the patient’s physiognomy. It is mounted to the inside of the upper column cover, and is mountable
to either the left or the right side of the column upper cover.
The Cuspid lasers are mounted within the patient positioning table and are directed by mirrors up to
the patient’s mouth. The Cuspid lasers are carried on a transit that moves fore and aft. The transit
movement is reported to the real-time controller (RTC) by a slide potentiometer. To define the zero
position for the Cuspid lasers, a hole in the transit is aligned with a similar hole in the patient table
using a precision pin.

Overhead Assembly
The overhead assembly consists of an overhead (swing) arm and C-arm. The overhead arm supports
the C-arm, which rotates. The C-arm includes the tubehead and the removable sensor. The tubehead
produces the X-ray beam, and the sensor is a digital image receptor.
Overhead assembly
Overhead Arm – Y-axis
For the lateral Y-axis motion, the overhead arm pivots about bearings located in the mounting casting
fastened at the top of the column. Its motion is produced by a ball screw drive with one end connected
to the mounting casting and other end to the overhead arm itself. The stepper motor is near the
column. Both mechanical connections of the drive assembly are through ball bearing assemblies.
An optical sensor on the mounting casting engages a flag on the overhead arm to define a home
reference for the system. Motion is monitored by a potentiometer connected to the ball bearings at
the column end of the drive assembly. To define the zero position for the system, a hole in the swing
arm is aligned with a similar hole in the mounting casting using a precision pin.

C-arm
Overhead Arm – X-axis
For the in-and-out X-axis motion, the translation drive of the overhead arm (X-axis) is comprised of a
plate mounted on linear bearings attached to the overhead arm casting. The plate is moved by a
backlashless screw drive with a stepper motor on the fixed end. Position feedback is via a linear
potentiometer with an optical sensor and flag for home reference. A hole in the plate aligns with a
hole in the overhead arm casting using a precision pin to define a system zero position.
C-arm
The C-arm is suspended on a pair of bearings mounted to the underside of the X-axis translation
plate. The C-arm casting incorporates an internal tooth ring gear that meshes with a pinion gear on a
stepper motor mounted on the X-axis translation plate. The motor is spring loaded to maintain positive
mesh and minimize slop.
C-arm
X-ray Source
The X-ray tubehead contains a high-frequency X-ray source that uses a stationary anode X-ray tube
(See Appendix in Progeny Vantage
that is comprised of a power board and a logic board controls and monitors the operation of the X-ray
tubehead. The operation of this circuit is governed by the RTC and is locally controlled by
microprocessor on the logic board. Power for the X-ray source is derived directly from the power
supply mains.
There are no serviceable parts inside of the X-ray tubehead and it must not be opened in the field.
Opening the X-ray tubehead will compromise the high-voltage and X-ray protections embedded
inside of the device and may endanger patient and operator.
The primary collimator is mounted on the output port of the X-ray tubehead. The collimator is a 2-axis
motorized automatic beam-limiting device, whose operation is governed by the RTC and locally
controlled by a motor controller. The two axes are controlled by a single motor controller in sequential
manner. A relay mounted the collimator (motor controller) carrier board directs the motor drive current
as appropriate for the controlled collimator axis.

very large X-ray camera that converts the X-ray to electrical signals, precise circuitry that processes
these signals, frame memory that stores the image between the imaging sessions, and
microprocessor that controls the sensor operation and communicates with the column computer via
an Ethernet connection. The device is powered through the Ethernet connection from the PoE switch
located below the patient table.
The X-ray sensor circuitry is sensitive to impact and the device must be handled with care. There are
no serviceable parts inside of the X-ray sensor and it must not be opened in the field. Opening the
sensor will compromise the X-ray performance of the device and may endanger the patient.

sensor. The difference between the two types is the size of the X-ray active area. The cephalometric
sensor has 50% larger active area than panoramic sensor and therefore the cephalometric sensor
may be used as a panoramic sensor, but the panoramic sensor cannot be used as a cephalometric
sensor.

Mechanism
The X-ray sensor implementation automatically converts the cephalometric sensor to panoramic
sensor based on the position ID reported from the floating connector board embedded in the sensor
mount on the C-arm or on the cephalometric transit. In addition, the sensor mount on the
cephalometric transit and the cephalometric sensor contain a mechanical key that do not allow a
panoramic sensor to be attached to the cephalometric accessory. This mechanical key consists of a
pin attached to the sensor mount on the cephalometric transit and a hole embedded in the
cephalometric sensor.
Cephalometric Attachment
The Cephalometric Extension consists of the support arm, the cephalometric scanning mechanism,
and the cephalometric sensor.
Support Arm
The support arm is an aluminum casting that mounts to the panoramic column’s inner (mobile)
component. It mounts via a support casting that allows vertical adjustment of the position of the
cephalometric mechanism. The arm can be mounted either to the right, or to the left of the column.
Cephalometric Scanning Mechanism
The cephalometric scanning mechanism is comprised of the rail and the transit assembly. The rail
supports the transit mechanism, and houses the motor and bearings that cause the transit mechanism
to move. The transit assembly mounts the cephalometric sensor and the secondary collimator,
maintaining the alignment of the sensor and secondary collimator to the X-ray tubehead.
The rail also supports the cephalostat, used to position the patient. The cephalostat is comprised of
two earposts that adjust to conform to the width of the patient’s head, and a nasion locator, which
adjusts vertically and laterally to align the patient’s head. The entire cephalostat rotates in 45°
increments to support many cephalometric imaging positions.

Client Computer
The client computer is a computer connected to the same local network where the Progeny Vantage®
device is connected. The client computer executes the Client software designed by Midmark and
exclusively communicates with the operator panel in the process of radiographic image acquisition in
order to obtain, process, and store the acquired image.

Theory of Operations
The client computer could be installed either in close proximity to the Progeny Vantage® machine or
could be located in a dental operatory or other suitable and accessible location. It could be also
permanently or temporary assigned. In case of temporary assigned client computer, multiple
computers could act as client computer, one at a given time.
Operational Systems
The various processing systems in the Progeny Vantage® panoramic X-ray system are stand-alone
modules, each with their own diagnostic procedures.
User Interface
The user interface is provided by a tablet-style operator panel that is connected to the column
computer running the Progeny Vantage

X-ray Generation
For the generation of X-rays, parameters are passed from the operator panel to the RTC defining the
desired technique factors and exposure time. Upon actuation of the exposure switch, the RTC passes
the necessary information to the X-ray controller to produce the desired exposure. The exposure
switch is also connected to the X-ray controller. Upon receipt of the exposure parameters from the
RTC, and the signal from the exposure switch, the X-ray controller then initiates, controls, and
terminates the exposure.
The exposure switch is routed through the emergency stop switch, before it reaches any control
functionality in RTC or the X-ray controller. That will cause the X-ray generation to be interrupted in
case of activation of the emergency stop switch by the operator.

Motion Control
The Progeny Vantage® utilizes eight motors:
• Telescoping column drive motor
• Patient positioning wand motor
• Primary collimator x-axis motor
• Primary collimator y-axis motor
• Swing arm motor (overhead assembly)
• Transition drive motor (overhead assembly)
• C-arm drive motor (overhead assembly)
• Cephalometric transit motor
The column drive is an integral DC linear actuator embedded in the telescoping column. Limit of
motion is governed by flags, mounted on the fixed portion of the column, which are sensed by two
optical sensors mounted on the telescoping portion of the column. The column drive uses a motor
controller board similar to the others, but it is designed to operate a brushless DC motor instead of a
stepper motor.
The positioning wands use a stepper motor to open the wands. Closure of the wands is produced
using a spring. In any position defined by the motor, the wands are free to open against the spring.
The open position of the wands is defined by an optical sensor.

Theory of Operations
The collimator is a 2-axis motorized beam-limiting device. The two axes are controlled by a single
controller in sequential manner. A relay mounted the collimator (motor controller) carrier board directs
the motor drive current as appropriate for the controlled collimator axis.
The tomographic effect needed for panoramic image is produced by a 3-axis, computer-controlled
assembly resident completely in the swing arm of the overhead assembly. The three axes are:
• Y-axis – the swing arm of the overhead assembly, which produces the side-to-side motion
• X-axis – the translation drive of the overhead assembly, which produces the in and out motion
• R-axis – the C-arm drive which produces the rotational motion
®
The cephalometric image in the Progeny Vantage
is produced by 5-axis, computer-controlled motion
– the 3-axis of the swing arm, one additional axis in the cephalometric scanning mechanism, and the
x-axis motion of the collimator.
All motion components except the primary collimator are controlled by separate motor controller
boards and the two axis of the primary collimator are controlled by a single motor controller board.
The boards are linked to the main system controller (RTC) via dedicated serial communication
channel, which addresses each of the motor controllers by their unique address.
All motors are powered by a dedicated motor power supply line (24 V), called motor power, that is
enabled or disabled by RTC also. Each motor controller is set to a power level that corresponds to
the needs of the motor driven.
The motor power is routed through the emergency stop switch. That allows the motion to be stopped
immediately at any time when the emergency stop switch is activated by the operator.
System Diagnostics
The Progeny Vantage® incorporates an extensive diagnostic system to aid in recording and
troubleshooting system errors.
Errors generated by any subsystem are reported to the column computer, which records them in a
log. The errors are reported to the user via a pop-up window. Within the pop-up window is a link to
the system Message Center where the detailed message can be reviewed. The Message Center can
sort system error messages by date, subsystem, and content. Error messages contain a high-level
error number, which identifies the subsystem, and a low-level error number to identify the exact error.
Image Acquisition and Transfer
To produce an image, the motion profile and X-ray technique factors are selected on the operator
panel, and the column computer communicates them to the RTC. When the column computer
receives a command to move to the Ready for imaging (RFI) position, it passes the profile and
technique factors to the RTC, and commands the RTC to move to RFI. After moving to RFI, the RTC
arms itself and arms the X-ray controller. Meanwhile, the column computer has also commanded the
sensor to prepare to receive X-rays.
Upon closure of the exposure switch, the RTC begins providing motion parameters to the various
motor controllers and X-ray parameters to the X-ray controller. This continues for as long as the
exposure switch remains closed, or until the parameters of the profile are exhausted.
When the sensor detects X-rays, it begins recording the image. The sensor continues recording for a
time sufficient for the longest exposure. The sensor transfers a preview image (low resolution) and
final image (high resolution) to the operator panel. The preview image is used to generate progress
indication for the image acquisition. When the operator panel receives the complete final image, it
then processes it with the relevant calibration data and sends the final image to the client computer
for further processing with the user-selected filters. The client computer then stores the image and
passes the image to the imaging application.
If, at any time during the creation of the image, the exposure switch is released (opened), the RTC
immediately ceases transmitting parameters and instead transmits a stop command to the motor
controllers and deactivates the X-ray controller. It also advises the column computer of the
