Chapter 2

Getting Started

This chapter includes the following topics:

• Understanding the Ima gi ng Chain on page 2–1

• Adjusting Exposure Time on page 2–5

• Sharing the Sensor Between Workstations on

page 2–9

• Acquiring a Good Image on page 2–10

• Enhancing the Digital Image on page 2–16

Understanding the Imaging
Chain

The imaging chain consists of the following
components:

• Sensor and remote control

• X-ray generator

• Timer

• Computer and monitor

Sensor and Remote Control

The sensor consists of two inseparable parts:

• Sensor

• Remote control

Note

To determine the
exposure time and
create an exposure
time table for your
sensors, see
“Customizing the
Exposure Chart” on
page 2–7.

Note

Because these sensors
are used in the same
manner, this manual
references use of the
size 1 sensor.

Understanding the Imaging Chain

2–2 Getting Started

Sensor

Sensor

The sensor is radio-sensitive. The active surface is the
flat surface marked with the Kodak logo. The marking
#0, #1 or #2 indicates the size of the sensor,
respectively size 0, 1, or 2. The back of the sensor,
non-reactive to x-rays, is rounded and contains the
cable attachment.

Remote Control

The use of your sensor depends on the kit ordered:

• Size 1, universal, sensor—Use for regular

periapical and retro-coronary procedures.

• Size 2 sensor—Use for bitewings and peri-apical

procedures.

• Size 0 sensor—Use for pediatric intraoral exams.

The Size 0 sensor requires less x-ray doses and has
a very small size to fit in a child’s mouth.

Remote Control

The remote control contains all the electronics of the
sensor. The button on the remote control activates, at a
distance, the acquisition in the Kodak dental imaging
software. See “Preparing the Software” on page 2–10.

Understanding the Imaging Chain

KODAK RVG Digital Radiography Systems User’s Guide (CS4000_en) 2–3

The remote control is connected to the computer with
its USB 2 connector . You can connect the remote
control with the power on, when the computer is
switched on. You do not need to start the Kodak dental
imaging software before you connect the sensor.
However, you can acquire the image only in the
imaging module. You can disconnect the remote
control with the power on, but do not disconnect the
remote control when you are acquiring an image. This
can damage the sensor.

X-ray Generator

The x-ray generator has a significant impact on image
quality. Due to its high sensitivity and capacity to store
an enormous quantity of inform ation, the sensor requires
high-energy rays generated over very short time periods.
This way , the im ages are formed by a ma ximum number
of gray levels and you can process the images digitally
to assist in extracting the clinical information. The
Kodak generators meet the requirements.

As a general rule, the sensor is compatible with all
generators provided the generator meets the current
standard of intraoral radiology. You can use a
high-frequency or conventional generator. The
generator must operate with a voltage of 60 to 70kV.

The generator head must have a long cone with a focal
point / film distance of at least 20 cm, to concentrate
the x-rays toward the sensor. Select a mechanism that
supports the generator and provides stability to avoid
any motion blurring due to vibration of the x-r ay sou rce.

Caution!

See “Acquiring
Images” on page 3–1
for the precautions
to take when
connecting and
disconnecting the
sensor in certain
operating modes.

Important

The power of a
generator decreases
over time. Have the
generator inspected
annually to determine
any difference
between its nominal
and effective power.

Important

The sensor is not
compatible with
generators of lesser
specifications.

Understanding the Imaging Chain

2–4 Getting Started

Timer

Use the timer to control exposure times. Depending on
the technologies used, the selected exposure time does
not exactly represent the dose of x-rays output by the
generator since the timing does not systematically take
into account variations in the mains current. Avoid
x-ray sources of inconsistent quality. Use a digital
timer to compensate for current variations in
conventional generators.

You can connect the Kodak generators directly to
the electronics of the sensor to synchronize image
acquisition with the trigger action. This link provides
an ergonomic advantage that eliminates the need for
the operator to click on the acquisition icon prior to
each exposure. See “Preparing the Software” on
page 2–10.

Remember that the image quality for short exposures
is linked to the use of the physical synchronization
function of the sensor and the timer, in particular with
the very high-frequency Kodak intraoral x-ray units.

Adjusting Exposure Time

KODAK RVG Digital Radiography Systems User’s Guide (CS4000_en) 2–5

Computer and Monitor

Place the computer and its monitor in or close to the
operating area, in the visual field of the practitioner
when he is at the chair. Provide visual access for the
patient, to encourage communication. This enables
you to access the RVG system and maintain the
working ergonomics at the chair.

Use a monitor with proper technical display
characteristics for the visualization of radiologi cal
images. Select and set up the monitor according to the
procedure described in the installation guide for the
sensor. Position the monitor to avoid direct light or
reflections that could hinder the reading of the clinical
information.

Adjusting Exposure Time

As in conventional radiology, the exposure time
depends on the following:

• Generator type

• Patient's morphology

• Tooth that is x-rayed

Caution!

A poor monitor
setting or a poor
quality monitor can
cause diagnostic
errors due to the
inability of the
equipment to display
the image properly.
